Cold weather is the primary cause of hypothermia. When your body experiences extremely cold temperatures, it loses heat more quickly than it can produce it. Staying in cold water too long can also cause these effects. The inability to produce adequate body heat is extremely dangerous.
An abnormally low body temperature (hypothermia) can be serious, even life-threatening. Low body temperature may occur from cold exposure, shock, alcohol or drug use, or certain metabolic disorders, such as diabetes or hypothyroidism. A low body temperature may also be present with an infection, particularly in newborns, older adults, or people who are frail.
