The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

It's going to be very important for you to get that morning bright light ideally from sunlight, get that cortisol peak going. Other ways to increase that cortisol peak would be to do some physical activity.
is something like if you wake up in the morning and you go outside for 30 minutes or an hour first thing in the morning, like...Most people are drinking their coffee. Well, maybe what you need is bright light exposure instead of your coffee, or drink your coffee outside.
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.
