How does our sense of touch work? There are tons of particles in the air but we can’t feel them. How does this work?
In: Biology
It depends…
You feel something when your nerve endings are triggered… This might be from pressure, heat, cold, or if something moves the hairs on your skin.
They can also be triggered by chemical means such as with capsaicin. You don’t have the same nerve density throughout your body as well, meaning you’re more sensitive in some parts versus others. Back of your hand vs back of your neck for example. Can you identify two close points touching your skin or does it feel like only one?…
It’s difficult to answer the question directly … for pressure it’s thought to be 1.2 lbs/in^2 or 0.85 g/mm^2 on the back of the hand.
