What is the perfect temperature for a good night's sleep?

Sleep is as essential body function like eating and drinking. It is when several biological processes that are fundamental to our health take place. These processes include the storage of new information, communication, and the reorganization of nerve cells, all of which support healthy brain function. In addition, sleep has a restorative effect on the immune system.

On average, the human body goes through 4 to 6 cycles during the night, varying between the lightest sleep cycle (non-REM sleep) and deep sleep (REM sleep). REM sleep is the most important and most difficult cycle to achieve. It is in this cycle that we dream, where breathing becomes faster and irregular, increasing the heart rate to levels close to those of when we are awake. In this phase, the muscles are also "paralyzed", due to the blocking of motor neurons by the brain, which prevents us from physically reproducing what we are dreaming. Therefore, sleep is fundamental for the maintenance of cognitive functions such as memory, creativity, and learning.

Not sleeping well will trigger problems such as lack of memory and/or concentration, mood swings, immune system failures, weight gain, risk of cardiovascular diseases, and even diabetes. Experts recommend a regular bedtime and wake-up schedule, avoiding excessive consumption of alcohol or caffeine, eating light meals before bed, sleeping on a comfortable mattress and pillow, and sleeping in an environment with a temperature adjusted to one's needs.

But why does temperature have so much influence on our sleep?

During REM sleep our body releases less energy because the motor neurons are paralyzed. This process decreases our ability to regulate body temperature.

According to experts, the ideal temperature for a good night's sleep is between 18 and 22 degrees. However, this ideal temperature varies from person to person not only because of personal taste, but also because due to gender, age, and health problems. For example, women usually need a higher temperature than men to sleep well, because women's muscle mass is generally smaller and therefore have less energy expenditure. The same is true for the elderly and people who suffer from poor circulation.

To ensure a temperature adapted to your needs, look for for open cell foams with heat dissipating additives such as Coolgraph, Coolflow or Cuprum.
