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.
Hypothermia happens when your body temperature drops way below normal, causing the circulatory, respiratory, and nervous systems to slow down. Normal body temperature is around 98.6 Â°F (37 Â°C). Hypothermia happens if your temperature drops to 96 Â°F (35.5 Â°C) or below. Hypothermia often happens gradually, but it can happen within minutes, such as if someone falls through the ice into cold water. Then your body starts to lose heat faster than it can produce it.
