If you’re looking to improve your sleep, knowing the best places to buy bedding and which sheet colors to avoid are great places to start.

Nylon may be well known for its durability, but the benefits of this silk-like material mean it’s actually not suitable for the bedroom.

“Nylon is a material that shouldn’t be in bedding,” says Stephen Light, Certified Sleep Science Coach and CEO of Mattress Nola (opens in a new tab). “While it is durable and tear resistant, it is also water resistant. This means it is not breathable and can trap your body heat. feel uncomfortable and have trouble sleeping.

And Stephen is not alone in his feelings. Amelia Jerden, sleep accessory specialist at Sleepopolis (opens in a new tab), reinforces that nylon is best left beyond your best mattress. She, too, suggests that the water-resistant qualities of nylon won’t absorb your sweat or body oils, increasing your risk of skin irritations and interrupting your sleep.

Like nylon, polyester is admired for being strong, tear-resistant and hard to wrinkle – these qualities are all part of their downfall. However, the problems with polyester don’t end there.

“Polyester should be avoided because most are made with carcinogens that can lead to heart, lung and skin problems,” Amelia says. “It has also been shown to cause respiratory problems and negatively affect the immune system, especially in children.” Polyester is also a non-biodegradable fabric (like nylon) and contains “toxic chemicals” that are harmful to the skin and the environment.

You’d be forgiven for believing that the material with a thread count of over 1000 is among the finest luxury bedding on the market. However, this is not always the case. Tony Klespis, Certified Sleep Science Coach at Clarity of the mattress (opens in a new tab)urges caution when investing in sheets with a particularly high thread count – warning that they are not always what they seem.

“A common misconception when looking at sheets is that the higher the thread count, the better the quality of the material,” he says. “Be skeptical of sheets with a thread count over 1000 because sometimes companies inflate the thread count on their label by using threads with multiple fibers in each. This can result in a less durable material that can pill more easily.

4. Weighted Blankets

Weighted blankets may be fine if you have no trouble sleeping in the heat. However, if you’re looking for how to keep a bedroom cool, experts advise looking for a cooler alternative. “Weighted blankets have a heavy design to help you relax, but they also tend to trap heat,” warns Tony.

If you’re looking for the comfortable style of a weighted blanket, it’s best to look for a weighted blanket designed to keep you comfortable, such as ones with a loose knit design to promote cooler airflow.

5. Flannel Sheets

Likewise, if you are a hot sleeper, it may be best to avoid flannel sheets whenever possible. Tony explains that, like weighted blankets, flannel can make you overheat and disrupt your sleep in the process. “Bedding with a high thread count traps heat because there is no space between the threads for air to circulate,” he adds.
