Solar flares as a physical process. Study of solar activity

B.V. Somov, Doctor of Physical and Mathematical Sciences, State Astronomical Institute. PC. Sternberg, Moscow State University

During the big flash, the flow of hard electromagnetic radiation The sun increases many times. In invisible to us ultraviolet (UV), X-ray and gamma rays, our luminary becomes "brighter than a thousand suns." The radiation reaches the Earth's orbit eight minutes after the start of the outbreak. After a few tens of minutes, streams of charged particles arrive, accelerated to gigantic energies, and after two or three days - huge clouds of solar plasma. Fortunately, the ozone layer of the Earth's atmosphere protects us from hazardous radiation, and the geomagnetic field - from particles. However, even on Earth, especially in space, solar flares are dangerous and it is necessary to be able to predict them in advance. What is a solar flare, how and why does it occur?

sun and us

The closest star to us - the Sun - was born about 5 billion years ago. Inside her go nuclear reactions that make life possible on Earth. Theoretical models of the structure and evolution of the Sun built on the basis of modern observations leave no doubt that it will shine for billions of years.

Solar radiation is the main source of energy for the earth's atmosphere. Photochemical processes in it are especially sensitive to hard UV radiation, which causes strong ionization. So when the Earth was young, life only existed in the ocean. Later, about 400 million years ago, the ozone layer appeared, absorbing ionizing study, and life came to land. Since then, the ozone layer has protected us from the damaging effects of harsh UV radiation.

The magnetic field of the Earth, its magnetosphere prevents the penetration of fast charged particles of the solar wind to the Earth (Earth and Universe, 1974, No. 4; 1999, No. 5). When its gusts interact with the magnetosphere, some of the particles still fall out near the Earth's magnetic poles, generating auroras.

Alas, the harmony of our relationship with the Sun is violated by solar flares.

Solar flares

Over the past decades, several space observatories have been staring at the "angry" Sun with the help of special X-ray and UV telescopes. Now there are four such spacecraft: American "SOHO" (Solar and Heliospheric Observatory - solar heliospheric observatory; Earth and Universe, 2003, No. 3), "TRACE" (Transition Region and Coronal Explorer - researcher of the corona and transition layer), "RHESSI" (Ramaty High Energy Solar Spectroscopic Imager - solar spectral telescope of high-energy radiation named after Ramati) and the Russian satellite "Koronas-F" (Earth and Universe, 2002, No. 6).

The huge interest in solar flares is not accidental. Large flares have a strong impact on near-Earth space. Fluxes of particles and radiation are dangerous for astronauts. In addition, they can damage electronic devices spacecraft, disrupt their work.

UV and X-rays from the flare suddenly increase ionization in upper layers Earth's atmosphere, in the ionosphere. This can lead to disruptions in radio communications, malfunctions in the operation of radio navigation instruments of ships and aircraft, radar systems, and long power lines. High-energy particles entering the Earth's upper atmosphere destroy the ozone layer. The ozone content is decreasing from year to year. A scientific discussion is raised by the question of the probable connection between the flare activity of the Sun and the climate on Earth.

Shock waves and solar plasma ejections after flares strongly disturb the Earth's magnetosphere and cause magnetic storms (Earth and Universe, 1999, No. 5). It is important that the perturbations magnetic field on the Earth's surface can affect living organisms, the state of the Earth's biosphere (Earth and Universe, 1974, No. 4; 1981, No. 4), although this effect seems negligible compared to other factors of our daily life.

Outbreak forecasting

The need to predict solar flares arose long ago, but is especially acute in connection with manned space flights. For a long time, two approaches to solving this problem were developed almost independently and practically without results. They can be conditionally called synoptic and causal (causal). The first - similar to weather forecasting - was based on the study morphological features preflare situations on the Sun. The second method implies knowledge of the physical mechanism of the flare and, accordingly, recognition of the pre-flare situation by modeling it.

