Health & Wellness

Sleep, food, exercise and supplements, and the claims about them that get repeated until they sound like facts. Each one gets followed back to the study it came from, to see what was actually measured.

Most of what goes wrong in health news is a gap between the study and the sentence written about it: a relative risk reported as if it were absolute, a mouse result reported as if it were people, a definition quietly swapped.

Sleep advice spreads faster than the studies behind it. Worth checking which tricks have anything underneath. Want this one sooner? Tell me.
