Why sleep temperature matters
Sleep comfort is closely linked to your overall sleep environment. While individual experiences vary, many people find that room temperature, bedding and mattress materials can influence how comfortable they feel throughout the night.
Factors that may affect sleep temperature include:

BEDROOM TEMPERATURE

HUMIDITY LEVELS

MATTRESS MATERIALS

BEDDING AND SHEETS

SLEEPWEAR
WHETHER YOU SHARE A BED WITH A PARTNER
For warm sleepers, choosing a mattress with breathable materials and moisture-management technologies may help support a more comfortable sleep experience.
What to look for in a temperature-regulating mattress
Not all mattresses manage heat and moisture in the same way. If you tend to sleep warm, there are several features worth considering.

BREATHABLE MATERIALS
Materials that encourage airflow can help create a more comfortable sleep environment and reduce heat build-up around the body.

MOISTURE MANAGEMENT
Moisture-wicking fabrics are designed to draw moisture away from the sleep surface and contribute to a more comfortable sleep climate.
COMFORT PREFERENCE
The way a mattress contours to your body can also affect your sleeping experience. Choosing the right comfort level remains just as important as selecting temperature-regulating features.

CONSIDER YOUR BEDDING
Your mattress is only one part of the sleep system. Breathable bedding, natural-fibre sheets and appropriate room ventilation can all contribute to a more comfortable night’s sleep.
Your mattress is only part of the sleep environment
While your mattress can contribute to a more comfortable sleep climate, several other factors can affect how warm you feel during the night.
Consider the following to help create a cooler sleep environment:
- Choosing breathable bedding and sheets
- Improving bedroom airflow
- Managing room temperature
- Selecting lightweight sleepwear
- Adjusting bedding with the seasons
Together, these factors can help create a bedroom environment designed for comfort throughout the year.
