Why is my mattress hot? 6 Important Tips to prevent overheating while sleeping
I get this question a lot. “Bowie, are your mattresses hot?”
The most common question hot sleepers ask. “Is the mattress hot?”
Here is the truth. “No mattress is hot because mattresses don’t generate heat but they do hold onto your body heat.”
The heat-retaining department within the mattress is the foam and every single mattress will more or less have foam within it.
Does that mean they are all too hot to sleep on?
This article will give you 6 tips to prevent buying a mattress that’s too hot for you.
Why do foam hold body heat?
Foam is made up of billions of open-cell, with rubber-like walls.
The denser the foam is the less breathable it becomes.
That is why we heard about Latex and Memory Foam beds being too warm sleep on (they are generally much denser than normal polystyrene foam)
These premium bedding material are widely used within the mattresses.
You shouldn’t let this stop you from buying a mattress with Latex or Memory Foam as these are the best foam for durability and comfort.
Our body is constantly generating 37 degrees of heat. That’s pretty warm.
To avoid our body heat being trapped in the mattress, here are 6 tips on what you can do.
#1 – Wear light and breathable sleepwear
It is the perfect opportunity to let your body breath in your own cozy private space.
Wear something light and breathable helps to keep you cool at night. (some prefer not wearing any at all. well, no harms done in your private bedroom. Why not?)
# 2 – Don’t use a thick foam only mattress
Like we mentioned above, the heat retaining department is the foam within the mattress.
If you are a hot sleeper and often sweat while getting to sleep, there is a good chance you will overheat on the foam only mattress.
If you produce a lot of sweat and oil into the foam, it will substantially decrease the durability of the foam. (It will lose its support much sooner)
On the other hand, Innerspring mattresses will be a better option if you tend to overheat at night.
Innerspring mattresses are open structure in the support layer and tend to disperse heat quicker throughout the night.
# 3 – Don’t use a plastic mattress protector
When it comes to air circulation, polyester is one of the least breathable material you can go with.
Most polyester mattress protectors claim they are durable and boast resistance to chemicals, waterproof, mildew, abrasion, stretch, and mildew.
While some claims might be true about water-proof, polyester mattress protectors are not performing too well in terms of letting the heat go!
#4 – Keeping your bedroom nice and cool
Nowadays bedrooms aren’t always well-insulated.
Some are built on the outer perimeters of the house where the bedroom is directly under the sunlight for hours.
Some are even built without windows!
Your bedroom could be keeping a lot of moist and heat throughout the day.
Make sure you open the door and windows half an hour before you go to bed.
Turn on the air-conditioner or fan to insulate the bedroom a bit.
Try not to put your bed right at the external wall of the house. (that usually is the hottest wall of the house and the coldest too!)
#5 Throw away the extra warmth doona and blankets
Just like mattress protectors, the other heat-retaining department is your bedding.
If you sleep hot, your best bet is not to let your body heat built up in the first place.
Using light breathable bedding like cotton and natural fibre like wool help disperse heat.
Good quality cotton sheets with 300-700 thread counts tend to work better for dispersing heat.
#6 – Sleep on a firmer mattress
If all of the above doesn’t work, your best option is to sleep on a firmer mattress.
A mattress with less comfort layer will retain less heat throughout the night.
Your body won’t sink in the mattress as much.
You will remain on top of the mattress throughout the night.
That will improve air circulation.
