Morning Sunlight Viewing for Optimal Wakefulness and Sleep

Importance of Morning Sunlight

• Objective: Optimize alertness, focus, and sleep quality.
• Method: Get outside shortly after waking up for sunlight exposure.

Techniques for Sunlight Exposure

Identifying the Right Time

• Bright, clear day
• Sun low or starting to get overhead (low solar angle)
• Cloud cover: still beneficial to get outside

How to View Sunlight

• Look toward the sun, not directly at it (especially if it's painful).
• Blinking is encouraged.
• Avoid painful brightness to protect eyes.

Eyewear Considerations

• Avoid sunglasses in the morning.
• Eyeglasses or contact lenses are fine, even with UV protection.

Key Points About Sunlight Exposure

1. Scientific Backing: Numerous peer-reviewed papers support the benefits.
   • Early light viewing boosts wakefulness and improves sleep.
2. Artificial Light Use
   • Use artificial lights if you wake up before sunrise.
   • Still get outside once the sun rises: artificial lights pre-sunrise don't fully activate wake-up mechanisms.
3. Impact of Artificial Light
   • Early morning: Needs much light to trigger mechanisms.
   • Nighttime: Small amounts of artificial light can disrupt circadian clocks.

Guidelines for Sunlight Exposure Duration

• Clear days: ~5 minutes (3-7 minutes range).
• Cloudy days: ~10 minutes.
• Overcast/rainy days: 20-30 minutes.

Additional Tips

• Avoid getting sunlight through windshields or windows; direct exposure is necessary.
• As a last resort, if you can't get outside, get near a window.
