The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [8][9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation), what part of the body the measurement is taken at, state of consciousness (waking, sleeping, sedated), and ...

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...
Jul 30, 2023 · 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 human body's thermostat is the hypothalamic thermoregulatory center, which, more specifically, is located in the preoptic area of the hypothalamus.

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.

Jan 6, 2023 · During pregnancy, a person’s basal metabolic rate (BMR) is higher. This means the body produces more heat. One study found that body temperature peaks at 96–99.5°F (35.6–37.5°C) around the ...

Dec 6, 2022 · A body temperature of 38°C (100.4°F) or more is considered to be a fever in adults. Temperatures above 39.5°C (103.1°F) are considered to be a high fever, and very high fever is defined as any temperature above 41°C (105.8°F). A temperature between 37.5°C and 38°C is an elevated body temperature. Children are considered to have a fever ...

Sep 4, 2023 · The normal temperature of the human body is approximately 37 degrees Celsius (C), or 98.6 degrees Fahrenheit (F), and varies by about 0.5 C throughout the day. This variation in the core body temperature results from normal physiological processes throughout the human body, including metabolic changes, sleep/wake cycles, hormone variability, and changing activity levels.
