Dr. Vass, who serves as the Co-Founder and Chief Medical Officer of Longevity Health, recently shared the five morning rituals he never skips. In an Instagram video, he explained that the first 90 minutes of the day play a crucial role in regulating circadian rhythm, hormone balance, metabolism, and overall health. “As a longevity doctor, these are the five morning habits that I refuse to skip. Not what I recommend casually, but what I actually do every morning. What you do in the first 90 minutes of your day helps to set your circadian rhythm, hormones, and your general metabolic state for the next 16 hours,” he said.
