About us

How we write about health

Health Bright Labs publishes free health guides based on published research. We don't diagnose or treat anyone, and nothing on this site replaces advice from your own clinician.

Plain language first
We write for everyday readers. When a medical term can't be avoided, we explain it.
Sources you can check
Every guide links to the studies and public health agencies it draws on.
Kept up to date
We revisit guides when new research comes out. Each article shows the date it was last reviewed.
No miracle claims
When the evidence is weak or mixed, we say so at the start of the article.

How often will you email me?

About once a week. Every email has a one-click unsubscribe link at the bottom.
