What's the hypothalamus where is it, and what does it control?
~Another word for hypothalamus is homeostasis.The hypothalamus is a region of the brain that controls a number of physical functions. It is located in the middle of the base of the brain, and "shortens" the ventral portion of the third ventricle. The hypothalamus gland regulates body temperature, blood sugar, water balance, fat metabolism, feeding habits, sleep, sexual behavior, emotions, hormone productions, and the autonomic nervous system. It directs the "fight or flight" response of the autonomic nervous system. Fear or excitement causes signals to travel to the hypothalamus, which triggers a rapid heartbeat, faster breathing, widening of the pupils, and increased blood flow. The hypothalamus can be regarded as the thermostat controlling the temperature of the body. It initiates shivering and contraction or expansion of blood vessels. The hypothalamus triggers behaviors such as putting on or removing clothes, turning on the heat, or moving into the shade.It also regulates other glands such as thyroid, pancreas, ovaries etc. This amazing gland takes up less than 1% of the brain.

Usually normal body temperature is affected when there is an infection in the body and the white blood cells go into overdrive trying to fight it off, this causes a rise in body temperature. Also even though we are warm-blooded temperature over long periods of exposure can also affect body temperature.

temperature rise and fall is rare. if you're in a cold place, you're body temp is still 98 as normal it's just how you feel and think.
