In a protocol
View bright sunlight outdoors within 30-60 minutes of waking to trigger cortisol peak and set circadian timing.

View bright sunlight, ideally outdoors, within the first 30-60 minutes after waking to trigger cortisol peak and set circadian timing.
“view bright sunlight within the first 30 to 60 minutes after waking

In a protocol
Get at least 15 minutes of morning sunlight within 30-60 minutes of waking to reset circadian rhythm.
“at least 15 minutes of morning sunlight, even if there's clouds out, within half an hour to an hour of waking up

In a protocol
Get outside into real outdoor light as early as practical after waking to anchor the circadian clock; duration is less important than simply receiving the signal.
“Simply get outside, get real light, get it early.

TG▶ 46:30DosageFirst thing in morning, doesn't need to be sunny dayCertaintyexplicitstrong endorsement -
In a protocol
Expose your eyes to natural outdoor light shortly after waking to set circadian rhythm and improve nighttime sleep.
