Q&A

Frequently asked questions

Do cooling sheets really work?

They do! With the right design, cooling sheets can greatly improve your sleep.

A regular sheet set can be super comfy, but not all fabrics work for the typical sweaty sleeper. To keep sweat at bay, you need a breathable sheet, which is where cooling sheets come in. With microscopic pores, breathable sheets release body sweat to evaporate into the air during sleep—no more trapped humidity or heat disturbing your rest.

What is the best material for sheets to keep you cool?

For cool sheets all night long, you need a material that’s fully breathable and sweat-resistant.

At Casper, we chose 100% TENCEL™ for our cooling bed sheet sets. A lyocell variant, our TENCEL™ sheet is the perfect combination of cooling technology and luxurious softness.

What are cooling sheets?

Cooling bedding sheets are just like regular bedding but with an added benefit—body temperature regulation.

Through airflow and heat-resistant technology, cooling sheets transfer heat away from your body for a perfectly chilled night of rest. Perfect if you like a cool night’s sleep or happen to be a hot sleeper.

What are the best sheets to keep you cool?

The best cooling sheets regulate body temperature without sacrificing your comfort—a balance of breathability and touch.

To get the best of both worlds, consider these factors for staying cool in between the sheets:

Material – Breathable fabrics (cotton, TENCEL™, bamboo) are better choices for cold sheets than heat-retaining materials like flannel. The more airflow or porosity, the more body heat can escape.

Weave – It’s not just the material—it’s how you use it, too. Certain knits facilitate airflow better than others, like the grid weave pattern in our Hyperlite™ Sheets.

What thread count is coolest?

You might think sheets with a higher thread count are always better. But with sheets for a sweaty sleeper, that’s not the case.

A higher thread count yields tighter weaves which equal less breathability and less cooling. To balance cool comfort and luxurious touch, experts recommend a mid-range thread count, anywhere from 200 to 400. We chose an airflow-friendly 200 thread count for Casper’s Hyperlite sheets.

Learn more in our guide on the best thread count for sheets.

Do cooling sheets work for hot flashes?

They can certainly help. Sweat-wicking, breathable fabrics transfer body heat away, leaving behind a cooler bed. You’ll likely sleep more comfortably, though your hot flashes won’t go away.

How can I stay cool at night?

Our Hyperlite™ Cooling Sheets are just one part of the cooling bed sheet equation. For total body temperature regulation, adopt a few of these nighttime tips:

Cool down your entire bed – Try our breathable mattresses, duvets, cooling pillow, and mattress protectors—all created with our unique cooling technology.

Wash up – Take a warm shower or bath before bedtime. The external heat will actually lower your inner body temperature and blood pressure.

Eat right – Avoid eating right before bed, since digestion can spike body heat. Spicy and very salty meals have similar sweat-inducing effects.

Fan it out – Utilize overhead or standing fans for low-energy cooling all night. In particular, place box fans in windows to push hot air out as cool air blows in.

Learn more in our guide on how to stay at cool at night.

How do I care for my bed sheets?

All of our bed sheet sets are machine washable. We recommend washing your bed sheets in cold water on a gentle cycle. Tumble dry low and remove from the dryer as soon as possible to keep them wrinkle-free. Warm iron as needed.

To keep your white bed sheets looking good as new, use a non-chlorine, oxygen bleach with each wash and wash them every one to two weeks. Learn more about caring for your bed sheets and check out our guide on how to whiten sheets.
