Eli5: Does shivering really help us warm up?

766 views

I’ve always been told that shivering/teeth chattering when cold is supposed to help our bodies warm up. However, I’ve never been in a situation where I’ve been cold enough to shiver and have also noticed a positive difference in my body temperature after the shivering started. So why do we still shiver if it doesn’t help all that much? Or does it help but in a way we cannot really feel?

It does help. Think of going for a run. afterward you are hot (and sweety). thats because you were using your musles and making them work.

Shivering is the same, your body makes fake work for your musles to do so they will make some extra heat.

You dont feel this because you dont really feal your own body tempetature very well (atleast not conciously), just the rate at which heat is leaving through your skin, which hasnt changed.
