Name 3 jobs that hair on your body does?

Here are three functions that body hair serves:

1. Insulation: Hair helps regulate body temperature by providing a layer of insulation. This is especially important for humans who live in cold climates, as hair can help retain heat and prevent the body from losing too much warmth.

2. Protection: Hair can provide a physical barrier that helps protect the skin from damage, such as scratches and abrasions. This is particularly important for areas of the body that are exposed to a lot of friction or wear and tear, such as the scalp, eyebrows and eyelashes.

3. Sensory function: Hair follicles contain nerve endings that help us sense our environment. For example, the hairs on our arms and legs can help us detect changes in air currents or objects that brush against our skin.
