Outlast aids sleep

17/11/2011
Provider of heat management and moisture reduction technology for textiles Outlast has released details of new studies that show its functional materials work well in bedding applications. The studies used imaging technology in real time to measure the development of temperature and humidity between a sleeping person and a duvet.

According to Outlast, the studies showed that "climate-optimised sleep surroundings" lead to a longer, deeper sleep. "While sleeping humans need to be warmed and to be cooled," the company said on announcing the results. "In an optimal microclimate heat and moisture must play together perfectly."

Body core temperature decreases in the first half of the night by approximately one degree Celsius, mostly through transpiration, which is the body’s own cooling mechanism. By evaporation of moisture, the skin (and also the blood circulation) is cooled down. Using textile technology to help the body cool down helps a person sleep better, the company says.

"Outlast materials can reduce moisture significantly during the phase in which you fall asleep,” said Volker Schuster, technical director of Outlast Europe. “We found in one trial that Outlast materials reduced relative humidity by 10%,
supporting the human body in its attempt to cool down during the phase of falling asleep. A great start to the night leads to an improvement of comfort and better sleep.”
