Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce it, causing a dangerously low body temperature, typically below 95?F (35?C). Normal body functions rely on a core temperature of around 98.6?F (37?C). As your core temperature drops, your nervous system, organs, and heart cannot function properly, leading to confusion, shivering, and potentially cardiac arrest.

Hypothermia is an extreme medical emergency. If you suspect someone has hypothermia, you need to call 911 immediately. While waiting for help, gently move the person to a warm, dry place, remove any wet clothing, and cover them with dry blankets or coats. In conscious patients, offer warm (not hot) non-alcoholic drinks. Do not massage them or apply direct heat, as this can cause heart rhythm issues.
The best way to beat hypothermia is preparation. Wear layers of warm, dry clothing when exposed to cold, and cover your head and hands. When exerting yourself in the cold, avoid sweating, as wet clothes cool the body rapidly. Educating family and friends about the early signs (like uncontrollable shivering) is vital for quickly recognizing and addressing the danger.
Hypothermia is a critical emergency. If a core body temperature drops below $95^\circ ext{F}$ ($35^\circ ext{C}$), call 911 immediately. While waiting for professional help, focus on stopping further heat loss by removing wet clothes and covering the person with dry blankets or coats. Never use direct, harsh heat.
Can you get hypothermia indoors?
Yes. While less common, hypothermia can occur indoors if the environment is very cold, such as in an unheated room or if clothing is wet for a long time. It poses a risk to infants and the elderly.
Is it safe to drink alcohol in the cold?
No. Drinking alcohol causes your blood vessels to dilate (widen), giving a temporary feeling of warmth but actually causing your body to lose heat even faster, greatly increasing the risk of hypothermia.
Does shivering use up a lot of energy?
Yes. Shivering is your body’s automatic way of generating heat through muscle activity. It can increase your body’s heat production significantly but uses a lot of energy, which is why shivering stops in severe hypothermia when the body's energy reserves are depleted.
