Ep83: How to Boost Your Cognitive Performance with Sleep (according to a Navy Seal) | with Dr. Kirk Parsley

Without question sleep is the most important physiological process we require as creative professionals (and humans) to function at an optimal level…yet it’s what our work culture prioritizes the least. Proper sleep slows the aging process, keeps us lean, restores our immune system, and it protects our memory. Much to the chagrin of ‘Type A’ over achievers, quality sleep is every bit as important as oxygen, food, and water.

So then why do we proudly wear our “Sleep Deprivation Badges of Honor” on our sleeves and work ourselves to death even though every bit of research that points to chronic sleep deprivation destroying our ability to cognitively function at a level higher than being chronically drunk at work.

Today’s guest is no stranger to the detriments of sleep deprivation. Dr. Kirk Parsley is a physician for the Navy Seals and a former Navy Seal himself. And there are quite possibly no two professions on the planet better known for chronic sleep deprivation than being a Seal or being a doctor. Having experienced firsthand the negative effects of chronic sleep deprivation, Kirk has now become and advocate for the health benefits of sleep and is now a world-renowned sleep expert who travels the world evangelizing sleep, wellness, and hormone optimization.

Before you considering sacrificing “just a couple hours” of sleep today or this week to get just a little more work done (or to watch just “one more episode”), I encourage you to listen to this interview to better understand not only what sleep deprivation is doing to your creative brain but also more importantly what you can do about it.
