What are your recommendations when it comes to wearing sunglasses?

Andrew Huberman provides several recommendations regarding the use of sunglasses and exposure to sunlight:

1. Sunlight Exposure: It's essential to get sunlight into your eyes early in the day and towards the end of the day to help regulate your circadian rhythms and hormone levels. Light exposure at these times is crucial for mood regulation and overall well-being 1.

2. Avoid Overuse of Sunglasses: While sunglasses can be helpful, they should not be overly relied upon, especially in the morning and late afternoon. This is because sunlight exposure during these hours is beneficial for aligning your biological clock 2.

3. Daytime Light: During the middle of the day, when the sun is at its highest and most intense, wearing sunglasses is safe and recommended to protect your eyes from excessive UV exposure, which can lead to eye issues like cataracts and macular degeneration 3.

4. Corrective Lenses: It's fine to wear prescription glasses or contacts as they help focus the necessary light onto your retina. However, avoid blue light blockers during the daytime as they might block beneficial wavelengths that your system needs for optimal function 4.

By following these guidelines, you contribute to maintaining your mood, mental health, and hormonal balance while protecting your eyes from potential harm.
