Why does it hurt way more to stub/bang a finger against something when it’s cold out?
In: Biology
I just answered this 13 days ago, so make sure to use the search function.
When it’s cold out, our veins constrict to reduce the blood flow to our extremities, so we can keep more blood and heat by our organs. This makes the skin on our hands and feet and such tighten up, which causes pressure on our skin. It also causes the soft tissue in our body to swell, adding tension to joints and making us stiff.
This pressure, tension, and stiffness, combined with the fact that our nerves are already super sensitive in the cold, makes any ding, bang, snap, and sting hurt a lot more than it would when we’re warm.