Before the beginning space research, for many years, observations of flares were carried out mainly in the optical range of electromagnetic radiation: in the line of hydrogen Na and in "white light" (continuous spectrum of visible radiation). Observations in magnetically sensitive lines made it possible to establish a close relationship between flares and magnetic fields on the solar surface (photosphere). The flash is often seen as an increase in the brightness of the chromosphere (the layer directly above the photosphere) in the form of two luminous ribbons located in regions of magnetic fields of opposite polarity. Radio observations confirmed this pattern, which is of fundamental importance for explaining the flare mechanism. However, his understanding remained at a purely empirical level, and theoretical models (even the most plausible) seemed completely unconvincing (Earth and Universe, 1974, no. 4).

Rice. 1 - Solar flare (x-ray index X5.7) recorded on July 14, 2000 from the TRACE and Yohkoh satellites. An arcade of flare loops is visible: on the left in the UV (195 A); in the center - in soft x-rays; on the right - sources of hard x-ray radiation(53 - 94 keV), located along the flare ribbons - the base of the arcade. NL - photospheric neutral line.

Already the first extra-atmospheric spacecraft observations showed that solar flares are a coronal rather than a chromospheric phenomenon. Modern multiwavelength observations of the Sun from space and ground-based observatories indicate that the flare energy source is located above the arcade of flare loops ( light stripes in the figure on the left) in the corona, observed in soft X-ray and UV radiation. The arcades are based on chromospheric flare ribbons, which are located on opposite sides of the polarity dividing line of the photospheric magnetic field, or photospheric neutral line.

Flash energy

A solar flare is the most powerful of all manifestations of solar activity. The energy of a large flare reaches (1-3)x1032 erg, which is about a hundred times higher than thermal energy, which could be obtained by burning all the explored reserves of oil and coal on Earth. This gigantic energy is released on the Sun in a few minutes and corresponds to an average (during the flare) power of 1029 erg/s. However, this is less than hundredths of a percent of the power of the total radiation of the Sun in the optical range, equal to 4x1033 erg/s. It's called the solar constant. Therefore, during a flare, there is no noticeable increase in the luminosity of the Sun. Only the largest of them can be seen in continuous optical radiation.

Where and how does a solar flare draw its enormous energy?

The flare energy source is the magnetic field in the Sun's atmosphere. It determines the morphology and energy of the active region where the flare will occur. Here the field energy is much greater than the thermal and kinetic energy plasma. During a flare, the excess field energy is rapidly converted into particle energy and plasma changes. The physical process that provides such a transformation is called magnetic reconnection.

What is a reconnection?

Consider the simplest example, which demonstrates the phenomenon of magnetic reconnection. Let two parallel conductors be located at a distance of 2l from each other. On each of the conductors flows electricity. The magnetic field of these currents consists of three different magnetic fluxes. Two of them - F1 and F2 - belong respectively to the upper and lower currents; each stream spans its own conductor. They are located inside the separatrix line of the field A1A2 (separatrix), which forms a "figure eight" with the intersection point X. The third flow is located outside the separatrix line. It belongs to both conductors at the same time.

If we shift both conductors towards each other by the value dl, then the magnetic fluxes will be redistributed. Own flows of each of the currents will decrease by dФ, and their total flow will increase by the same amount (combined flow Ф1 "and Ф2"). This process is called magnetic field line reconnection, or simply magnetic reconnection. It is carried out in the following way. Two field lines approach the point X from above and below, merge with it, forming a new separatrix, and then join so as to form a new field line that spans both currents.

Rice. 2 - The magnetic field of two parallel electric currents of the same magnitude I:

a) at the initial moment of time; A1A2 - separatrix; Ф1Ф2 - magnetic flux before reconnection;

A3 - field line of the total magnetic flux of two currents;

b) after the conductors are displaced by a distance dl to each other. A1A2 - new separatrix; Ф1Ф2 - reconnected magnetic flux. He became a common stream of two currents; line X runs perpendicular to the plane of the figure;

c) magnetic reconnection in plasma. An intermediate (pre-flare) state with a non-reconnecting (slowly reconnecting) current sheet CL is shown.

