Is it true that Goosebumps serve an evolutionary thermoregulatory function in human anatomy?

Yes. Goosebumps, or piloerection, serve a well-documented evolutionary function in thermoregulation by contracting muscles to trap a layer of insulating air near the skin across mammals.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked 4 Aug 2026

The analysis

Multiple retrieved papers explicitly confirm that piloerection (goosebumps) functions to provide thermal insulation by trapping air near the skin surface across mammalian species, including humans. There are no refuting papers.
