What fabric keeps you coolest in bed?

For many people, getting a good night’s rest can be a challenge on hot summer nights. Finding the right bedding materials can make all the difference in sleeping comfortably through the night. In this article, we’ll explore the science behind staying cool in bed and the different types of bedding fabrics that keep you comfortable all night long.

The Science Behind Heat Retention in Bedding Materials

Heat retention in bedding materials is a critical factor in determining how cool or warm you feel while sleeping. Our bodies experience different temperature changes throughout the night, and the right bedding material can help regulate our body temperature and keep us comfortable. The key to staying cool in bed lies in selecting the right fabric that allows air to circulate and wicks away moisture from the skin.

Studies have shown that natural fibers such as cotton, bamboo, and linen are excellent choices for bedding materials as they are breathable and absorbent. These materials allow air to circulate freely, preventing heat from getting trapped and keeping you cool throughout the night. Additionally, they are highly absorbent, wicking away moisture from the skin and preventing sweat from accumulating, which can lead to discomfort and overheating. So, if you’re looking for a comfortable and cool night’s sleep, consider investing in bedding made from natural fibers.

The Different Types of Bedding Fabrics and Their Cooling Properties

When it comes to choosing the right type of bedding fabric for staying cool, it’s essential to know the properties of each material and how they affect your sleep. Let’s look at some of the most common materials used in bedding and their cooling properties.


Cotton is an excellent cooling bedding material because it is breathable and wicks away moisture from the skin. Its natural fiber composition also allows it to circulate air easily, keeping you cool all night long. However, the type and quality of cotton used can make a considerable difference in its cooling properties. A high-quality cotton with a lower thread count will be more breathable and offer a fresh and cool feeling through the night.


Next to cotton, linen fabric is a popular choice for cooling bedding materials. It is lightweight and breathable, making it an ideal material for summer months. Linen also has moisture-wicking properties that can help regulate body temperature and prevent skin irritation.


Silk is a luxurious and breathable fabric that is ideal for staying cool in bed. It is incredibly lightweight and allows air to circulate around the body efficiently. Silk also has moisture-wicking properties that help keep the skin dry and prevent sweating.


Bamboo is a newer introduction to the bedding industry, and it has many cooling properties. It is a breathable and lightweight fabric that wicks away moisture from the skin, keeping you dry and cool. Bamboo material is also resistant to odors, which can help keep your bedding fresh and cool.


Tencel is a type of fabric made from eucalyptus trees and is known for its cooling properties. It is incredibly soft and lightweight, making it an excellent choice for hot summer nights. Tencel also has moisture-wicking properties that help regulate body temperature and keep you dry throughout the night. Additionally, it is eco-friendly and sustainable, making it a popular choice for those who prioritize environmentally conscious products.

Why Natural Fibers Like Cotton and Linen Are Ideal for Cool Sleep

Natural fibers are the best choice when it comes to bedding materials, especially for people who sleep hot. They are breathable and allow air to circulate around the body, which helps regulate temperature and create a comfortable sleeping environment. Natural fibers are also more absorbent than synthetic materials, making them perfect for wicking away moisture from the skin, keeping you cool and dry all night.

In addition to their cooling properties, natural fibers like cotton and linen are also environmentally friendly. These materials are biodegradable and renewable, making them a sustainable choice for bedding. Choosing natural fibers over synthetic materials also reduces the amount of plastic waste that ends up in landfills and oceans. By opting for cotton or linen bedding, you can sleep comfortably and feel good about your impact on the planet.

The Benefits of Breathable Fabrics for a Comfortable Night’s Sleep

Flip your pillow over to the cool side, isn’t it a relief? That’s the power of breathable fabrics. Breathable fabrics create a comfortable sleeping environment that promotes quality rest by allowing air to circulate and moisture to evaporate away from the body. Choosing breathable fabrics for your bedding ensures a more comfortable and restful night’s sleep.

How Thread Count Affects the Breathability of Bedding Materials

Thread count is the number of threads woven into one square inch of fabric. A higher thread count usually means a softer, smoother fabric. However, when it comes to cooling bedding materials, a high thread count can actually make the fabric less breathable. A high thread count means the fibers are densely packed together, reducing airflow and making it harder for the material to wick away moisture. To stay cool in bed, look for bedding with a lower thread count, around 300-400, to ensure maximum breathability and optimal air circulation.

Top Cooling Bedding Brands and Products to Try Out

There are many cooling bedding products available on the market that can help keep you cool and comfortable all night. Some of the best brands to consider are Casper, Cozy Earth, Slumber Cloud, and Saatva. Additionally, there are many other materials and products to try out, such as cooling mattress pads, pillows, and sheets that are specifically designed to maintain a comfortable sleep temperature.

Tips for Selecting the Best Cooling Bedding Material for Your Needs

Selecting the best cooling bedding material starts with understanding your needs and preferences when it comes to sleeping. Consider your sleep habits and comfort level when selecting your bedding material. Factors to consider include the type of sleeper you are, room temperature, and budget.

Other Factors That Affect Your Sleep Temperature

While bedding plays a critical role in maintaining a comfortable sleep temperature, other factors play an essential role, too. Room temperature and humidity have a direct impact on your sleep, so ensure you keep your bedroom cool and well-ventilated. Using a fan or air conditioning can help combat the heat and humidity, allowing you to sleep more comfortably. Additionally, your choice of sleepwear has an impact on your sleep temperature. Choose breathable, lightweight clothing, such as cotton or moisture-wicking fabrics.

How to Keep Cool in Bed Without Changing Your Sheets

If you’re not ready to make the switch to new bedding materials, several other tips can help keep you cool in bed. For instance, take a cool shower before bed or use a cooling pad or ice pack on your feet to reduce body temperature. Try turning off all electronic devices and limiting your exposure to blue light before bedtime. Finally, remember to stay hydrated during the day and avoid consuming caffeine or heavy meals before sleep to help regulate your body temperature.


Staying cool in bed is essential for ensuring a comfortable and restful night’s sleep. By selecting the right bedding materials, practicing good sleep hygiene, and staying hydrated, you can achieve a more comfortable and cool sleep environment. Remember to choose natural and breathable fabrics, such as cotton and linen, with a lower thread count, to ensure maximum air circulation and moisture-wicking properties. With these tips, you can finally say goodbye to sleepless hot summer nights and hello to a peaceful and cool slumber.
