Mattress Too Hot: Six Ways to Cool it Down

Mattress Too Hot: Six Ways to Cool it Down

You wake up in the middle of the night feeling hot and sweaty.

If this happens regularly, you have to ask yourself if your mattress is the culprit. It might be!

What causes a mattress to get too hot?

A mattress can become uncomfortably hot to sleep on if it doesn’t have enough air circulation. In addition, if your mattress causes you to sink into it because of how it’s made this can also lead to feelings of heat that can disrupt your sleep.

Luckily, there are ways to cool down your mattress. Here’s what you need to know about mattress sweats, along with tips on how to prevent the problem from occurring in the future.

So, Why Does Your Mattress Make You Sweat?

One of the hottest mattress materials is memory foam.

As great as these mattresses are for your posture and muscles, memory foam mattresses are unfortunately common culprits of night sweats.

That’s because they contain synthetic fabrics which cause them to be unable to regulate temperature.

In addition, they don’t absorb moisture, so if you sweat during a hot night it will remain on your bed and continue to make you feel hot instead of cool you down.

If you’re set on purchasing a memory foam mattress, consider a product that contains natural, more breathable fabrics.

A traditional memory foam mattress, otherwise known as viscoelastic, is notorious for creating heat.

On the other hand, latex is the coolest material and worth purchasing if you battle with the heat at night.

However, sometimes it’s not just your mattress that’s making you feel too hot. It could be other things.

In order to prevent overheating at night, here are five tips to cool down your bed.

Encourage The Right Temperature In Your Bedroom

If your bedroom is hot at night, this can make the issue of a hot mattress even worse.

Ideally, the right temperature for sleep is between 60 and 67 degrees Fahrenheit.

The reason for this is because your body temperature naturally goes down before bedtime so that you can fall asleep.

Therefore, keeping the air around you within that temperature range encourages the body’s natural sleep process.

Once you’ve got the temperature in your room right, you can tackle the issue of your hot mattress with other simple tips.

Get A Topper For Your Bed

Hybrid beds usually have a memory foam surface and this is comfortable as well as supportive for your body, but the downside is that memory foam can make you feel hot, especially if it’s a thick layer.

Foam has a hugging effect around your body as it moves to accommodate your position during sleep.

To deal with this issue, you should get a bed topper. A bed topper is basically a layer or pad that you put on your mattress.

Choosing one in a breathable material, such as latex, can help to keep you cool at night – and it’s a non-expensive bed makeover! 

Whether you own a hybrid, memory foam, or innerspring mattress, a topper can help to prevent night sweats.

Wear The Right Clothing To Stay Cool

The clothes you choose to sleep in can greatly affect your temperature during the night.

Avoid materials that aren’t breathable, such as polyester which doesn’t absorb water and can make you feel sweaty.

Another fabric to avoid is fleece. Although it might seem like a good choice during the winter months, it prevents air from circulating, which can make you sweat, as reports.

Choose fabrics that will keep you cool, such as cotton. It’s breathable and doesn’t irritate your skin.

During the colder months, flannel is a better choice than fleece or wool. While it keeps you warm, it also promotes air circulation so you won’t overheat or feel uncomfortable during the night.

Choose Breathable Bedding

As with the clothing you sleep in, you want your bedding to promote air circulation and prevent the accumulation of moisture that can make you feel hot.

Some great bedding choices include 100 percent cotton or bamboo. These are both breathable and moisture-wicking. In addition, they’re natural fabrics that won’t irritate your skin.

Other tips to consider when choosing cool bedding include:

  • Invest in light bed covers – Again, cotton is a good choice, as are natural fabrics. You want to avoid synthetic fabrics, such as polyester, that can turn your bed into a heat trap.
  • Choose a hybrid mattress – While some people complain that memory foam mattresses can be hot, hybrid mattresses are much better at temperature control. This is because, although they have a memory foam surface as mentioned earlier, they have coil layers underneath that keep the air flowing inside the mattress. Some models even have extra cooling layers, such as those made of bamboo, to further regulate temperature while you sleep.

Change The Foundation Of Your Bed

Slatted Bed Base

The reason why you’re feeling hot at night might not be your mattress per se.

The air might be getting trapped underneath your mattress!

A bed frame that creates enough air circulation underneath the bed, such as by being constructed with equally-spaced wooden boards, can help to keep the air flowing around you while you sleep.

If your mattress is currently situated on a solid platform, this can further contribute to it getting hot. A good idea is to choose a slatted base for it or a box spring to encourage air circulation.

Purchase A Water Pillow

Sometimes the problem isn’t that your body’s getting too hot.

Rather, it’s that your head feels hot and that’s making you feel hot all over. If you suspect that this is what’s happening to you, a water pillow can help to keep you cool.

Water pillows contain internal sleeves that can be filled with water, in the same way as a hot water bottle.

You can adjust how much or how little water you put in the pillow, depending on what feels most comfortable when you lie on it.

Although vinyl material protects the mattress from things like stains and sweat, its waterproof nature can make you feel hot during sleep instead of cool you down.

This is especially the case if you’re naturally prone to getting hot at night.

What should you do if you and your partner like to sleep at different temperatures?

If you feel hot but your partner doesn’t, try to sleep with different blankets, such as by using lighter ones and letting your partner have heavier ones.

If that doesn’t work, consider sleeping in separate beds so that you can use different bedding altogether.
