Whether you prefer to sleep in a hot or cold room is a matter of personal preference, but there are some benefits to sleeping in a cold room. A cooler room can improve sleep quality by stimulating melatonin production, a hormone that is produced in response to darkness and cold, helping the body fall and stay asleep. Additionally, sleeping in a cold room can lower your body's core temperature, which can boost melatonin and serotonin levels, improving mood and sleep quality. The ideal sleeping temperature ranges between 60 to 68 degrees Fahrenheit, and during those temperatures, it can be easier to fall into a deep and restful sleep. However, sleeping in a cold room may not be comfortable for everyone, and it is important to consider individual preferences and ensure that the room is not too cold, as this could inhibit the body's ability to fight illness and regulate body temperature.

What You'll Learn

Ideal room temperature for sleep
The ideal room temperature for sleeping is generally considered to be between 60°F and 68°F (15.6°C and 20°C). However, this can vary from person to person, and some people may prefer a slightly warmer or cooler environment. Sleeping in a cooler environment is often recommended as it can promote deeper and more sound sleep. Our bodies naturally lower their core temperature by up to 2 degrees during sleep, so a cool room can facilitate this process and help maintain sleep throughout the night.
There are a few ways to ensure your room stays within the ideal temperature range. Firstly, you can set your thermostat to the desired temperature, or slightly warmer during the day, and cooler at night. You can also open windows or use air conditioning or fans during warmer months to keep the room temperature comfortable.
The type of bedding and mattress you use can also impact your sleep temperature. Heavier blankets and comforters may be too warm for some people, especially during the summer months. It is recommended to use lightweight bedding and swap heavy blankets for lighter ones to stay comfortable. Additionally, memory foam mattresses tend to retain heat, so they may be better suited for those who sleep cold. In contrast, mattresses with cooling technologies, such as gel-infused foam, graphite, or hybrid beds with innerspring coils, are better for hot sleepers.
It is important to understand your sleep preferences and patterns, which are influenced by factors such as genes, lifestyle, environment, and health. Knowing whether you are a hot or cold sleeper can help you create a sleep environment and routine that suits your needs. For example, hot sleepers may benefit from cooling pillows, which use gel to draw heat away from the head, promoting better sleep quality. On the other hand, cold sleepers might prefer electric blankets to stay warm and cosy.
Ultimately, the key to getting quality sleep is finding a sleep routine and environment that works for you and helps you feel rested. Making small adjustments to your sleep environment and experimenting with different temperatures can help you find your ideal sleep sweet spot.

Mattresses for hot and cold sleepers
Whether you're a hot or cold sleeper, your mattress can play a crucial role in regulating your body temperature and ensuring you get a good night's rest. Here are some factors to consider when choosing a mattress that suits your sleeping temperature:
Mattress Type
The type of mattress you choose can significantly impact your sleeping temperature. Memory foam mattresses, for instance, tend to retain heat due to their dense structure, making them better suited for cold sleepers. On the other hand, hybrid mattresses that combine memory foam with coils offer improved breathability and airflow, making them a good option for hot sleepers. Latex mattresses are also recommended for hot sleepers as they are more breathable than traditional memory foam.
Cooling Technologies
If you're a hot sleeper, look for mattresses with advanced cooling technologies. Some mattresses are infused with gel, graphite, or Phase Change Materials (PCM) that draw heat away from your body and help regulate temperature. The Brooklyn Bedding Aurora Luxe, for example, features gel infusions and phase change materials that adapt to your surroundings to provide a cooler sleeping surface. The Nectar Luxe Hybrid is another highly-rated option, with a quilted cooling cover that provides immediate temperature relief.
Firmness and Support
The firmness and support of a mattress can also affect how cool or warm you feel while sleeping. Firmer mattresses, like the DreamCloud Original, often provide better airflow and breathability by creating more space for air to circulate. Softer, plush mattresses tend to conform more closely to the body, which can sometimes trap heat. However, some softer mattresses, like the Tuft & Needle mattress, have graphite and gel infusions that help draw away heat, providing a comfortable sleeping temperature.
Personal Preferences and Adjustments
Ultimately, the best mattress for you will depend on your personal preferences and sleeping habits. Consider experimenting with different bedding types, such as thinner sheets or additional blankets, to find what works best for you. Additionally, factors like clothing, thermostat settings, and room ventilation can also be adjusted to create a more comfortable sleeping environment.
Remember, understanding your sleeping temperature is crucial to constructing a sleep routine and environment that suits your needs. By choosing a mattress with the right features and making simple adjustments, you can improve your sleep quality and wake up feeling rested.

