Breath responds to Smells

Breathing is not just about oxygen, it's also how we receive odors which contain important sensory information.

When we encounter a rotten smell like decomposting eggs or a dead rat, we automatically start to breathe fast and shallow. This is because our body is trying to invoke the 'flight' response so that we move away from this potential threat (bacteria or nearby predators).

On the other hand, scents like roses or fresh bread leads to slow, long breaths (inviting you near the smell).
