The Science of Cool: How Temperature Affects Your Sleep Quality

Don’t you hate it when you wake up in sweat? Do you feel like you don’t sleep well during the summer months? The temperature of your bedroom and the bedding you have has a huge impact on the quality of rest you enjoy. But, not everyone takes this seriously, which leaves them in a low mood, feeling tired and having an unproductive day. Let’s dive in and take a closer look at how temperature affects your sleep quality and what you can do about it.

The Ideal Sleep Temperature

Have you ever wondered why you wake up in a cold sweat or shiver under the sheets? The ideal room temperature for a good night’s sleep is like the Goldilocks principle—it shouldn’t be too hot or too cold. We’re talking about that sweet spot between 60 to 67 degrees Fahrenheit (15.5 to 19.5 degrees Celsius).

Many people don’t realize how important the temperature is for good sleep. Namely, it’s something that can help regulate circadian rhythm. When the temperature starts to get cooler in the evening, the body realizes that this is the right time to sleep. This is something that’s thrown off course if you’re too hot.

Let’s not forget that temperature affects how comfortable you feel. When you’re too hot, you will wake up more and toss and turn. Generally, you don’t get good rest, which leads to you feeling sluggish and grumpy the next morning. Night sweats are more common than you think.

Cooling Sleep Technologies

Now that we’ve laid the groundwork, let’s talk tech. Cooling mattresses, pillows that keep you chill—there’s a whole world of sleep tech designed to turn your bed into a cool haven. We’ll break down the latest innovations and help you decide if it’s time to upgrade your sleep game.

Bamboo Sheets

Something that’s grown in popularity in recent years is bamboo sheets. Not only is this a soft and comfortable material, but it’s also cooling and regulates body temperature. Currently, the favourite bamboo sheets for many people are from Hush. They’re made from pure bamboo, which feels luxurious to sleep in. There’s a 30-night trial you can enjoy to see if you get a more restful night.

Smart Mattresses

Did you know that there are now smart mattresses? They have a temperature control system you can adjust to ensure that you have the right temperature. While they can be expensive, some people sweat so that they get a better night’s sleep.

DIY Cooling Strategies

Not everyone has the budget for high-tech sleep gear, and that’s okay. We’ve got your back with some down-to-earth, do-it-yourself tips for creating a cooler sleep environment. 

Strategic Fans

A fan can be just what you need when the bedroom is too warm. Ensure that the fan is facing you while you sleep. This can create a cooling breeze, assisting in a comfortable temperature.

Open Windows

During the day, the house temperature will increase. But, at night, this is when the temperature goes down outside. You can take advantage of this by opening windows in the evening. If it’s safe and secure, you can leave a bedroom window open overnight. There are meshes you can use to keep bugs out.

Seasonal Adjustments

Just as you swap out your wardrobe with the seasons, your sleep routine may need a seasonal refresh too. We’ll guide you on how to adapt your sleep environment to the ever-changing weather. It’s time to bid farewell to those sweaty summer nights and chilly winter mornings.

Light Materials in Summer

The summer means hotter temperatures, which can lead to uncomfortable rest if you’re not careful. During the summer, choose lighter materials that are cool and breathable. Bamboo is a good option since it’s cool to the touch and helps to regulate body temperature.

Warmer Bedding in Winter

When the temperature dips in the winter, you need to ensure your bedding keeps you warm and cozy. You should opt for heavier materials that are able to retain heat. This can include fleece or cotton.

Change Your PJs

Don’t forget that it’s not just the bedding that keeps you warm or cool. You also have to think about your PJs. They’re directly against your skin and impact how you feel. Often, people feel most comfortable in cotton. This is breathable, and you can get longer PJs for the winter and shorts for the summer.


And there you have it, the cool lowdown on how temperature and sleep quality are best friends. Experiment with different temperature settings, embrace the tech, or go old-school with DIY strategies. Your journey to a better night’s sleep starts with finding the perfect temperature balance.