Bedding for hot and cold sleepers
Whether you're a hot or cold sleeper, the right bedding can help you get a good night's rest.
Bedding for Hot Sleepers
If you tend to sleep hot, look for bedding that promotes airflow and breathability. Sheets made from materials like percale, Tencel, or eucalyptus are good options, as they have a tighter weave that promotes air circulation and wick away moisture. Linen sheets are also a good choice for hot sleepers, as they are lightweight and breathable. Look for sheets with a high thread count, like the Sol Organics percale sheets, which have a thread count of 300. Sheets made from bamboo viscose, such as the Quince Bamboo Sheet Set, are another great eco-friendly option, as they use far less water than cotton sheets.
In addition to sheets, hot sleepers may want to invest in a cooling mattress or mattress topper. Hybrid mattresses or those made with latex, gel, or graphite can help regulate temperature and keep you cool. Cooling pillows can also help, as they use a gel that draws heat away from your head.
Bedding for Cold Sleepers
If you're a cold sleeper, you'll want bedding that traps heat and creates a warm sleeping surface. Traditional memory foam mattresses retain heat, so they can be a good option for cold sleepers. Electric blankets can also help keep you warm, as can thicker sheets and comforters.
General Tips for Hot and Cold Sleepers
- Set your thermostat between 60 and 65 degrees Fahrenheit. This temperature range is ideal for promoting sleep, according to experts.
- Consider your clothing. Wearing lighter or thicker clothing to bed can help regulate your temperature.
- Exercise can help regulate your body temperature. Working out 3-4 hours before bed and taking a hot shower 1-2 hours afterward can promote melatonin production and help you sleep.
- Seal windows and doors to keep warm air from escaping and cold air from entering.
- Cuddle with a partner or pet to make use of their body heat.
Ultimately, the key to getting quality sleep is finding a routine and sleep environment that works for you. Experiment with different bedding options and temperature settings to determine what helps you feel rested.

Clothing for hot and cold sleepers
The ideal temperature for sleep is between 60 and 68 degrees Fahrenheit. However, this can vary from person to person, and some people may prefer a slightly warmer or cooler environment. Keeping your bedroom on the cooler side can improve sleep quality as it reinforces your body's natural instinct to sleep.
If you are a hot sleeper, you may find yourself kicking off the blankets or wanting to sleep with a fan or the window open. In this case, it is recommended to lower the temperature in your room at night and use curtains to block sunlight during the day. You should also wear lighter clothes to bed and consider swapping heavy blankets for lighter bedding.
If you are a cold sleeper, you may feel chilly or shivery at night. In this case, you should try wearing socks or silk pyjamas to bed and using an extra blanket to warm up. You may also want to cuddle up with a partner or pet to make use of their body heat.
Other tips to regulate your body temperature while sleeping include:
- Taking a warm shower or bath before bed as this can stimulate your body to cool down on its own and help you relax.
- Exercising 3-4 hours before bed to raise your body temperature, followed by a cooling-down period before sleep.
- Wearing dry, loose-fitting clothing to bed to trap warm air near your skin.
- Unzipping your sleeping bag or using a lighter blanket if you start to sweat.
- Sleeping in your underwear or long underwear in a sleeping bag to stay warm.

How to cool down or warm up your room
How to cool down your room:
To cool down your room, try to keep your windows closed during the day, especially when the sun is shining directly into your room. You can also use curtains with thermal protection or portable blackout blinds to keep the heat out. Opening the windows at night or when it's cooler outside can help let in a breeze and cool down your room. Using fans, ceiling fans, or air conditioning can also help circulate cool air and lower the temperature in your room. Additionally, you can use natural fibres like cotton, linen, or bamboo for your bedding and clothing, as they are more breathable and can help keep you cool.
How to warm up your room:
To warm up your room, start by checking your vents and radiators to ensure they are open and unobstructed. Furniture and rugs can block airflow, so rearranging them might be necessary. If you have a hot-water radiator, check for trapped air and release it by opening the small valve at the top. Sealing windows and doors can help prevent heat from escaping. Thick curtains, wall blankets, and rugs can also help insulate your room and trap warmth inside. Electric heaters or electric blankets are also an option, but they can be costly and may not distribute heat evenly.
Tips for better sleep:
Regardless of whether you tend to sleep hot or cold, finding a sleep routine that works for you is essential for getting quality rest. Adjusting the temperature in your room, changing your bedding and clothing, and experimenting with different sleep setups can all help improve your sleep quality. Additionally, exercising earlier in the day and taking a hot shower a few hours before bed can promote better sleep by taking advantage of your body's natural temperature drop during sleep.
