“You can test people. When their heart rate variability is good, they're better at everything.”

Greetings, Superfriends. This week, I’m excited to bring you another bona-fide superhuman. Get this – my guest Dr. Kirk Parsley is not only a former Navy Seal and all-around athlete (having seriously competed in football, track and field, power lifting, boxing, multiple martial arts, volleyball, and crew). He’s also a doctor. Through his extensive work with the elite Navy SEALs and extensive personal experimentation, he has become an expert in all things fitness and health, but most specifically, sleep.

Now, you may or may not realize it, but sleep is the foundation for everything we do. Proper, healthy sleep is one of the most basic things that can either hold you back or propel you forward towards your goals – whether they’re fitness related, intellectual, professional, or even emotional goals. It’s for this reason that I’m so excited to welcome this guest. He’s working on a book with the great Robb Wolf all around optimal sleep. He’s designed Sleep Cocktails, a product designed to help people get into restful, restorative sleep more easily. Basically, there are very, very few people on the planet who know less about the correlations between sleep and performance than this guy.

A little bit of fair warning, it does take us 10-15 minutes to really dive deeper and find our flow. Also, make sure you listen through to the end, because we really hit our stride at about 50 minutes and Dr. Parsley starts throwing out incredible take-homes left and right, as well as some fascination biological and physiological facts. You’re sure to learn a lot from this episode, and given some of the mind-blowing facts Doc Parsley describes relating to sleep and performance… it might even change your life.

Favorite Quotes from Dr. Kirk Parsley:

“I was then the least qualified sports medicine guy around – which, in truly military fashion, the obvious solution was to put me in charge of everyone.”
“Drugging yourself to sleep doesn't work. You only drug yourself unconscious.”
“Sleep deprivation and famine or fight or flight all look very similar metabolically. And pre-diabetes metabolic syndrome is probably really tied to refined carbohydrates and sleep deprivation. And if we got rid of those two things, we would probably see Type 2 diabetes become almost non-existent.”
“The ultradian rhythm peaks somewhere between 3:30 to 5:30PM, and that's where 85% of world records are set.”

    Great interview with Dr. Greg Wells! He mentioned a doctor from Colorado around the 42:30 point of the podcast, discussing turmeric and black pepper. I couldn’t make out the doctor’s name. Can you provide me with his full name and maybe his website or contact info. Interested in his products.

    Thanks,

    Rob

    Maybe oarts of the things he has to share are right, maybe not. If I look at him which impact his nurturing and living style has on himself I see a very old looking man! He is year 1973!! That is not old and he looks definitly much older!! If I would not know his birthyear I would guess that he is in his mid-60ies!! A bit concering for someone who claims his lifestyle is suitable for a long life, isn’t it?
