Sleep writer Amelia Jerden runs hot. So, in her hunt to try the latest bed-cooling technology (that goes beyond what a cooling mattress or crisp percale sheets can provide), she tried Eight Sleep Pod 4. In essence, it’s a fancy (and very expensive) heavy-duty fitted sheet with thin tubes running all through its surface that fill with water to cool you down. Oh, and it also uses AI to track and adjust your ideal sleep temperature. At an extra $17 a month, Amelia’s not sold on the AI of it all, but for more on how well it cools, read her testing experience so far.

Also on the site: Beauty writer Rachael Griffiths tried dozens of hair oils and her favorite is suitable for all hair types and only $20, Brenley Goertzen answered our How I Pick My Picks questionnaire and told us about her favorite plain white socks and how she believes black T-shirts are a non-negotiable, and contributor Emily Price asked bartenders about the best rocks glasses to add to your bar cart. —Ashley Wolfgang, newsletter editor