We note that such reconnection in vacuum, for all its simplicity, is a real physical process. It can be easily reproduced in the laboratory. Magnetic flux reconnection induces electric field, the value of which can be estimated by dividing the value dФ by the characteristic time of the reconnection process dt, that is, the time of movement of the conductors. This field will accelerate a charged particle placed near the X point, more precisely, the X line.

At the beginning of the last century, it was noticed that solar activity has a direct impact on the Earth, as well as on all living and non-living objects on it. And one of the most significant manifestations solar activity are solar flares. Today, this phenomenon is studied by scientists in dozens of research centers and institutes located in different parts of the world. Why do flares occur on the Sun, and what effect do they have on our lives? You will find answers to these questions in this article.

Causes of solar flares

Like any other star, the Sun is a huge ball of gas. This ball rotates around its axis, but does it differently than our planet or other solid body. Rotational speed different parts this star is different. The poles move slower and the equator moves faster. As a result, the magnetic field of the Sun, together with the plasma, twists in a special way and is strengthened to such an extent that it begins to rise to its surface. In these places, activity increases and outbreaks appear.

In other words, the rotational energy of the luminary is capable of transforming into magnetic energy. And in those places where too much of this energy is released, flashes occur. This process is easy to imagine using the example of a conventional electric light bulb connected to the network. If the voltage in the network rises excessively, the light bulb burns out.

What happens during solar flares

Flashes release huge amounts of energy. During each of them, billions of kilotons of TNT are released. The amount of energy from one solar flare is more than can be obtained from burning all the explored this moment oil and gas reserves on earth.

As a result of flashes, a large number of plasma, which forms the so-called plasma clouds. Driven by the solar wind, they head towards the Earth and cause geomagnetic storms that have a strong impact on our planet.

How solar flares affect technology

Scientists have identified the direct impact of flares on the Sun and the following geo magnetic storms for the work of various technical devices. And it is truly grandiose. Unfortunately, solar flares can only affect man-made devices negatively.

Often during these periods, radar devices fail or work intermittently. During solar flares, communication with ships and submarines is often lost. The greatest danger is this species solar activity and for aircraft. During outbreaks, the navigational instruments of airliners sometimes stop working. If this happens during takeoff or landing, there is a direct threat to the lives of passengers and crew members.

Suffer during outbreaks and ground equipment. First of all, this applies to devices that transmit and receive GPS signals. Therefore, due to solar flares, car navigators may not work properly or not work at all, Cell Phones and other GPS-enabled devices.

How solar flares affect the human body

For the first time, the now famous scientist Chizhevsky spoke about the effect of outbreaks on living beings, including people, at the beginning of the 20th century. However, at that time his arguments were ridiculed as pseudoscientific. And only after many decades, researchers discovered the strong influence of solar flares on human body. Unfortunately, as in the case of technology, this type of solar activity is extremely unfavorable for people.

First of all, children and the elderly, as well as sick and weakened people, suffer from the consequences of solar flares. But everyone else, one way or another, feels their influence on themselves, even if they don’t think about it.

So, for example, every healthy adult can probably remember the moments when he experienced a clear breakdown without any apparent reason. Of course, such a situation can occur in different occasions. But very often it is caused by solar flares or geomagnetic storms that occur after them.

Scientists have found that during this period the blood thickens. In this regard, solar flares are especially dangerous for people suffering from hypertension or prone to blood clots. Anyone who has similar health problems should definitely follow the forecast of geomagnetic storms. During the period of their onset, you must always have the necessary medicines on hand.

