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.

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.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
In the metric system this would be 2 milliliters per kilogram
A simple formula, what I call the Galpin Equation, which is your body weight in pounds divided by the 30. That is how many ounces you should drink for every 15 minutes of exercise.
The galpin equation is based on the fact that we lose about 1 to five pounds of water per hour which can definitely impact our mental capacity and our physical performance. And the formula for hydration, the so-called galpin equation is your body weight in pounds divided by 30 equals the ounces of fluid you should drink every 15 minutes.
