Morning Sun — No Sunglasses, 10 Min
Skip sunglasses for the first 10 minutes of outdoor light each morning — eye-level light exposure, not the clock, is what anchors the circadian rhythm.
Skip sunglasses for the first 10 minutes of outdoor light each morning — eye exposure to natural light, not the clock, is what anchors the circadian rhythm. Windows and sunglasses both filter out the wavelengths that set it, so the exposure has to happen outdoors and bare-eyed.

Transcript & sources → All videosMr. Age is AgeGen's editorial character. Facts come from the protocol above.
The protocol
- Timing: first outdoor light of the day.
- Duration: 10 minutes.
- Frequency: daily.
- Rule: no sunglasses; regular prescription glasses are fine; never stare directly at the sun.
What you get
- Circadian anchoring — the clock resets to local solar time.
- A stronger cortisol awakening response.
- Properly timed evening melatonin onset later in the day.
Contraindications
- Photosensitising medications.
- Recent eye surgery.
- Severe migraine triggered by light.
Evidence level
High. Outdoor morning light is one of the best-supported circadian anchors in sleep science — eye-level light exposure, not the calendar, is the main signal the brain uses to set the day's hormonal rhythm. Sunglasses and window glass both filter the wavelengths that drive this signal, which is why the rule is "outdoors, bare-eyed" rather than just "go outside."
