The fun part

The headline. The study.

Most "health news" is a game of telephone between a study, a press release, and a tweet. Click a card to flip it — front is what you saw, back is what the paper actually said.

A note from Jay

I'm Jay. I'm not a doctor, I'm not a guru, and I'm not selling you anything. I just spend a stupid amount of time reading studies, untangling protocols, and translating the complicated stuff into language a normal person can actually use.

Health Asylum is where I publish the long form essays I wish existed when I started untangling my own health. No newsletters with fourteen affiliate links. No threads pretending a five minute habit will change your life. Just careful reading, plain language, and the occasional jab at the wellness industrial complex.
