alalämpö

Alalämpö, also known as hypothermia, is a medical emergency that occurs when the body loses heat faster than it can produce heat, causing a dangerously low body temperature. The normal human body temperature is around 98.6 degrees Fahrenheit (37 degrees Celsius). When body temperature drops below 95 degrees Fahrenheit (35 degrees Celsius), it is considered hypothermia.

The most common cause of hypothermia is exposure to cold environments without adequate protection. This can include prolonged exposure to cold air, water, or snow. Other factors that can increase the risk of hypothermia include inadequate clothing, being wet, consuming alcohol or certain medications, and certain medical conditions. Infants and the elderly are particularly vulnerable to hypothermia due to their body's reduced ability to regulate temperature.

Symptoms of hypothermia can vary depending on the severity. Mild hypothermia may include shivering, confusion, and slurred speech. As hypothermia progresses, shivering may stop, and symptoms can include drowsiness, loss of coordination, weak pulse, and shallow breathing. Severe hypothermia can lead to unconsciousness and can be fatal if not treated promptly.

Treatment for hypothermia involves rewarming the body gradually and safely. This can include moving the person to a warm environment, removing wet clothing, and covering them with blankets. In more severe cases, medical professionals may use warm intravenous fluids or other methods to raise body temperature. Prevention is key and involves dressing in layers, staying dry, and avoiding prolonged exposure to extreme cold.
