Question

: How do humans feel temperature differences and how precisely can we feel it?

In: Biology

Answer 1

You have special hot and cold receptors all over your body that react to the flow of heat into and out of your body. Unlike a thermometer, your receptors do not detect the actual absolute temperature, which is why metal and water at room temperature feel colder than the room temperature air.

The receptors can detect changes as small as .02 degrees Celsius on some parts of your body. Other parts are 100 times less sensitive.
