Goosebumps make humans warmer by trapping an insulating layer of air against the skin.

CONTESTED PARTIAL
Recorded sources
2 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Goosebumps make humans warmer by trapping an insulating layer of air against the skin?

Partly. Sources partially support the mechanism: arrector pili contraction increases air trapping and thermoregulation, and in furry animals this traps an insulating layer. However, one source states the reflex is not actually important in humans, so the claim that goosebumps make humans warmer is only partly covered and contested.