Solar flares have an adverse effect on the human cardiovascular system. For this reason, the number of heart attacks and strokes increases during them. People suffering from any chronic diseases sometimes experience exacerbations during outbreaks. And for those who are completely healthy, sometimes there is causeless fatigue, apathy, loss of strength.

Influence on the human psyche

These phenomena provide Negative influence on the human body, both physiologically and psychologically. So, even absolutely healthy people at this time often experience increased irritability and nervous excitability - or, on the contrary, lethargy and depression.

Scientists have found that during solar flares, people's attention deteriorates and the speed of reaction to external stimuli decreases. For this reason, the number of traffic accidents increases at such times. In addition, during these periods, the number of industrial accidents increases, the cause of which is the human factor.

In people with mental illness and deviations during flares on the Sun, exacerbations are often observed. In addition, it has long been noted that at such times the number of suicides increases.

Although flashes on the Sun do not bring anything good for our planet and its inhabitants, we should not forget that this star gives us heat and light. We hope that the information given in our article will help weather-sensitive people to act correctly during solar flares and geomagnetic storms.

For decades now, scientists different countries trying to figure out how to predict such natural phenomena as solar flares. Their frequency is determined by eleven-year cycles of solar activity. However, the most powerful and unpleasant manifestations of the activity of the Sun overtake us, quite suddenly, to this day. This is due to the fact that solar flares can only be predicted by analyzing magnetic solar fields that are not constant and at least minimally stable.

The impact of solar flares on outer space

Solar flares are considered the most unfavorable for space explorers. Posing the greatest threat in the vast outer space, waves of powerful explosive energy may well damage communication satellites, and even spacecraft, completely disabling instruments and control systems. Flashes on, forming powerful streams of protons, significantly increase the level of radiation, as a result of which people in open space can easily be exposed to strong radiation. A certain risk of exposure exists even for passengers of airliners who fly during certain periods attributable to the peaks of outbreak activity.

Under the Soviet Union, leading experts at the Crimean Astrophysical Observatory tried to predict the likelihood of solar flares, and if the prerequisites for an energy explosion arose, cosmonauts’ flights to without fail postponed. In 1968, the forecast of Soviet scientists about the upcoming solar flare, which was awarded the most high level danger - three points. Then spaceship"Soyuz-3" with Georgy Beregov was landed, and after three hours they observed a powerful flare on the Sun, which for a person in space would be fatal.

Plasma cloud danger and solar flare classification

Solar flares can pose a considerable danger to the inhabitants of our planet, even though the Earth is protected from them by the geomagnetic field and the atmospheric ozone layer. Each such flash is accompanied by a cloud of a kind of plasma and, reaching the Earth, it is this plasma that causes magnetic storms that negatively affect almost all living organisms and disable the most powerful communication systems.

After the onset of a solar flare, radiation reaches the Earth's surface within an 8-10-minute period, after which powerfully charged particles are sent towards our planet. Further, within a three-day period, the plasma clouds reach the Earth. A kind of blast wave collides with our planet and causes magnetic storms. The duration of each outbreak usually does not exceed a few minutes, but this time and the power of the energy release is quite enough to affect the state of the Earth and the well-being of its inhabitants.

scientists solar flares have been classified into five types: A, B, C, M, X. In this case, A are flares with a minimum degree of X-ray emission, and each subsequent one is 10 times more intense than the previous one. Class X flares are considered the most powerful and dangerous. Numerous scientists and researchers have noticed that even typhoons, hurricanes and earthquakes most often occur during solar activity. Therefore, forecasts of various natural disasters are often associated with solar flares.

The main types of danger in solar flares

Without exaggerating the level of influence of solar flares on the human body and well-being, it is possible to determine the groups of people who are most susceptible to negative impact solar system energy explosions.

