What protocols are recommended for improving circadian rhythm?

To improve circadian rhythms, Andrew Huberman and the Huberman Lab suggest several practical protocols:

1. Morning Sunlight: Aim to get 2 to 10 minutes of sunlight exposure in the morning when the sun is low in the sky. This anchors your biological clock, enhancing mood, sleep, hormone regulation, and cognitive functions. If sunlight is unavailable, artificial blue lights can be beneficial 1.

2. Regular Light Exposure: Ensure access to bright light within an hour of waking, ideally from sunlight. Repeat this exposure for 10 to 30 minutes in the afternoon or early evening to maintain circadian entrainment. Minimize bright light exposure at night to support sleep 2.

3. Exercise and Movement: Engage in physical activity at consistent times each day, and consider morning exercise to stimulate your circadian clock. Physical activity, combined with adequate light exposure, helps synchronize your internal clock with the day-night cycle 3 4.

4. Consistent Meal Times: Try to eat meals within a similar time window each day, even if the exact times vary. This habit supports circadian rhythm stability and overall health 5.

5. Use of SAD Lamps: If sunlight exposure in the morning is not practical due to location or schedule, consider using a SAD lamp for 5-10 minutes to simulate natural light exposure 6.

These protocols, by aligning your lifestyle with natural light-dark cycles, can significantly improve your circadian rhythm, thereby enhancing overall health and well-being.
