goosebumps Goosebumps occur when the tiny muscles in our skins hair follicles pull hair upwards. It is an involuntary response meaning that we do not have control over this action. Unfortunately there is no beneficial function for getting goosebumps. What is important to remember is that it is most likely to show up when you're cold or experiencing strong emotions like excitement, shock or sexual arousal.

Chemical signals (neurotransmitters) from the sympathetic nervous system are the alarm that wake up these stem cells. Cold temperatures trigger the release of the neurotransmitter norepinephrine. Norepinephrine, also known as noradrenaline, contracts the tiny muscle attached to the hair follicle and also jolts the stem cells into action. The arrector pili muscle forms the bridge that brings the nerve cell endings into close contact with hair follicle stem cells. This makes goosebumps
