Just as it is important for the body to cool itself in the heat, it must also warm itself when cold. Exercise brings about a warming effect, which, consequently, allows people to tolerate colder temperatures. However, particular body parts are susceptible to cold weather, especially the hands and head, which must be protected to avoid excessive heat loss. Drinking lots of water and fluids is the best way to combat dehydration. If untreated, heat exhaustion may lead to heat stroke.
Heat stroke requires immediate medical attention.
Frostbite occurs when body parts become frozen. Both frostbite and hypothermia require medical attention. Discuss physical activity risks related to other environmental factors. Sunscreen and sunglasses should always be used to protect the body from the sun's ultraviolet rays.
