How / why does the human body rapidly heal during sleep ?

545 views

I’ve always been curious as to how the body seems to heal different issues primarily during sleep, for example I’ve had a few sebaceous cysts in my life and they’re always noticeably smaller when I wake up whereas while I’m awake I can’t generally tell if anything has happened at all. Or even say the dentist, had a few wisdom teeth pulled one tike and each consecutive day after sleep the pain / swelling has been reduced drastically.
I also have RA and most of the pain / swelling is always gone or reduced in the morning compared to the previous day / night ? In some sense it’s almost like my disease has been ‘reset’.

Thats what sleep is for , thats when your brain does poo and it goes to your blood system and its filtered.

Also pretty reasonable to heal shit when you are not moving like for example you work 8h maual labor and your muscles work all time , then u go sleep and body is getting repaired and making your muscles harder.

when you are awake and moving, most of the oxygen in your blood goes to your muscles. when you are sleeping, your body is still and your immune system can receive more oxygen allowing it to heal your cyst (which is an infection). this is why rest is very important when you are sick (have an infection).
