As such, experts recommend turning the thermostat all the way down to 65 to 67 degrees Fahrenheit in the evenings. If you’ve done this and still wake up sweating (and don’t have a diagnosed medical condition), switching out your sheets is the logical next move. Here are the best materials to look for, and nine highly-rated, non-toxic sheet sets that will help you nick the night sweats for good. Price: $548/ Queen Coyuchi’s relaxed sheet set (flat sheet, fitted sheet, and 2 pillowcases) earns high marks for being super soft and less wrinkly than other linens. Made from 100% GOTS certified linen from Europe, each eco-friendly set is shipped off in a reusable, organic cloth bag. Price: $409/ Queen These linen sheets from Avocado live up to the company’s strict environmental standards. Loomed in France, they’re GOTS certified organic and carry the Made Safe seal that designates products free from any chemicals that could harm human or ecosystem health. They also feature a special pre-wash that aims to make them extra comfortable and shrink-resistant. Price: $238/ Queen These sheets from Boll & Branch get their smooth, cooling factor from organic percale cotton woven in ethical, Fair Trade Certified factories. With hundreds of five-star reviews to their name, nightly users report that they’re perfect for the hot summer months. Price: $118/ Queen Beyond being GOTS certified organic, these percale sheets from Under the Canopy earned the Oeko-Tex Made in Green certification, meaning they have been tested for harmful substances and were made in worker-safe, environmentally-friendly facilities. All this to say, you can sleep easy in ’em. Price: $134/ Queen GOTS and Oeko-Tex certified, these Brooklinen cotton sheets are as sustainable as they are snuggly. They’re also one of the most affordable sets on the list, to, as Brooklinen puts it, “give you that hotel-sheet feel without the price tag.” Hop on them quickly to snag the last of their fun, limited edition colorways. (Banana stripe, anyone?) Price: $139/ Queen Mattress company Casper is now getting in on the sheet game, and this set is their coolest to date. Made from 100% Tencel, they’re super breathable for hot sleepers. A standard set comes with a fitted sheet, flat sheet, and 2 pillowcases, but you can bump it up with a duvet cover, too. Price: $199/ Queen Buffy’s cooling Tencel sheets are made exclusively from eucalyptus responsibly harvested in the Czech Republic. The real selling point is their colors: Light blushes and pale blues that get their hues from plant-based natural dyes. Price: $165/ Queen Another company that champions eucalyptus fibers, Sijo churns out cooling sheets that are Oeko-Tex certified. These sheets also come with a 30-night trial period, so you can try them out and return them if you’re not sold.
