Hypothermia is a condition that is considered a medical emergency. Hypothermia sets in when the body starts to lose heat quickly but is not able to produce it fast enough. Typically the condition sets in when the body is exposed to cold weather or extreme low temperatures such as immersion in cold water.
As the temperature drops, important organs like the heart and other systems such as the nervous system stop working normally. If left untreated the condition may ultimately become fatal. Some of the symptoms that can indicate the setting in of hypothermia can include the following.
Shivering is typically the first sign of hypothermia. This is because shivering is the body’s automatic defense against cold temperatures in an attempt to warm itself.
Shivering is a natural body function in response to cold surroundings and temperatures where skeletal muscles start to shake in small motions trying to produce warmth. With the surface of the skin getting chilly, receptors in the skin transmit signals to the brain which instructs muscles to contract and expand in speedy bursts. This twitching exercise generates heat that helps raise body temperature.
