when you get too hot :

  • hairs lie flat.
  • lots of sweat is produced- when it evaporates it transfers heat from you to the environment, cooling you down.
  • Blood vessels close to the surface of the skin widen (vasodilation). This allows more blood to flow near the surface, so it can radiate more heat into the surroundings.
  • You can take off layers of clothing to help you cool down

If you're exposed to high temperatures you can get dehydrated and you could get heat stroke. This can kill you.

What happens to your body when it gets too hot?

Your brain recieves signals from your skin receptors that tells your brain that your temperature is too hot. You produce sweat from your sweat glands, which cools your body down. The hairs on your arms lie flat against your skin so that no hot air can be trapped there. Your capillaries that are near the surface of your skin dilate/get widen so that more blood can get to the surface and so that more heat can be lost.

Why is a high fever dangerous?

The cells in your brain are called neurons. The White Matter of your brain is composed of neurons that have a myelin sheath on them (this makes the impulse travel faster). The myelin sheath is made up of lipids (fats). Fat melts when it gets hot. So, essentially, if your brain gets too hot, it will melt. That would be bad.
