Thunder is a sudden and strong discharge of electricity between clouds or between clouds and the earth, followed by a flash (lightning) and a strong crash, a bang (thunder). People who are in the open under a lonely and tall tree at a time of storm and thunderstorm are in danger of being struck by lightning. Mortality from lightning strikes is 10-30%, and 50-70% of survivors have significant disorders, most often of the central nervous system.
Lightning strikes can be direct (when a person carries metal objects outdoors during thunderstorms) and indirect (when a one-way current passes through a tree, which has greater resistance than air from between the tree and the victim, so the current finds a path of less resistance. , and crosses into the ground).
The symptoms and signs of lightning strikes are the same as for electric shocks. The principles of first aid are the same.
