- Body temperature must be controlled within a very narrow range so that the body can function properly. In particular, enzymes in a body's cells must have the correct temperature to be able to catalyse chemical reactions. Extremes of body temperature are dangerous: high temperatures can cause dehydration, heat stroke and death if untreated

Extreme weather can significantly affect the body’s ability to regulate temperature. Hypothermia occurs when a person has exposure to extremely cold temperatures for an extended period. In these instances, the body loses heat quickly, and heat production cannot keep up, causing a dip in body temperature. In addition to freezing temperatures, hypoth...
When a person has an infection, harmful microorganisms invade the body and multiply. These pathogens can thrive at typical body temperatures, but an increased temperature makes it more difficult for some of them to survive. For this reason, part of the immune response to infections is often a fever. This occurs when the body raises its own temperat...
Infants and older adults have a higher riskTrusted Sourceof thermoregulation disorders. The reason for this is that these individuals have a lower muscle mass, a decreased shiver reflex, and lower immunity. Older adults tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness. Sometimes, they ...
Certain medications can disrupt thermoregulation as a side effect, causing a temporary rise in body temperature. Some people refer to this as “drug fever.” Examples of medications that can have this effect include: 1. antimicrobials, such as antibiotics 2. nonsteroidal anti-inflammatory drugs (NSAIDs) 3. first generation anticonvulsants 4. antidepr...
Sep 12, 2023 · Why body temperature — and changes over time — matter. Body temperature is vital to health; that's why it's among the "vital signs" — along with blood pressure, heart rate, and breathing rate — routinely checked by your doctor.

Jul 30, 2023 · Thermoregulation is the maintenance of physiologic core body temperature by balancing heat generation with heat loss. A healthy individual will have a core body temperature of 37 +/- 0.5°C (98.6 +/- 0.9°F), the temperature range needed for the body's metabolic processes to function correctly.

The optimal temperature of the human body is 37 °C (98.6 °F), but various factors can affect this value, including exposure to the elements in the environment, hormones, an individual’s metabolism, and disease, which can lead to excessively high or low body temperatures. Body temperature is regulated mainly by the hypothalamus in the brain.

Oct 18, 2022 · Thermoregulation refers to how the body maintains its internal temperature. If your body temperature becomes too cold or hot, it may lead to severe symptoms and even death.
Dec 6, 2022 · A healthy body functions best at an internal temperature of about 37°C (98.6°F). But everyone has their own individual "normal" body temperature, which may be slightly higher or lower. Our bodies also constantly adapt their temperature to environmental conditions.
