#25: Chuck Hazzard – What Most Experts Got Wrong About Sleep And How To Get The Most Out Of A Sleep Tracker

If you care about sleep then you need to hear this episode! I have listened to a ton of podcast about sleep and read about the subject. But I never heard the real story about what we actually know about sleep and why this is essential to understand when hearing advice from sleep studies. If you have ever been stressed by your sleep tracking showing you that you are not getting enough deep sleep or looking into getting a sleep tracker then this is for you. 

Martin & Dasha told me several times that I had to interview Chuck Hazzard about sleep and health optimization. Thank you so much for that. This changed some of my views on sleep as Chuck might be one of the most balanced and knowledgeable people about health that I have meet and at the same time extremely pleasant to talk with.

He is an ultramarathon runner and Vice President of Oura Ring which most of the experts say is the best sleep tracker on the market. 

He shares his own personal journey, what we actually know about sleep, concrete sleep tips, what is important when selecting a sleep tracker and how not to get stressed by a sleep tracker but get true value from it.  

Another important thing Chuck shares is how to navigate this complicated health space.

“Be your own scientist. You’re the best person to judge what works and doesn’t work for you. If it doesn’t cost you a lot of money, it’s worth trying. See if it helps and if it doesn’t, stop doing it before you invest big money. Do your own research. Talk to a lot of people. Don’t just trust the manufacturer.”
