Most cooling sheets feel cold when you climb in and are damp by midnight. These work the other way round. The Xirotex fibers absorb heat before you start to sweat, hold it while your body runs hot, and let it go as you cool down again. The sheet under you stays dry, all night.

Night sweats are a swing, not just heat: soaked at 2 a.m., then cold in a damp bed at 3. Because the fabric takes heat in as you warm up and releases it as you cool, the swing flattens out. Lusome rates the sheets at up to 5 degrees of temperature regulation, and customers describe it more simply: sleeping through.

No slippery synthetics and no gel layer. This is 400 thread count, 100% long staple cotton percale, the crisp hotel kind, and the temperature regulating technology is in the fibers themselves. It is USDA BioPreferred. The two words customers use most are comfortable and soft, and only then do they mention it works.

In a 2025 study published in Frontiers in Sleep, Harvard-affiliated and Brigham researchers had 64 people sleep on these sheets for six weeks. On average the group reported about 26 more minutes of sleep a night, and a third of those who started with night sweats said they had stopped. That is a group average of self-reported sleep, not a promise for any one person, and it is the reason the sheets exist.

These are not cheap sheets, and the reviews that mention the price tend to end the same way. “Though they’re pricier than standard sheets, the cooling benefits make them worth every penny.” Allison, verified customer.
