How does human touch work?
Why is skin important?
It covers all of our body, protecting it from getting hurt.
It helps us feel lots of things like cold, heat and pain.
If we are too hot it can help us cool down.
If we are too cold it can help us warm up.
Why are feet so ticklish?
- Our skin has things called 'receptors'. These help us feel touch.
- Different areas of the body have different amounts of receptors.
- The ticklish areas like feet have a lot of skin receptors!
