Eli5: if humans run at 37.5 degrees Celsius why do temperatures lower than that feel hotter?

Thinking about this while I sit in 20 degrees heat sweating my ass off. Like shouldn’t anything under 37 degrees feel cold to us?

We don’t feel heat by how hot it is.
We feel heat based on if our skin is gaining or losing heat.

Our body may have a warm internal temperature but your skin’s surface temperature is closer to ambient.

So if you encounter some hot air that warms your skin or a blanket that prevents your skin from losing heat as easily, your nerves sense any increase in heat energy buildup as “warm”.

Even if it’s just a few degrees warmer.
