perpetrators of storms are spots appearing on the Sun, through which dispersed plasma particles fly out of the deep regions of the Sun. By noticing a spot on the sun’s surface, observers can fairly accurately calculate the time when heavy particles disturbing the calm of the geomagnetic field will reach Earth. As a rule, it is 1-2 days. By intensity, magnetic storms are assigned estimates on a ten-point scale. Magnetic storm season can be observed in months such as March, April, May, August, September and October. People who have a strong and steady own magnetic field hardly notice the negative effects caused by unstable geomagnetic conditions. Those whose field is weak and easily variable become the main victims of the storm. People sensitive to magnetic storms are divided into 2 groups: those whose well-being deteriorates directly at the moment of flash in the Sun and those who are later influenced by charged particles that reach Earth. During periods of geomagnetic disturbance, attacks and deaths increase among people suffering from cardiovascular and mental disorders. Hyper- and hypotonics, the elderly, are also at risk. In a negative way, storms also affect healthy people, who may experience a decrease in the speed of reaction and discernibility of light flashes, which is evident in the increase in the number of air and car accidents. During a magnetic storm, clots are formed in the blood, slowing blood flow and leading to heart rate disorders. Blood clotting causes headaches and dizzies. People often begin to show aggression and irritability. In order to minimize negative effects on the body, during a magnetic storm it is not recommended to engage in mental and physical activity.