It has been proven more than once that catastrophes and accidents due to the fault of the human factor increase quantitatively during the days of solar flares. This is due to the fact that during such periods, brain activity is maximally weakened, and concentration of attention is greatly dulled. In addition, for a number of people, magnetic storms are the causative agents of real torment and frustration. There are many such groups:

• People with weakened immune systems;
• The population suffering from cardiovascular diseases, migraines, jumps (drops) in blood pressure;
• People with chronic conditions that get worse during each outbreak solar energy and subsequent magnetic storm;
• Population subject to periodic manifestations of insomnia, loss of appetite, restless sleep;
• Mentally unbalanced individuals.

There are separate opinions, repeatedly confirmed in practice, that many during magnetic storms begin to be disturbed by old wounds, scars, damaged bones or sore joints. Also, those representatives who have a so-called delayed reaction to magnetic storms can be attributed to a separate group. These are people who experience negative effects a few days after solar flares.

Many experts advise periodically undergoing medical examinations to identify chronic diseases. Since it is precisely this kind of disease that is significantly aggravated during solar flares, it will be possible, if not to prevent the upcoming malaise and deterioration in health, then at least to have medicines at hand.

How scientists are trying to predict solar flares

Given the degree of influence and danger from solar flares, work and attempts to find the most accurate methods for predicting this phenomenon do not stop. For a long time, scientists and weather forecasters considered two ways to solve the problem:

1. Casual - is based on predicting the next outbreak by its simulation, for which the physical mechanisms of the outbreak are carefully studied.
2. Synoptic - a method that involves the study and analysis of the prerequisites and behavior of the Sun before each flare.

The fact remains that the coronal origin of solar flares and their magnetic nature are directly related. This means that for a better development of forecasting, it will most likely be necessary to link both methods together.

The brightest luminary of our system, despite its relatively calm life, still excites scientists. From time to time, storms and flares are observed on the Sun, as a result of which a huge amount of energy is released. For several decades, astronomers have been observing solar activity, but all the same, these processes remain a mystery to them.

What is a solar flare?

Being the brightest, and therefore the hottest star, the Sun, its surface is exposed to various space phenomena. Spots, solar torches, and storms can appear on it. But a solar flare is a rather interesting and unusual phenomenon. This is a very strong process, as a result of which a huge amount of different kind energy: thermal, light, and also kinetic. All this energy escapes during the flash, the solar plasma heats up, and the speed of its radiation can reach the speed of light.

Naturally, all these processes are reflected on the Earth. A solar flare rarely goes unnoticed, affecting both the atmospheres of other planets and the Earth's atmosphere.

Types of outbreaks

Scientists have identified five classes of this solar activity: A, B, C, M and X. Depending on the class, the amount of energy ejected and the speed, these categories are assigned the corresponding numerical value. For example, the most powerful solar flare was recorded by astronomers in November 2003. She was assigned class X28. During this process, sensors on one of NASA's satellites were damaged.

During a Class X flare, our planet may experience interference in radio signals and satellite broadcasts. In addition, magnetic storms can continue for several days.

During M-class flares, weak magnetic storms are observed, as well as interruptions in signals, mainly in the polar regions. All other outbreaks do not cause significant harm to our planet and are visible only in the Earth's atmosphere.

Causes

Why there is an outbreak on the Sun, scientists have been discussing for quite a long time. The thing is that spots appear and disappear on the surface of the luminary. They have a different magnetic polarity, so when the spots come into contact with each other or begin to somehow interact, magnetic flashes occur on the Sun.

The strength of such phenomena is determined by the area of ​​the glow, and it, in turn, is clearly visible on a special spectroscopic telescope. It is with this apparatus that they observe solar activity in general, and storms and flares in particular.

The power of the sun

Solar activity has been observed for about 40 years. During all this time, there were approximately 35 outbreaks of category X7 and above. In total, over 11 years of the solar circle of activity, a little more than 37 thousand flares are observed.

Scientists have recorded the strongest flares on the Sun. One of these occurred in 1859, later called the "great magnetic storm." During this period, very bright northern lights were observed on Earth, in almost all corners. In addition, telegraph devices were out of order, communications were disrupted.

