Sleep and recovery tech, reviewed by someone who wears it

FullyOptimized covers the gear people buy to sleep and recover better. It starts with the device we actually wear every night: an Oura Ring, worn for more than a year.

We keep two kinds of pages and label them at the top. Hands-on pages come from our own long-term use. Research-based pages pull together maker specs and published studies, and say plainly that we have not tested the product. Health claims stay inside what the cited evidence supports, and every page lists its sources with dates.

How we work

We do not run a lab and we will not pretend to. Star ratings appear only on products we have used ourselves. Affiliate links are marked, and a product never gets recommended because it pays more. More on the about page.
