view sunlight before the sun is overhead (even if through cloud cover) & exercise (ideally outside) before 2pm.
To adjust quickly to daylight savings, get up at your usual (clock) time & get 10-45min of exercise, ideally outside & facing the sun (if it’s out/rising/even if cloudy).
this study had people exercise in the early part of the day, certainly before 2:00 PM and ideally before noon.
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
