I’ve done this in the past and it works, briefly.

It’s about blood flow. Your nose is not only filled with mucus, it’s also inflamed. Prioritizing blood flow to other parts of your body will temporarily alleviate that swelling, allowing you to breath again. Light exercise works just as well.

It helps with my lower back pain, it feels like I’m just floating afterwards, like my spine has liquified. Orgasms in general just help make the pain go away, sex is better, but I’ll take what I can get.

Tbh, If I’m feeling sick especially if it involves sinus congestion, I’m generally feeling far too icky to want to do that

For post-nut clarity. A genuine reason why my problem solving skills improve when I work from home.
