Why does exhaling, after you’ve held your breath for a long time, feel like you’re not suffocating.

When you hold your breath to the maximum your body will allow, be it underwater or just in air, you can gain a few seconds extra by slowly releasing your breath. It will feel better and your body won’t react like it is suffocating while you are doing it. Why does this happen? We’ve all tried to hold our breath for as long as we can. We take a huge intake of air and then hold it as much as we can. But, when you breathe out slowly the “air” that’s in your lungs, you don’t feel like you are going to suffocate while doing it. In fact, it’s almost like a great relief. Why is that?

Your body can’t really detect a lack of oxygen, what it detects and and drives your urge to breathe is an excess of CO2
