Here is the book that I’m recommending: Why We Sleep, unlocking the power of sleep and dreams by Matthew Walker, PhD
A great explanation of the scientific basis of sleep and why it’s so important. If there was one magic pill, it would be good quality sleep.
“Routinely sleeping less than six hours a night weakens your immune system, substantially increasing your risk of certain forms of cancer. Insufficient sleep appears to be a key lifestyle factor linked to your risk of developing Alzheimer's disease. Inadequate sleep-even moderate reductions for just one week-disrupts blood sugar levels so profoundly that you would be classified as pre-diabetic. Short sleeping increases the likelihood of your coronary arteries becoming blocked and brittle, setting you on a path of cardiovascular disease, stroke, and congestive heart failure. Sleep disruption further contributes to all major psychiatric conditions, including depression, anxiety, and suicidality.”