The earliest strong outbreak is considered to be the so-called "superflare", which occurred in 774. Scientists have been analyzing and tracking for a long time solar system before reaching such conclusions. It is believed that after this outbreak, the Earth was affected by radioactive and UV waves that traveled fast enough to enter the earth's atmosphere and cause damage.

IN Lately a powerful outbreak was recorded in November 2003, but its activity did not have a detrimental effect on technology or people's health.

Consequences of outbreaks

Weak solar activity does not bring practically any significant changes on planet Earth. Most often, solar emissions simply do not reach our atmosphere. But if the release is strong enough, it can be dangerous. Flares have a particularly strong impact on the safety of those who are currently in orbit. Satellite communications may also change or be interrupted.

In addition, solar activity can provoke magnetic storms. Solar flares create powerful plasma emissions that reach our planet in about 2-3 days, come into contact with the Earth's atmosphere and ionosphere, as a result of which magnetic storms are formed. This phenomenon is quite safe, although it can affect the well-being of weather-dependent people.

In such people, magnetic storms cause an increase in pressure, resulting in headaches. A person feels weak and broken, but after a while this weakness passes.

How to improve well-being?

Since about half of the population of our planet is affected by geomagnetic storms, doctors have developed recommendations to survive the "stormy days" relatively calmly.

1. If you are weather sensitive, learn daily about the possibility of magnetic storms to be prepared for them.
2. Keep necessary medications close to you. For hypertensive patients - lowering pressure, for hypotensive patients - increasing. Those who suffer from headaches should stock up on migraine medications.
3. accept various water procedures - cold and hot shower, swimming. This will strengthen your circulatory system, reduce the risk of deterioration. On magnetic days, it is recommended to take a bath with sea ​​salt and essential oils.
4. On the eve of geomagnetic storms, avoid eating high-calorie meals, excessive consumption of coffee, spicy and salty, and generally overeating.
5. It is undesirable to be too nervous on such days. Stock up on positive emotions.
6. If you suffer from headaches, learn acupressure techniques. It will be useful not only on days of solar activity, but always when a migraine pesters.
7. On days of magnetic storms, a regular fridge magnet will help. It is enough to pass it over the body and head, and you will improve your health by changing the charge of blood cells.

Study of solar activity

To prevent deterioration in the condition of the population, to warn of possible failures of satellite signals and other negative consequences solar flares, astronomers and study the activity of the star. After all, if talk about the fact that processes on the Sun affect a person’s well-being remains just talk, then the impact of these processes on work various devices scientifically proven.

As a result of the studies, the so-called 11-year solar cycle was discovered. As a result of this teaching, it is proved that every eleven years the activity of the luminary can be repeated. In addition, these processes may be influenced different planets solar system.

Before the first telescopes appeared, solar activity was also studied. But the study was based on observing the luminary and the auroras with the naked eye. It has been proven that these phenomena are directly related to the processes occurring on the Sun.

IN present time It has also been proven that solar activity significantly affects weather on the entire planet: warming or cooling, tides, changes in the level of rivers and lakes, the occurrence of atmospheric fronts, the number of thunderstorms and the amount of precipitation.

Some studies show that changes in the number of insects or some animals, as well as fluctuations in human vital signs, are directly dependent on the activity of the Sun. But all these hypotheses are under study.

As a result of studying processes on the Sun, everything that happens on the surface of the star is recorded. A photo of a solar flare helps to examine in more detail the strength of the explosion and the speed of the plasma.

Instead of an epilogue

As you can see, solar activity is partly related to the life and health of every living being, normal operation technical systems. Therefore, such a phenomenon as a solar flare is being studied in space centers and observatories. The explosion of the Sun, as some scientists call it, does not pose a clear threat to the Earth. At least for the next few billion years, after which a powerful flash can occur, and the star will cease to exist.

