➡️Goosebumps are the result of tiny muscles flexing in the skin, making hair follicles rise up a bit. This causes hairs to stand up. Goosebumps are an involuntary reaction: nerves from the sympathetic nervous system — the nerves that control the fight or flight response — control these skin muscles.

➡️Goosebumps occur when the arrector pili muscles cause the hairs to stand up, making the skin look bumpy. When the hairs stand up on the skin, it is known as piloerection. The arrector pili are smooth, involuntary muscles that a person cannot voluntarily contract. Hence, people cannot voluntarily cause their goosebumps.
