One of the most practical and impactful anti-aging habits: prioritising quality sleep. During sleep the body performs its repair function by removing cellular waste, while balancing hormones and rejuvenating skin and mind. According to Bryan Johnson, sleep schedule is of great importance, because he follows a strict bedtime and wake time routine, and turns off all blue light sources before bed while sleeping in a dark room at a low temperature.

Practical sleep habits:

Stick to a bedtime and wake-up time, even on weekends.
Keep your room dark, quiet, and cool.
Limit screens and bright lights for at least 30 minutes before sleep.
Avoid caffeine late in the day.
Consider gentle wind-down routines, like reading or meditation.
A regular sleep routine is free, accessible, and backed by science for improving health, mood, and longevity.
