10 Symptoms of Hypothermia
Reviewed: Dr. Gromatzky
Symptom #3: Drowsiness
Our brains require a lot of energy to keep them active. This means a lot of food and oxygen and there is also a lot of heat involved. Our heads actually emit more heat than any other part of the body, mostly because of the intense activity going on in the brain. When we get too cold, though, then our brains can begin to slow down.
As the brain begins to slow down, then we too begin to slow down. We begin to feel drowsy as the brain is not as active as it usually is. Unexplained drowsiness can be caused by a wide range of potentially serious conditions so it should be taken seriously.
