Detailed explanation-1: -A layer of hair or fur even as thin as the hair on our arms can trap air and create an insulating layer between our skin and the colder temperatures outside. The thicker the fur and the oilier it is the better the insulation.
Detailed explanation-2: -The hair on our heads doesn’t just look nice. It keeps us warm by preserving heat. Hair in the nose, ears, and around the eyes protects these sensitive areas from dust and other small particles. Eyebrows and eyelashes protect eyes by decreasing the amount of light and particles that go into them.
Detailed explanation-3: -Hair serves as mechanical protection for the skin, increases sensory function, and aids in regulating body temperature. Arrector pili muscles located in the dermis attach to hair follicles, helping the shaft to stand and trap air close to the epidermis for temperature control.
