What Bedding Helps You Sleep Cooler?

Last Updated: April 2026

If you often feel too warm during the night, your bedding may be contributing to the problem. Bedding that traps heat can make it harder for the body to regulate temperature, which may lead to restless sleep or frequent waking.

Choosing breathable bedding materials can help improve airflow and reduce heat build-up around the body. Certain fabrics are designed to wick moisture away and allow heat to escape, helping maintain a more comfortable sleeping temperature.

In this guide, our Bed and Mattress Experts explain which bedding materials may help keep you cooler during the night and how bedding choices can influence sleep comfort.

Why Bedding Can Affect Sleep Temperature

During sleep, the body naturally releases heat and moisture. If bedding materials trap that warmth, it can create a hotter sleeping environment.

Bedding that allows airflow and helps manage moisture can support the body’s natural temperature regulation throughout the night.

Several factors influence how bedding affects temperature, including:

fabric breathability
moisture-wicking properties
bedding thickness
the number of bedding layers used

Choosing materials designed for airflow can help improve night-time comfort.

Cotton Bedding

Cotton is one of the most popular bedding materials because it is naturally breathable and soft.

Cotton fibres allow air to circulate through the fabric, which helps reduce heat build-up during sleep. Cotton bedding can also absorb moisture, helping maintain a more comfortable sleeping surface.

Lightweight cotton sheets are often a good option for sleepers who tend to feel warm during the night.

Bamboo Fabrics

Bamboo-based bedding is known for its moisture-wicking properties and breathability.

Bamboo fibres can help draw moisture away from the body while allowing airflow through the fabric. This can help regulate temperature and reduce the feeling of heat during sleep.

Because of these properties, bamboo bedding is often chosen by sleepers who experience night-time overheating.

Wool Bedding

Although wool may seem warm, it is actually one of the most effective natural temperature-regulating materials.

Wool fibres help regulate body temperature by:

allowing air to circulate
absorbing moisture
releasing heat when the body becomes too warm

This ability to manage both heat and moisture makes wool a popular material in temperature-regulating bedding.

Breathable Mattress Protectors

Mattress protectors can also influence sleep temperature. Some protectors are designed with breathable fabrics that help maintain airflow while protecting the mattress from spills and moisture.

Using a breathable protector can help maintain mattress hygiene without trapping heat around the sleeping surface.

Cooling Pillows

Pillows also play an important role in regulating sleep temperature, particularly because the head and neck release a significant amount of body heat.

Pillows designed with breathable materials or ventilation systems can help improve airflow around the head and neck, helping sleepers stay cooler during the night.

Expert Advice from Land of Beds

Bedding plays a significant role in overall sleep comfort. Choosing breathable materials such as cotton, bamboo, or wool can help support better airflow and temperature regulation during sleep.

At Land of Beds, our experts recommend considering the entire sleep setup, including mattresses, pillows, and bedding materials, to create a comfortable and balanced sleep environment.
