About 40 Winks

We started 40 Winks because we were frustrated. Frustrated by sleepless nights, by conflicting advice, and by products that promised the moon but delivered nothing.

So we did what any rational person would do — we dove into the research. We read the clinical studies, tested the products, and talked to the experts. Then we started writing about what we found.

What We Cover

Our content spans everything in the sleep wellness space — from grounding sheets and PEMF therapy to sleep supplements and mattress reviews. We focus on evidence-based information and honest product assessments. If something doesn't work, we'll tell you.

Who Writes Our Guides

Many of our sleep and wellness guides are written by Mark Hansen. Every article carries a byline so you can see who is responsible for the work and find their other articles.

Our Editorial Standards

We separate educational guides from product recommendations, link to primary or authoritative sources for health claims, and show the publication date on every article. When an article needs a material correction, we update the content and its modified date.

Our content is general information, not medical advice and not a substitute for diagnosis or treatment from a qualified professional. We do not claim that an article has been medically reviewed unless a named reviewer has actually completed that review.

Affiliate Disclosure

Some links on this site are affiliate links, which means we may earn a small commission if you make a purchase through them. This never affects our editorial independence — we recommend products based on merit, not commission rates.
