For today’s podcast, I’ve rounded up several of the NBT coaches to look more deeply at the single factor that is capable of improving athletic performance, mood, testosterone levels, blood glucose, fatigue, productivity, stress tolerance and gut health. We’re talking about sleep - the under-rated and often slighted backbone of a healthy lifestyle. In today’s busy world it’s easy to put sleep last on the list, but there are many reasons not to let that happen.
Coaches Megan Roberts, Clay Higgins, and Zach Moore are with me today to discuss the specific benefits of getting good sleep, as well as evidence-based steps you can take if you’re struggling with persistent thoughts at night or waking too early. We share what has worked for our clients (and ourselves!) to create habits and environments conducive to sound sleep.
