In humans, a constant internal temperature is maintained by the balancing of metabolic heat with loss to the environment. The primary control center is the hypothalamus in the brain. To increase body temperature in cold conditions, the body can:
- increase metabolism in the mitochondria of cells (a specialized form of fat called brown fat is used when available)
- trigger increased activity of the muscles (shivering)
- constrict the arteries near the skin surface
- stop the release of sweat
- contract hair follicles to raise body hairs, trapping a warmer layer of air along the skin
To decrease body heat in warm conditions, the reverse processes occur : decreased metabolism, vasodilation (flushing), increased sweating to cool by evaporation, and relaxation of the hair follicles to expose the skin to the air. Heat loss can also be increased from the lungs by opening nasal passages.

Which structures help maintain your body temperature?
Sweat helps maintain your body temperature, Whenever your sweat evaporates, it cools you down.
How does homeostasis impact the human body?
Maintain a normal value of certain body temperature.
Why do you sweat excessively?
to maintain our body temperature
How do bodies maintain homeostasis?
Organisms maintain homeostasis by perceiving changes in the internal and external environment and then signalling to cells, tissues and organs to counteract those changes. For instance, to maintain a constant internal body temperature, the body senses both the body's current temperature as well as the air temperature around the body. Then, depending upon which is warmer and which cooler, the body then signals for additional blood flow to the skin and the secretion of sweat (to cool the body) or signals for decreased blood flow to the skin and possibly for muscles to start contracting (to warm the body).

How does ear size help foxes maintain constant body temperature?
There are blood vessels in the ears that help maintain body temperature and the bigger the ear the more surface area it has to work with in order to regulate the temperature.
Which part of brain maintains body temperature?
Your brain helps your body to maintain a constant temperature by detecting temperature receptors that are found in the skin. Temperature is controlled by the hypothalamus.
