James Daniels, a follower of the paleo diet, has published Paleo Sleep, which purports to tell readers how to sleep like a caveman.

“In a nutshell, my program teaches you how to sleep like a caveman, which in the modern day means getting a good, solid, refreshing night’s sleep every single night,” Daniels says on his site.

The digital book contains a six-step paleo sleep formula, plus eight chapters sharing the author’s research on optimizing the natural sleep-wake cycle.

Vlad Barman from the site HealthReviewCenter.com says in a release, “Paleo Sleep book is a useful book for those people who want to learn how to get rid of a bad night’s sleep. This book can help people improve their sleep quality, live longer, and generally feel happier.”
