One surefire way to beat the heat when you’re trying to get in some quality Zzzs is to invest in a set of cooling sheets. When shopping for this type of bedding (which is ideal for summer, but great for year-round use as well), it’s important to read the fabric details of what you’re buying. Look for materials like cotton, percale, linen, and bamboo, which are all known to regulate body temperature and hold on to the coolness in the room that your air conditioner works so hard to create. Luckily, the Nordstrom Anniversary Sale is going on right now, and the department store marked down so much cooling bedding, including sheets, blankets, and pillowcases, for its yearly blowout. Brands you know and trust for their quality and durability, like Boll and Branch, Ugg, and Nordstrom’s own in-house label, are seriously discounted right now. Below, we rounded up eight of the best cooling bedding buys from the sale to help you keep your cool as you sleep.
