Body temperature

Body temperature is a measure of the human body's ability to generate and get rid of heat. The body is very good at keeping its temperature within a safe range, even when temperatures outside the body change a lot. When the body becomes too hot, it can sweat to cool off. When the body becomes too cold, it can shiver to warm up.

Normal body temperature

A normal body temperature for a healthy adult is typically around 98.6 degrees Fahrenheit (37 degrees Celsius), but can vary depending on the person, the time of day, and the weather. It can be influenced by numerous factors, including age, sex, time of day, and activity level.

Regulation of body temperature

The body regulates its temperature through a process called thermoregulation. This is primarily controlled by the hypothalamus, a part of the brain that functions as the body's thermostat. The hypothalamus receives signals from sensors in the body that detect temperature. If the body's temperature starts to rise or fall, the hypothalamus sends signals to different parts of the body to bring the temperature back to normal.

Abnormal body temperature

Abnormal body temperatures can be a sign of illness. A fever is when the body's temperature is higher than normal. This can be caused by infection, among other things. Hypothermia is when the body's temperature is too low, which can be dangerous and even life-threatening.

Measurement of body temperature

Body temperature can be measured in several ways. The most common way is to use a thermometer. Other methods include temperature-sensitive strips that are placed on the forehead, and electronic devices that measure the temperature of the ear canal or forehead.
