Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.

Increase Morning Cortisol & Sunlight
And that pulse of cortisol is going to happen once every 24 hours no matter what. It's going to happen and you get to time it. How do you time it? Primarily by when you view bright sunlight or bright light of another kind.
And then once the sun is out, try and get some bright sunlight in your eyes. Never look at any light so bright that it's painful to look at, sunlight or otherwise.
Bright light exposure for 7 hrs. decreased cortisol (the stress hormone) levels by up to 25% the next day.
Oh, yeah, absolutely. Because of course, you know, that’s what entrains to a large degree of cortisol rhythm, and probably cytokine rhythms too.
