Best Mattress For Hot Sleepers

Are you a hot sleeper? We’ve all been there; tossing, turning, and sweating through our pyjamas, pillows and bedsheets. When we think of hot sleepers, we think of roasting hot weather when we’re on our holidays; or indeed, that warm two weeks of summer we get in Ireland! 

However, warm weather is not the only cause for feeling extremely hot at night time, there are various reasons one might feel too hot in bed. In this post we will discuss some of these causes and help guide you towards the best mattress for hot sleepers.

What is a Hot Sleeper?

So, what exactly is a hot sleeper? A hot sleeper is someone who consistently feels hot during the night while in bed. They wake up drenched in sweat, and frequently, this leads to disrupted and uncomfortable sleep. 

This can occur regardless the weather or bedroom being hot. In the next section we look at the possible causes of being too hot to sleep and what, aside from choosing the best mattress for a hot sleeper, you can do to make your night’s sleep more comfortable and cool.

What causes "hot sleeping"?

The root causes of being too hot so sleep can typically be categorised as either physiological or environmental. Here, will have a quick look at some examples of both:

Physiological Factors

  • Women may experience being too hot due to the effects of menopause
  • Anxiety can be a factor
  • There are some medications which cause night sweats e.g.  some anti-depressants, steroids and painkillers
  • If you suffer from hypoglycaemia (low blood sugar)
  • If you are developing a high temperature as a result of another illness or condition
  • If you suffer from nightmares


Environmental Factors

Your Bedroom

How do you set up your bedroom for a good night's sleep? Do you prefer the curtains open or closed?

Ensuring that your curtains and blinds are closed at night, and during the day when in summer, can have a positive impact. In summer it can help lower the indoor temperature, offering a cooler and more comfortable sleep environment.

Hot sleepers should consider cracking open a window if you're comfortable with it; it will enhance the room's ventilation. However, if you struggle with hay fever or dust sensitivity, this may not be the best option.

Your Sleepwear/Pyjamas

In Ireland, we often gravitate towards cosy, fluffy pyjamas to stay warm, especially with our cooler climate. But if you're a hot sleeper/someone who tends to feel too warm during sleep, it's a good idea to opt for lighter pyjamas made from breathable fabrics like silk or cotton.

Your Bedding

It should go without saying, but if you have a decorative throw and lots of lovely cushions on your bed, ditch them at night time!

Extra layers insulate the heat which would not be helpful for hot sleepers. It is worth keeping in mind what Tog your duvet is also. 

The most popular tog ratings are 13.5 for winter months, 10.5 for spring and autumn and then 4.5 for summer time. Most people only use one duvet for all year round, in this case a 10.5 tog duvet is best for most sleepers.

Your Mattress

Choosing the right mattress important for hot sleepers. If your mattress holds onto heat, it can make you even hotter, leading to uncomfortable nights and poor sleep quality.

The best mattress for hot sleepers should help release body heat and let air flow. Some materials like memory foam can trap heat, so it's good to look for mattresses with cooling features like gel-infused foam or breathable latex or simply stick with traditional pocket sprung style mattresses.

By picking a mattress that keeps you cool, you can sleep better, feel more comfortable, and wake up more refreshed.
