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

543 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’.

James Herriot (British vet) wrote about a seriously ill sheep that a farmer wanted put out of his misery. Dr. Herriot administered the euthanasia drug to the sheep in a remote shed and left the farm.

Dr. Herriot returned to the farm a few weeks later for something and the farmer pointed to a sheep peacefully grazing in the field and said “remember her?”

Apparently the sheep was out for a few days and for whatever reason not buried. When the farmer finally went to do that, he found her alive and well…

Dr. Herriot’s theory was that the sheep just needed a break from the pain so that her sleeping body could work on healing itself.
