Hypothermia is a medical condition that occurs when the body's core temperature falls below 35 degrees Celsius (95 degrees Fahrenheit). Normally, the body maintains a temperature around 37 degrees Celsius (98.6 degrees Fahrenheit), but in hypothermia, the body loses heat faster than it can produce it. This causes the body's systems, including the heart, nervous system, and organs, to function poorly, potentially leading to serious complications or death if untreated. The condition can happen in cold weather or when exposed to cold water, but it can also arise in cool environments if a person is wet or unable to warm themselves. Symptoms include shivering, confusion, slurred speech, slow breathing, weak pulse, clumsiness, and loss of consciousness. The body tries to respond by shivering and redirecting blood to the core, but if these measures fail, hypothermia worsens. Hypothermia is a medical emergency requiring immediate treatment to warm the body and prevent further heat loss. It can affect anyone but is more common among older adults, children, people exposed to cold environments for extended periods, and those with medical conditions or intoxication that impair temperature regulation.
