There is no need to wake up in cold sweats or with chills at night. This deep dive into the best sheets for hot and cold sleepers can improve your rest.

A comfortable bed is only part of the formula for a great night's rest. The mattress is paramount, as is the overall sleep climate. Once you get that right, your sheets help elevate the sleep quality experience because you feel them directly against your body.

This is why sleeping in the best sheets year round — whether you are a hot or cold sleeper — is such a game changer.

You may have cold sweats at night and find that certain types of sheets hold your heat, helping you log those sleep hours. Or you may get chilled at night, maybe by air conditioning in the summer. Then you might prefer a sheet to keep you warm — but not too warm.

Thankfully, Sleep Number offers a wide range of sheets for hot or cold sleepers — read on to find the best fit for you:

Summer Sheets for Those Who Sleep Hot at Night

The key is to find the right type of sheet for your optimal comfort, and that's where understanding thread count, fabric type and body temperature come into play.

“I NEVER thought sheets would make such a difference," says KDS5, a recent user who tried the True Temp™ sheets by Sleep Number. These sheets utilize patented technology to keep the human body at 37.5 Celsius, which is the body's most comfortable temperature setting. “The cooling effect is very noticeable. Very well made and not too 'thin.'"

Great for summer, the 37.5® performance technology is created with the understanding of the relationship between heat, humidity and keeping you cool while you sleep.

Additionally, recent studies show that fabric and fabric weave make a significant difference when it comes to mitigating sleeping hot at night while also influencing the overall amount of time spent in restorative rest phases of sleep.

A 2020 study in the Textile and Leather Review found that the majority of those studied indicated the quality of the bed linen fabric directly impacted their quality of sleep.

“The fiber factor received the highest weightage because the thermal and moisture properties, breathability, etc., of the fabric are mainly dependent on fiber properties, and sweat release, body temperature and trapped body heat have an important role in good quality sleep," the study authors write.

Soft Cotton Sheets for Restful Nights

Those insights show why Sleep Number True Temp™, Supima cotton and Essential Fit sheets are such popular options for consumers looking to upgrade their sleep experience.

Supima cotton is the most environmentally friendly and sustainably produced sheet set from Sleep Number® with a thread count of 600. That high thread count means it is oh-so-soft and only gets softer with subsequent washings.

“Supima are my personal favorite," says Sleep Number bedding expert, Lori.

They are also Oeko-Tex certified and feature corner elastics on the fitted sheets to prevent accidental removal or bunching.

“The softest sheets I've ever slept in!!," says Sean. “I didn't even know sheets this soft existed until now. I highly recommend these sheets for anyone looking to get the best night's sleep that they've ever had. It's a truly wonderful product and I'm looking forward to the next set I buy."

Silky Sheets for Hot Sleepers

Another option for great summer sheets include the Lyocell Ultra, a silky, bamboo-eucalyptus fabric that is eco-friendly, breathable and naturally moisture-wicking.

“We just bought our first set of Lyocell Ultra sheets and we love them! They are light weight, stay cool, wrinkle free and feel so good against your skin. We will definitely be purchasing a second set," says online customer reviewer, Klm11.

The National Institutes of Health has weighed in on this subject, noting that the optimal sleep temperature region between the mattress and the sheet is a main indicator of the onset of sleep and the amount of time a person stays there.

In 2016, the NIH predicted that the next challenge will be for companies to utilize fabrics to enhance the “microclimate" of the bed in order to optimize shut eye. For 2021, consumers note that shopping sheets that balance out body-heat concerns is the next area of bedroom enhancement.

The Lyocell Ultra can definitely help with that: “These feel amazing on my skin, I love the silky touch. The perfect treat at the end of the day!" says Sleep Number bedding expert, Lauren.

Cozy Sheets for Those Who Sleep Cold

Seasonal sheets are a thing — after all, who wouldn't want to sleep cooler in the summer and warmer in the winter months?

In the winter, sheets that keep body temperatures warm — but not hot — help you go to sleep faster, and stay there for longer.

Consumers tend to switch out their summer sheets (like the True Temp™ sheets) for winter sheets like the Sleep Number® Winter Soft™ between January and March.

The Winter Soft™ sheets are warm, cozy and perfect for the coldest months of the year.

“They are the nicest feeling sheet ever," says one customer. “They are warm when you need them to keep you warm. It was the best purchase we ever made."
