My heart rate before bed last night: 38 bpm In the 99.9th percentile. The 40 hour social media fast dropped it by around 10%. Seems social media could be a 10% tax on my nervous system. RHR is the most important marker I track. It's a tell-all of health and habits. This single number reveals stress, food, screens, fitness, relationships and more. Show me your RHR and I'll see your soul. Lowing your RHR before bed is the #1 thing you can do to improve your health. A low RHR will boost sleep quality. High quality sleep: > Mental acuity up 15% > Insulin sensitivity + glucose control better by 25% > Self control up by 20% > Mood enhanced by 15–30% > Physical performance improvement by 10% > Lower injury risk by 20–60% My suggestions for you: + final meal four hours before bed + screens off one hour before bed + read a book 10 min before bed + in bed at the same time every single night Master these and then you can add on more layers to get even better.
