Hello, dreamers. One of our missions here at ProSomni Sleep Health and Wellness is to really educate people, not just on sleep, but on the restorative benefits of REM sleep and the importance of REM sleep to brain health. So that's what I explain in my book, Why We Can't Sleep: The Biological Secrets Behind Insomnia. I make sure every chapter is filled with a full understanding Of what actually happens in your brain when you can't rest. For instance, chapter 1, Sleep. I identified the necessity of sleep as a necessity of life. If you don't sleep, nobody sleeps, and nothing sleeps, or your brain. Chapter 2, Understanding Sleep. A foundational understanding of sleep 101. We weren't taught how to sleep. Until we can't. Chapter 3, the science behind sleep pressure and how adenosine sleep pressure plays a role in our inability to rest. Pick up my book today on Amazon, Why We Can't Sleep: The Biological Secrets Behind Insomnia, and help us educate you in getting better rest. Stay rested, my friends.
