I can feel one side open up and immediately the other side is congested. I don’t understand. If your body can open up one side why can’t it open up both??
In: Biology
Because it doesn’t want to.
The body normally will periodically swell the tissue in alternating sides of the nose, switching the bulk of air flow between sides to give the other side a break. It allows it to rest and heal because if a side was always active it would likely dry out and have problems over time. By cycling back and forth they both get a chance to recover, but when you are sick this swelling can often mean that side is entirely blocked off.
