We shiver to increase body temperature.

Front

By both shivering and getting goose bumps.

During childbirth, the release of oxytocin increases contractions, which further stimulates its release.

Front

How does the body respond to overheating?

The body responds by sweating and increasing blood flow to the skin.

Front
