Why can’t we inhale and exhale at the same time?
In: Biology
The same reason we can’t inflate and deflate a balloon at the same time, or push and pull with one arm at the same time, jump and squat at the same time, close and open one hand at the same time. You just end up in this stasis of doing nothing because there are conflicting muscle groups firing at once.
Because inhaling is sucking air into your lungs and exhaling is expelling air from your lungs.
I assume you’re considering inhaling through your nose and exhaling through your mouth or vise versa.
Both your nose and your mouth are conected to the same lungs. so you cant blow and suck at the same time.
The closest thing we can do to that is called circular breathing, and a lot of professional musicians who play wind instruments can do it. I’ve never been able to but if you can you’re able to inhale at the same time as you can push air out to play your instrument. Some black magic shit if you ask me, but it’s possible.
How high are you right now?
Because your diaphragm can only do one thing at a time, move up or down. It can’t do both simultaneously.
Your mouth and your nose don’t actively push air through them. You inhale by pulling on your lung, which then sucks in air through your mouth or nose – whatever isn’t blocked or obstructed. When exhaling, you push on your lung, forcing the air out the same way. So, for lung breathing, the answer is: because the lung can’t extend and compress at the same time.
There are ways to have air flow in through your mouth and out of your nose at the same time, or vice versa. You can puff up your cheeks, and then blow the air out of your mouth while at the same time inhaling through your nose. Or you can put a source of pressurized air to your mouth (e.g. a balloon you’ve blown up before) and let the air stream into your mouth and out of your nose again. Whether that counts as “inhaling” and “exhaling” depends on your definitions.
The reason why we can’t inhale and exhale at the same time is because we create a pressure difference between our lungs and the atmosphere. We can only either breathe in or only breathe out due to this.
To breathe in, our diaphragm extends downwards making our air cavity bigger. The enlarged air cavity results in the pressure in the air cavity to be below that of the atmosphere. This causes air to rush into our lungs to make the pressure equal to the atmosphere.
To breathe out, the process is reversed. So, the diaphragm contracts which reduces the volume of the air cavity. This increases pressure to above that of the atmosphere and so the air in our lungs is forced out.
