The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
In humans, the pineal sits deep, deep, deep to the surface, and light cannot get in there. In fact, if light can get into your brain, unless you are part of a specific experiment where that's the intention or you're having neurosurgery or something of that sort, then you've got serious issues happening. That pineal sits deep, deep, deep near what's called the fourth ventricle, and it absolutely should not see light directly.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

light cannot despite what some people think out there I'm not going to name names but light cannot get through the skull to the pineal nor is putting a a light in your ear ears going to get there or even in the roof of your mouth very unlikely
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.
