World-famous sleep brand Casper mattress has just released a new comforter, called the Down-Alt Duvet, designed to help regulate your body temperature. Feeling too hot in bed is a pesky sleep issue for many of us, and one which Casper, one of the world’s best mattress online brands, is looking to ease with its new comforter. 

The Casper Down-Alt Duvet made from Tencel, a naturally cooling and breathable material created to help you sleep comfortably…  and not wake up a hot, sweaty mess. Naturally this is excellent news for hot sleepers, as Casper has designed the duvet to stay cool to the touch throughout the night. 

As it’s brand-new, the comforter isn’t yet part of the best Casper mattress deals and bedding offers, and retails for $179 for the Twin/Twin XL size, $199 for the Full/Queen, and $229 for the King/Cal King. And if it goes on sale among the best Amazon Prime Day mattress and bedding deals, we'll let you know.

Inside the Casper Down-Alt Duvet lies swathes of fiber made from sustainably sourced wood pulp, plus recycled polyester made from water bottles. Altogether this makes the duvet feel light and airy, yet squishy-soft for more comforting sleep. Caring for it is simple too - just pop it in your washer dryer (cold wash, then tumble dry on low).

The Casper Down-Alt Duvet measures as follows:

  • Twin/Twin XL - 74 x 98 inches
  • Full/Queen - 95 x 96 inches
  • King/Cal King - 111 x 98 inches

The new Down-Alt Duvet joins two other Casper comforters: the Down Duvet (from $250), made with ethically sourced down, and the Humidity Fighting Duvet (from $350), infused with moisture-wicking wool. Both of the existing Casper duvets are far pricier than the newcomer, so if you’ve always wanted Casper bedding, including its best pillows for sleep, but have a smaller budget, the Down-Alt Duvet is the one to pick. 

How do temperature regulating duvets work?

If you’ve been looking at our guide to the best cooling mattress and wondering what else you can do to stay cool yet cozy while asleep, the new Casper duvet is worth considering. That’s because it helps regulate your body temperature for better sleep. That also means it can help you to feel warmer during colder weather. 

So, how do these types duvets work? In a nutshell, comforters using fabrics and other innovations to control your temperature are designed to transport excess warmth away from your body - far more than traditional bedding is able to. This should help you to not overheat in bed, or wake up hot and flustered, kicking off the comforter while desperately trying to find a cool patch.

Temperature regulating duvets are ideal for anyone who naturally sleeps hot, as well as for people who experience night sweats, or hot flashes (flushes) due to peri-menopause or menopause. Many women also experience a slight rise in body temperature just before their period, so a temperature regulating duvet could make a difference in how well they sleep pre-period too. 

Some of the best bed toppers are also cooling, so a good idea for hot sleepers not yet ready to buy a new mattress. Although if you do want a new mattress, we'd also recommend taking a look at our guide to the best Purple mattress deals for another affordable bed company, or the best Saatva mattress discounts for luxury sleep for less.

How to stay cool at night

There are multiple things that can affect how cool or hot you sleep at night, starting with what you’re eating and drinking before bedtime. When we spoke to James Wilson, a Sleep Behavior and Environment Expert, about how to sleep better, one of his main pieces of advice was to avoid eating a heavy meal in the three hours before sleep. That’s because digesting a heavy meal causes a rise in our core temperature.

Avoid exercising too close to bedtime, as that will also raise your body temperature, and experiment with taking a cold shower using cooling mint shower gel close to bedtime. It could be your secret weapon for a more comfortable night’s sleep.

Keeping your bedroom at the best temperature for sleep, which is a cool 65 degrees Fahrenheit, according to experts, will also lead to better, more comfortable sleep. In summer, central air conditioners or a great tower fan are your friends.

Also, close your bedroom blinds or curtains during the hottest parts of the day to prevent heat from building up in your sleep space. Once the temperature drops, and if you don’t have AC, open the windows to boost airflow.

Staying hydrated throughout the day is beneficial for your wellness on every level, including your sleep. Drinking tea, coffee or alcohol before bed, on the other hand, can actually disturb your sleep.

During the colder months, when you’ll have your heating on more, use one of the best smart thermostats to create a nighttime schedule that ensures your heating is automatically set up to help you sleep more comfortably.
