What You'll Learn
The ideal room temperature for sleep is 60°F to 68°F
The ideal room temperature for sleep is generally considered to be between 60°F and 68°F (15.6°C to 20°C). This range is thought to facilitate REM sleep and help your body regulate its internal temperature, which naturally cools down as you sleep.
Keeping your room within this temperature range can be achieved in several ways. Firstly, you can set your thermostat to the desired temperature before going to bed. You can also use a fan to cool the room if you feel too warm. Additionally, it is recommended to use breathable and lightweight bedding and sleepwear to help your body regulate its temperature more effectively.
While 60°F to 68°F is the ideal range for most adults, infants and older adults may require slightly warmer temperatures. For infants, it is recommended to maintain a room temperature of around 65°F to 70°F (18.3°C to 21.1°C) and dress them in a breathable sleeper and a sleep sack. Older adults may find more comfortable sleep in temperatures between 68°F and 77°F (20°C and 25°C).
It is worth noting that individual preferences and circumstances vary, so adjustments may be needed. Some people may prefer their sleeping environment to be slightly warmer or cooler. However, temperatures above 75°F (23.9°C) or below 54°F (12.2°C) can disrupt sleep for most people.

A warm bath or shower can help you sleep better
While it is generally better to sleep in a cooler environment, a warm bath or shower can help you sleep better. This is because warm water stimulates the body's thermoregulatory system, causing blood circulation from the internal core to the peripheral sites of the hands and feet, which helps to lower the body temperature.
A warm bath or shower can also help you feel more relaxed, which can help you sleep better. Research has shown that bathing or showering one to two hours before bedtime, ideally 90 minutes, helps people fall asleep faster. The ideal water temperature for improving sleep quality is between 104 and 109 degrees Fahrenheit.
It is important to note that the effectiveness of a warm bath or shower in improving sleep may depend on individual preferences and circumstances. While some people may find that a warm bath or shower helps them relax and fall asleep, others may feel more energized after bathing or showering, especially if it is too close to bedtime. Therefore, it is recommended to experiment with different temperatures and timings to find what works best for you.
Additionally, there are other ways to create a sleep environment that aligns with your temperature preferences. For example, you can set your thermostat to a cooler temperature, preferably somewhere between 60 and 68 degrees Fahrenheit, wear lightweight and breathable sleep attire, and use a fan or air conditioning to improve ventilation and increase air circulation in your bedroom.

Sleep in breathable clothing and bedding to regulate temperature
Sleeping in a cooler environment is generally considered better for sleep. This is because the body naturally cools down during sleep, and a cooler environment can facilitate this process, leading to deeper sleep.
To help regulate your body temperature while sleeping, it is important to wear breathable clothing and use bedding that promotes airflow and absorbs moisture. Here are some tips for choosing the right clothing and bedding for a comfortable sleep:
Breathable Clothing
- Choose lightweight and comfortable clothing made from breathable fabrics. Natural fibres like cotton or linen are good choices as they allow air to pass through, keeping you cool.
- Silk pyjamas are another great option as they can regulate body temperature by cooling you down when you're too warm and warming you up when you're too cold.
- If you tend to sweat at night, look for moisture-wicking clothing that draws moisture away from your skin and allows it to evaporate.
- Consider the fabric density. Even breathable fabrics can trap heat if they are too thick or dense. Look for lightweight versions of fabrics like linen, hemp, and Merino wool.
- Blend types can also make a difference. Blends that combine the softness of natural fibres with the responsiveness of other fabrics, such as a hemp/cotton blend, can provide a comfortable and effective solution.
Breathable Bedding
- Invest in bedding made from natural fibres like cotton or linen. These fibres offer more breathability compared to synthetic fabrics like polyester, which can trap heat.
- Lyocell or Tencel, a type of rayon made from eucalyptus trees, is known for its good temperature- and moisture-regulating properties. It is soft, lightweight, and feels smooth, making it a comfortable choice.
- Bamboo is another type of rayon that goes through a similar process as Lyocell. It is also considered soft and cooling.
- Cotton percale sheets are a great option for hot sleepers as they are crisp, lightweight, and airy.
- Linen sheets are very breathable and can trap less heat than cotton. They provide a cool feel but have a natural, textured feel that some people may not prefer.
- Synthetic sheets made with materials like Tencel, lyocell, or Outlast can also provide excellent temperature regulation. These sheets feel smooth and soft, wicking away sweat for a drier, cooler feel.
By choosing breathable clothing and bedding, you can help regulate your body temperature while sleeping, creating a more comfortable and restful environment for better sleep quality.

Use a fan or air conditioning to cool the room
Sleeping in a cool environment is better for your health and can enhance the quality of your sleep. A cooler temperature helps you fall asleep faster, sleep better, and remain asleep throughout the night.
Using a fan or air conditioning is an effective way to cool your room. Running a fan in your bedroom will help circulate the air and improve ventilation. You can point the fan directly at yourself to amplify the cooling effect, and the white noise from the fan may also help you fall asleep faster. If you also have an air conditioner, keeping the fan on will help circulate the cool air.
If you don't have an air conditioner, you can still use a fan to bring in cool air from outside. Open the windows at night to let in cool air and improve ventilation. You can also open the windows during the day and then close the blinds or curtains to keep the sunlight from warming up your room.
Using a fan or air conditioning to cool your room can help you fall asleep faster and improve your sleep quality. However, it is important to note that individual preferences vary, and you may need to adjust the temperature to find your comfort zone.

A cooling pillow can help lower your brain temperature and improve sleep quality
Sleeping in a cool environment is generally better for sleep quality. A person's body temperature decreases before sleep, and a cool environment can help facilitate this. The ideal room temperature for sleep is between 60°F and 68°F (15.5°C and 20°C). Temperatures above 75°F (23.8°C) and below 54°F (12.2°C) can disrupt sleep.
Some people may find that their pillow doesn't stay cool throughout the night. Water-based pillows, for example, will eventually absorb your body heat until an equilibrium is reached, at which point the cooling effect stops. Memory foam pillows can also be dense, restricting airflow and causing them to absorb and retain body heat. Buckwheat pillows, on the other hand, may not feel immediately cool, but they maintain a comfortable temperature throughout the night without warming up.
Cooling pillows can be expensive, with most costing over $100. However, there are more affordable options available, such as the Slumber Cloud pillow, which impressed testers with its cooling effects and comfortable feel. The HIMOON Bed Pillows are another affordable option that maintains its height and offers good air circulation.
