The Bedtime Scientist

A question

How does your sense of touch work?

A calm, true answer. Then, if the wondering keeps going, the whole episode.

The short answer

With millions of tiny sensors spread through your skin, each kind listening for something different: light contact, steady pressure, stretch, heat, cold, pain.

They send signals up the nerves, and the brain assembles them into one single feeling. Touch is the first sense to develop, before sight or hearing, and steady gentle pressure, like a tucked blanket, genuinely settles the nervous system.
