Walker presents a compelling case for sleep as a the misunderstood aspect of our health, both physical and mental. With lots of data, he manages to make sleep studies and effects interesting. He covers most aspects of human health and how sleep is crucial to health in all areas. Most Americans are shortening their lives from disease or accident by getting too little sleep. I particularly enjoyed the sections on Alzheimer’s, hormones, cancer and aging.
This is a dense book and it took me awhile to get through it. (I checked in out of my library twice before buying it on Audible.) But I am glad I read it and it has made me prioritize sleep more.
