Repeated tests showed that after seven hours of sleep, TEMPUR beds provided relative humidity levels below 50%, while TEMPUR material temperature rested at 36.1☌.īut it’s not just science that TEMPUR has on its side – TEMPUR owners also have something to say about their experience. TIME FOR THE SCIENCEĪ recent independent test by Ergonomie Institut München measuring heat generated and retained during a seven-hour sleep period, found that TEMPUR beds sleep cooler than the competition. It draws in surrounding cooler air, circling away the warmer air created by your body. On the other hand, with an open-cell structure, a TEMPUR material is made up of billions of open-cells, which allow for easy ventilation through the night. What about foam? Traditional foam and memory foam mattresses utilise a closed-cell structure, which retains body heat, keeping it close to your body. Not only will it no longer feel cool, that gel layer acts as a barrier, preventing ventilation and causing your temperature to rise even further. Unfortunately though, while it may be cool to lie on initially, that gel layer soon reaches body temperature. Some people choose mattresses with a so-called cooling gel layer, thinking this will provide a colder spot to sleep. So, what can you do to sleep cooler? While your mattress certainly doesn’t generate heat, the mattress you choose can make a big difference to your temperature. We can also overheat due to stress or anxiety in our life, or it could simply be our choice in bedding. These can include our age or weight, our diet or overall health, our hydration levels or any medication we are taking. There are many factors that can contribute to overheating in bed. But, while we may think it’s our mattress’s fault, mattresses do not generate heat – we do! When we get overly warm in bed, it can be tempting to blame our mattress. In winter, we often over-compensate for cooler temperatures in the sleepwear and bedding that we choose, making us hotter than we need to be. In summer, heat can cause problems when the ambient temperature increases and the mercury starts to rise. Feeling too hot while sleeping can result in poor sleep through the night, and can sometimes prevent getting to sleep at all. While it may be elusive for some, that comfortable night often means sleeping on a bed that offers just the right amount of support in perfect comfort, surrounded by tranquil darkness.īut, getting the rest you need also means finding the right temperature. A good night’s rest usually comes from a comfortable night’s sleep.