More than a hundred years ago, scientists determined that the activity of our luminary directly affects many processes occurring on the planet, including human health. One of the most significant phenomena is flares that regularly occur on the surface of the Sun.

Why solar flares happen

Like other stars, our luminary is a huge ball of hot gas. This substance revolves around an invisible axis, but according to somewhat different laws, in contrast to solid bodies. Different areas of the star have different speed rotation. At the poles, this movement occurs at a slower speed, and at the equator, rotation is faster. In the process of rotation, the magnetic field of the star twists in a special way and rises above its surface, dragging the hot plasma with it. In such places, activity increases and outbreaks form.

In other words, the rotational energy of the star is converted into a magnetic state. Flares are places where a particularly large accumulation of such energy is released. It is easier to imagine this process if you remember how it glows ordinary lamp incandescent. When too great importance mains voltage, the lamp will burn out.

During the outbreak, a huge amount of energy is released. Any such flash is equivalent to the explosion of a billion kilotons of TNT. This amount of energy exceeds the energy of all known on given time fuel reserves on our planet at the same time.

The flash causes plasma clouds to form, which are directed towards our planet under the influence of the solar wind. This process causes geomagnetic disturbances called storms. They have a strong impact on everything on the planet.

What threatens solar flares

Under the influence of the mass of solar particles rushing from the surface of the sun to the Earth, the Earth's electromagnetic field is deformed, which causes a magnetic storm. At the same time, the amount of energy sent in the direction of the Earth and the impact exerted by it directly depend on the size of the flash.

Scientists have determined that natural disasters and cataclysms are associated with periods of solar activity. It was found that most often typhoons, earthquakes and hurricanes are formed just during the period of activity of the star. Based on the periodicity of outbreaks on the star, forecasts of natural disasters are built.

The negative impact is also on technology. After solar flares, the quality of communication deteriorates to a large extent, space navigation equipment often breaks down. There are failures in the functionality of aircraft, satellites and GPS navigation.

Solar flares are especially dangerous for astronauts if they are in the open space of space at that time. Under the influence of the most powerful flow of proton particles, the level of radioactive impact increases many times over. The atmosphere protects the inhabitants of the planet from its destructive effects. Astronauts are deprived of such protection and can be exposed to the strongest radiation. A similar charge of radiation, but to a lesser extent, is received by passengers in jet aircraft.

But solar flares also have pleasant phenomena, for example, residents northern latitudes can admire the beautiful polar lights. With especially strong outbreaks, it can also be observed in more southern regions.

How solar flares affect humans

The consequences of the increased activity of the Sun to one degree or another are felt by all residents. But to a greater extent, weather-dependent people and some age groups suffer from it:

• Children in the days of activity of the luminary become especially nervous and whiny, often capricious. It is in this way that destructive rays affect the emotional state of babies. On such days, immune defense decreases, which can cause the development of a variety of diseases. On such days, children need to be given vitamins, fruits and plenty of water.
• Elderly people feel activity by worsening heart activity. This condition is especially dangerous with high blood pressure. Solar activity impairs coronary circulation, increases the concentration of cholesterol in the blood. The correct action at such moments is to take an aspirin tablet, which thins the blood. In addition, this medicine will relieve pain. People who have had strokes, heart attacks, patients with ischemia and arrhythmia should keep the drugs prescribed by their doctor within reach.
• Motor vehicle drivers are also at risk. The fact is that the activity of the luminary affects increased fatigue, loss of concentration and attention. As a result, all reactions of a person driving a motor vehicle become slower. Therefore, it is best not to drive on such days, but if possible, spend it at home.

Solar activity affects not only the physical health, but also the mental well-being of a person. Even absolutely healthy people experience increased nervousness, excitability and aggression on such days. Other people quickly get tired, fall into depression. Emissions of solar energy cause exacerbation of diseases. In this case, the relapse continues after the end of exposure to the outbreak for several more days.
