Share on PinterestSleeping in hot environments can have negative effects on a person’s sleep quality. For example, having a high body temperature while sleeping can contribute to insomnia, which may negatively impact a person’s day-to-day life. This article explains which types of comforters may help people stay cool during the night. A quick look at the 9 best comforters for hot sleepersBest for night sweats and menopause: Slumber Cloud Tencel Cumulus ComforterBest for children Casper Humidity Fighting DuvetBest for sustainable manufacturing Buffy Breeze ComforterBest breathable Comfort Classics Coolmax ComforterBest for fibromyalgia and arthritis Frankenmuth Woolen Mill Wool Filled ComforterBest for couples Sheets & Giggles Eucalyptus ComforterBest weighted comforter Baloo Weighted ComforterBest antimicrobial Comma Home Eucalyptus Lyocell ComforterBest organic Avocado Green Alpaca Duvet Insert Why choose a comforter A comforter is different from a duvet. A duvet is a plain insert filled with down or synthetic fibers and used inside a duvet cover. This means that people can change the duvet and duvet covers when they want to, such as according to the season. There are varying duvet thicknesses to suit the changing temperatures throughout the year. A comforter, on the other hand, is made out of more durable fabric than a duvet, as it is not used inside a cover. Comforters contain down or synthetic fibers. They offer an advantage over duvets in that they do not move around inside a duvet cover since a cover is not necessary. However, comforters can be harder to wash and will likely become less soft over time. What to look for Here are some features to look for when choosing a comforter for hot sleepers. Outlast technology Outlast is a brand of phase change material (PCM) that experts originally developed for NASA. It absorbs, stores, and releases heat to regulate temperature. It is common in fabrics that continually regulate a person’s temperature. Outlast technology does not wick moisture away from the skin as a person sweats. Instead, it works to prevent sweating by controlling a person’s temperature before they become too hot and begin to sweat. For night sweats, specialist sheets may help. Learn more about them here. Sustainable fabrics Choosing a comforter made from sustainable fabrics or made through responsible production methods means that it will have little negative impact on the environment. Tencel fabric is one sustainable fabric option that manufacturers often use in comforters. Eco-friendly certifications A range of certifications indicates that a company sustainably makes products with safe materials. These certifications include OEKO-TEX, which ensures that companies make products without harmful substances or unethical work practices or conditions and that the manufacturers have produced them in an environmentally sustainable way.

Causes of and remedies for sleeping hot A person’s body temperature responds to the circadian rhythms that control sleep, and body temperature tends to drop before a person sleeps. If a person warms up before they sleep, such by taking a hot bath or shower, the body’s rapid cooling afterward can help induce sleep. A person may also feel hot at night because of the room’s temperature or due to the materials in their mattress or bedding. Feeling too hot during the night is different from experiencing night sweats, a potential symptom of an underlying condition. A person experiencing night sweats should contact a doctor to find out the cause and start the appropriate treatment. When to see a doctor The British National Health Service (NHS) recommends seeing a doctor if a person has regular night sweats that interfere with their sleep. Night sweats can occur during menopause or when people have anxiety, hyperhidrosis, or take antidepressants. Learn more about hot flashes during menopause. A person should contact a doctor for advice if they are experiencing night sweats to get information on the best treatments for them.
