![]() ![]() ![]() This is one of the first warning signs of hypothermia. When hypothermia sets in, the shivering stops as your body is now trying to conserve energy. When your body is cold, you try to protect yourself by shivering. Hypothermia can come on very slowly, making it difficult to notice that it's happening. People taking beta-blocker medications such as propranolol* and metoprolol may also have a higher risk of frostbite. Extreme cold, a wind-chill factor, altitude, and lack of proper protective clothing all contribute to quicker freezing of the skin. These cases often involve fishermen who have fallen into the water.įrostbite is caused when body parts, usually fingers, toes, noses, and ears, are frozen. Many lakes never get very warm and swimmers who stay in cold water for too long can become hypothermic. Hypothermia can also happen in the summer. You're at risk if you're not adequately dressed for the cold, if you're outside longer than you'd planned or you can't move, if you fall into near-freezing water, or if your clothing gets wet.Įvery winter, some seniors die from hypothermia in their own homes because they can't pay for adequate heating or their heating systems break down and they can't get repairs done. Hypothermia can occur in a number of situations, most often where extremely cold weather is a factor. Smokers and people with diabetes and other circulatory problems have a higher risk of developing frostbite. Mild frostbite doesn't leave lasting damage, but severe frostbite does cause permanent damage and may even require amputation of a body part. It happens most often to the hands, feet, nose, and ears. Their below-normal temperature slowed down their brain function and caused their bodies to use less oxygen.įrostbite happens when a part of the body actually freezes. There are cases where children who have fallen into freezing water were successfully revived even when there was no heartbeat. In some rare cases, though, hypothermia can save lives. When the body becomes very cold, all physiological systems begin to slow down – eventually to the point that threatens survival. Young babies (because they have a greater surface area to body weight ratio) and seniors are the most vulnerable to developing hypothermia. Hypothermia is defined as a drop in body temperature below 35☌ (95☏). Normal body temperature is around 37☌ (98.6☏), as measured by mouth. Hypothermiaoccurs when you have abnormally low body temperature. ![]()
