Not only your mattress may help you sleep cool. Consider your sleep surroundings. Mattresses and sleep accouterments may aid or impede temperature neutrality. Determining your perfect sleep temperature might help you sleep better. Choosing why do mattresses have fiberglass cool bedding Temperature might affect sleep quality. A National Sleep Foundation study indicated that cool room temperature was significant to four out of five respondents. 65 degrees Fahrenheit is the ideal bedroom temperature 18.3 degrees Celsius. Most experts suggest 60 to 67 degrees Fahrenheit 15.6 to 19.4 degrees Celsius for the most restful sleep.

What’s The Optimal Sleep Temperature?

There’s no perfect sleep temperature for everyone. Most folks sleep best at 65 degrees Fahrenheit, experts say. Many individuals are unusual. Some like a warmer environment, while hot sleepers require a colder one. Try several temps to find what’s most comfortable.


The sheet set you pick might affect your nighttime warmth. Flannel, fleece, and heavyweight cotton sheets insulate and retain heat. Hot sleepers shouldn’t use these sheets. Lightweight cotton, linen, and Tencel lyocell sheets are cooler. Breathable cotton sheets are lightweight. Percale and sateen are common weaves. Percale is crisper than sateen, yet both are breathable. Linen is cool, yet it might feel scratchy. Manufacturers pre-soften linen sheets or make linen-cotton blends. Tencel lyocell is a moisture-wicking wood pulp fibre. Most “bamboo” sheets are bamboo-derived lyocell. Some cooling blankets incorporate Coolmax or Outlast fibres. Coolmax is a moisture-wicking polyester. Temperature-regulating Outlast fibres may be woven into fabric.


Today, many pillows are cooling. If a down or polyester pillow is too warm, try a memory foam or latex cushion. Manufacturers aerate memory foam and latex pillows to promote airflow or add gel or other cooling ingredients. Sleepers may also buy cooling pillows with air or water chambers. Higher-priced yet effective.


Some blankets warm, others chilly. Hot sleepers should avoid wool, down, fleece, cashmere, and thick cotton blankets. Thinner, lighter blankets are cooler. Lightweight cotton, cotton blends, Tencel lyocell, and linen make cool blankets. These airy textiles won’t trap body heat. Some blankets feature Coolmax or 37.5 technology to cool. Coolmax is moisture-wicking and breathable, while 37.5 fabric is engineered to maintain an optimal body temperature.


A mattress topper might assist if you don’t want to replace your mattress. Mattress toppers affect a mattress’ feel. Toppers vary in thickness and material. Memory foam mattress toppers are the warmest. Hot sleepers shouldn’t use them unless they’re aerated and laced with gel, charcoal, or another cooling substance. Down toppers also retain heat. Cooling mattress toppers include wool and phase change material.

Bedroom Cooling Tips

Follow these tips to adjust your bedroom temperature for sleeping:

  • Close curtains to decrease daytime heat.
  • Summertime: Downstairs
  • Nighttime temperature reduction
  • In warmer climes, use a fan or air conditioning or a hot water bottle.
  • Ventilate by opening windows
  • bedroom humidity
  • Temperature-regulating mattress, sheets, duvet, comforter, pillow, and pyjamas reduce perspiration.
  • Hot bath
  • before bedtime to chill down naturally.

Be nice to your internal thermostat to help your body prepare for sleep. As the circadian rhythm is susceptible to light, nutrition, and exercise, timing may affect body temperature and tiredness.
