👨🏿‍🔬 Goosebumps are a universal physical phenomenon induced by thrills and chills. The hair-raising experience is a result of adrenaline-stimulating minuscule muscles that pull at the roots of our arm hairs — in turn, making us bristle with bumps. This happens when we’re cold when we’re emotional, and according to a pre-print paper released in PeerJ, when some people just feel like it.⁠ ⁠ The ability to create goosebumps at will is called “voluntary piloerection.” It is very rarely documented: There are only three single-individual case studies published about people with this talent, and scientists don’t have a clue how to explain it.⁠ ⁠ ____⁠ ⁠ 📹 courtesy of: @obed.canario⁠ ⁠ ⁠ ⁠ #science #goosebumps #goosebump #phenomenon #naturalphenomenon #sciencefacts #scienceisfun #natural #adrenaline #thrill
