Goosebumps when sunburnt occur as a response to pain and irritation from the damaged skin. The body reacts by stimulating the tiny muscles at the base of hair follicles, causing them to contract, which results in the characteristic bumps. This reflex is part of the body's defense mechanism to protect and soothe the affected area. Additionally, it might be linked to the body's attempt to regulate temperature in response to the heat from the sunburn.
