Can a mattress topper help keep you cool?

If you sleep hot then you’ll know how uncomfortable it is to wake up feeling all sweaty. And it’s not just about feeling uncomfortable, overheating at night can lead to decreased sleep quality so you will either wake up at night or start every morning feeling exhausted. Whilst there are plenty of things you can do to try to cool your room down before you go to sleep, the key to a cool night’s sleep often lies within your mattress. 

There are plenty of cooling mattresses available but if you don’t have the cash to splash out on a new one then a cooling mattress topper is a great choice. Cooling mattress toppers like the Serenity by Tempur-Pedic use Phase Changing Materials (PCMs) which absorb excess heat and then releases the heat back into the room when the temperature starts to dip, so you remain at a nice, ambient temperature all night long. 

Some of the best mattress toppers also have a layer of gel-infused memory foam which are designed to dissipate heat and create a cooler sleeping service. There’s also the materials that the covers are made from, when it comes to a cooling mattress topper these are almost always breathable fabric with moisture-wicking properties. 

Mattress toppers can definitely help you sleep cooler at night and they also add an extra layer of comfort and support which is handy if your bed is old or starting to feel uncomfortable.
