I read a lot of books. Most are good, some are great, and few are life-changing. “Why We Sleep” by Dr. Matthew Walker is a life-changer.

I used to say that the book scared me into prioritizing my sleep. With time, I realize that it’s not that I am scared into sleeping better but rather it gave me permission to prioritize my sleep. While napping or going to bed early once seemed like a luxury, I now consider it more important than my workout or what I eat.

Public safety needs to start prioritizing sleep, not just as one of the pillars of health, wellness and safety, but as the foundation upon which everything else is built.

I have said it and I’ve heard it time and time again: “I’ll sleep when I’m dead.” Well, fun fact, research shows that not getting enough sleep will actually lead to a shorter lifespan than if you are well-slept! So, you will sleep when you’re dead, and eternal sleep will come sooner if you are not getting seven or more hours of sleep a night.

Walker’s book lays out all the health impacts of not getting enough sleep. Sleeping less than seven hours per night increases risks for nearly every disease – cancer, cardiovascular disease, mental health issues, fertility issues, obesity, hypertension, diabetes and suicidal ideation. These are all health challenges law enforcement officers struggle with, making it even more important for personnel to prioritize getting enough sleep.

For a scientist, Walker’s actually pretty funny – or as funny as a scientist can be. He walks you through the science of sleep, why it is so important, what happens when you sleep and what happens when you don’t.

The findings he reports are amazing and humbling all at the same time. He challenges a lot of assumptions and long-held beliefs with evidence. For instance, think you are just someone who operates at optimum capacity with less than four hours of sleep a night? It could be. There are people who are the “sleepless elite” who truly won’t or can’t sleep longer than that, and it has been tied to a specific gene. However, your chances of truly having that gene are about the same as your chances of being hit by lightning.

Wondering if safety naps should be a thing or if they are just an excuse for people to slack off at work? Walker has an answer for that too. (You’ll have to read the book to find out.)

Not into reading? Don’t worry, he also has TEDTalks and MasterClasses on sleep.

Whatever way you prefer to get your information, DO THAT. Listen to his message, and figure out what you can do to prioritize your own sleep.
