The area of your brain that controls body temperature is called the hypothalamus.
A) When the hypothalamus senses a rise in temperature, the body responds by activating cooling mechanisms such as:
- increasing the activity of sweat glands resulting in a cooling effect
- arterioles in the skin dilate allowing for skin capillaries to fill with blood. Heat is lost from the capillaries by radiation in order to cool you down
B) When the hypothalamus senses a drop in temperature, the body responds by activating warming mechanisms such as:
- constricting skin arterioles so that blood is diverted to deeper organs and tissues so that less heat is lost through radiation
- stimulating skeletal muscles to begin shivering. This generates body heat and has a warming effect

The body regulates its core temperature through processes like sweating, shivering, and adjusting blood flow. Sweating cools the body by evaporative heat loss, while shivering generates heat through muscle contractions. Blood vessels can dilate to release heat or constrict to retain heat, helping to maintain a constant core temperature.

How long can sperm stay fertile in room temp?
Sperm can remain fertile outside the body for up to about 1 hour at room temperature, but this can vary depending on factors such as humidity and exposure to light. It is best to keep sperm samples at body temperature (around 98.6°F or 37°C) if they need to be preserved for longer periods.
What could be the cause of low body temperature in a human?
Low body temperature in humans can be caused by factors such as exposure to cold temperatures, certain medical conditions like hypothyroidism or Addison's disease, medication side effects, severe infections, malnutrition, or alcohol or drug use. It is important to seek medical attention if a consistently low body temperature is experienced.
Why do you need lots of water?
Water is essential for numerous bodily functions including regulating body temperature, aiding in digestion, transporting nutrients, and eliminating waste products. It also helps maintain healthy skin, joints, and overall hydration levels in the body. Drinking enough water is crucial for supporting overall health and well-being.

Why is head cold and body hot?
Each area of the body dissipates heat at different rates in order to keep a constant temperature. This is because the enzymes in your body (that catalyse with other substances to create everything your body needs to go on) are very sensitive to temperature (which is the quantum movements of atoms). Your head and body may not be the same temperature externally but that is because they are regulating your internal body temperature to keep a core constant.
