Solar flares - why they exist and how are they dangerous?

in hive-106951 •  4 years ago  (edited)

For more than a decade, scientists from different countries have been trying to figure out how to predict such natural phenomena as solar flares. Their frequency is determined by the eleven-year cycles of solar activity. However, the most powerful and unpleasant manifestations of the Sun's activity overtake us, quite suddenly, to this day. This is due to the fact that solar flares can be predicted only by analyzing magnetic solar fields that do not differ in constancy and at least minimal stability.

Solar flares are considered the most unfavorable for space explorers. Representing the greatest degree of threat in the vastness of outer space, waves of powerful explosive energy may well damage communication satellites, and even spacecraft, completely disabling devices and control systems. Solar flares , producing powerful proton fluxes, significantly increase the level of radiation, as a result of which people in outer space can easily be exposed to strong radiation. Even passengers on airliners who fly at certain times during peak outbreaks are at risk of radiation exposure.

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 beginning of a solar flare, radiation reaches the Earth's surface within an 8-10 minute period, after which powerfully charged particles are directed towards our planet. Then, 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 flash usually does not exceed several minutes, but this time and power of the energy release is quite enough to influence the state of the Earth and the well-being of its inhabitants.

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

The main hazards in solar flares

Without exaggerating at all 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 the negative effects of the energy explosions of the solar system.

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

  • Immunocompromised people;
  • Population suffering from cardiovascular diseases, migraines, surges (drops) in blood pressure;
  • People with chronic illnesses that are exacerbated by each solar flare 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 during magnetic storms, old wounds, scars, damaged bones or sore joints begin to worry many. Also, a separate group includes those representatives who have a so-called delayed reaction to magnetic storms. These are people experiencing negative effects a few days after solar flares.

Many experts advise to undergo periodic 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 impending malaise and deterioration of health, then at least to have effective medicines on hand .
