AI Thread Summary
Lack of sleep can significantly impact the healing process of injuries, including minor ones like a hurt finger. Although innate immune cells are active at the injury site, sleep plays a crucial role in overall recovery. Research indicates that sleep, particularly delta sleep, is essential for various physiological processes, including immune function and tissue repair. The brain remains active during sleep, which is vital for healing, suggesting that adequate rest is necessary for optimal recovery, even for minor injuries.

Let's say you hurt your finger. If you lack sleep. Why would it affect healing of the finger? Is it not the innate immune cells in the fingers and blood work isolated there? Why would lack of sleep affect the healing of the finger? Remember when we sleep, our brain is still as active as when we are awake.

For minor injuries, the amount of sleep I would expect doesn't affect the rate of healing as few body resources are being utilized towards the repair.

Have you looked up sleep and injury?

No. Please do not make up explanations. Do a search on 'delta sleep' to see one reason why this statement is wrong.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
