Frequently Asked Questions
Here’s everything you need to know about our sheets.
Our Xirotex™ Cool technology proactively absorbs heat before your body starts to sweat, regulating temperature by up to 5°C. The result is a dry, comfortable night’s sleep without waking up drenched.
Yes, in an Ivy-League Medical School study, 69% of participants reported better sleep, 42% had fewer night-sweats, 33% were completely night-sweat free and sleep duration was increased by 26 min per night. Our technology is engineered specifically to support women through menopause and perimenopause.
Not at all. While they’re a game-changer for menopause night sweats, anyone who struggles with overheating, restless sleep, or humid nights will benefit from our sheets. They are great for bed sharers who sleep hot too!
Most “cooling” fabrics rely on wicking — moving sweat once it’s already there. Lusomé Sheets with Xirotex™ Cool go further: they absorb heat before sweating starts, keeping your body at its ideal sleep temperature.
Machine wash cold, tumble dry low. Do not use fabric softener — it can block the performance technology.
Yes, our sheets dynamically respond to body heat, absorbing and releasing energy as your temperature changes. That means they keep you cool in summer and cozy in winter.
