How does the brain control body temperature? Explain.
Answers
Answer:
Sweat gets a bad reputation, even though it plays an important role in cooling down our bodies when we get too hot. But how, exactly, does your body know when to start sweating? It knows because a part of your brain, called the hypothalamus, tells it to. All humans and many animals have a hypothalamus.
The hypothalamus does many things, but two of its most important jobs are to maintain homeostasis and to control certain hormones. Homeostasis is very important to all animals, including humans. If we look at the word, we see that homeo means “the same”, and stasis means “not moving”, or “holding”. So homeostasis means that something is held at the same place.
Let’s think about homeostasis in terms of body temperature. Most animals maintain, or hold, their temperature at a certain level. For humans, this is about 98.6°F (37°C). When your hypothalamus senses that you’re too hot, it sends signals to your sweat glands to make you sweat and cool you off. When the hypothalamus senses that you’re too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis. The hypothalamus also maintains homeostasis in lots of other ways, such as by controlling your blood pressure.
The temperature in your body, like the temperature in your home, is a balance between different cooling and heating systems.

The hypothalamus also controls many of your hormones. It does this by being a sort of gatekeeper for other glands that release hormones. When your hypothalamus senses a change in your body, it will tell the right gland how to help correct that change.
For example, when you have too much homework and are stressed out, the hypothalamus will send a signal to your adrenal glands and they will release hormones that can help your body deal with the stress. For the stress response, this will result in the release of sugars, which will help to power you through your homework. The hypothalamus is also involved in the release of many other hormones that control everything from your blood pressure to how much you grow when you’re young. This makes the hypothalamus the main link between the brain and your hormonal, or endocrine, system.

This is a very simple explanation of this question.
Hypthalamus also known as the body's thermostat , is apart of brain which secretes hormones to control things like hunger , thirst , body temperature ,etc
We have a constant body temperature of 37°C. Brain helps to maintain temperature in body this way.
