Thermoregulation. Our body functions most eficiently at 37°C. The blood temperature is monitored by the brain and if it varies from 37°C, various changes are brought about. The means by which our body maintains a constant temperature is called thermoregulation.

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...
The human body needs to maintain a temperature at which enzymes work best, around 37°C. Processes such as respiration release energy as heat; and the body loses heat energy to its surroundings – the energy gained and lost must be regulated to maintain a constant core body temperature.
Study with Quizlet and memorize flashcards containing terms like Two main ways in which the body regulates body temperature?, What is the equation for heat production?, What are three ways in which heat can be lost? and more.
This lesson looks at how body temperature is controlled in humans through a homeostatic mechanism and includes details of a negative feedback loop. The lesson begins with a three pronged task where students have to use the clues to come up with the word homeostasis and the number 37 and then see if they can make the link in the human body.
