Cooling sheets can help people with sensitive and easily irritated skin. Rough, itchy, and low-quality materials used in bedding can aggravate skin conditions, such as eczema, according to Dr. Chacon. “It's important to note that cotton is often helpful for people with skin conditions,” she says. “Percale and sateen, which is made from woven cotton and is soft and silky, are best for individuals with eczema.”
