New Sleep Number Research Shows Adjusting Bed Temperature Can Add Up to Nearly an Hour of Sleep Per Night

Large-scale study presented at SLEEP 2026 explores how personalized temperature features can help people sleep longer 

Getting the right temperature at night is key to sleeping well. The body relies on a natural cooling process to initiate and maintain sleep. As core temperature drops, the skin warms to help dissipate heat, creating the right conditions for rest, but things like room temperature, bedding and physiology can disrupt that balance. Sleep Number’s temperature technology, like that found in its Climate™ collection, is designed to help solve this by adjusting the bed’s temperature throughout the night, helping keep sleepers comfortable. For example, the Climate360® and ClimateCool® beds cool up to 20x faster than a leading competitor* and previous analysis shows Climate360 users get 52.5 minutes more restful sleep per night.** 

 

“Temperature has a powerful impact on your comfort and your sleep,” said Melissa Barra, Sleep Number’s EVP and Chief Product, Strategy and Technology Officer. “As a leader in temperature innovation, we designed our beds to adjust with you through the night—helping you sleep up to 15 degrees cooler or warmer on each side—so you stay comfortable and wake up feeling more rested. This research shows how mattresses are evolving, and how personalized comfort that adapts to you can help improve sleep and wellness over time.” 

 

In one of the largest real-world sleep studies of its kind, Sleep Number researchers analyzed sleep data from nearly 82,000 people across more than one million sleep sessions gathered directly from Climate360 sleepers in their home. The study looked at how using the Climate360 bed’s different temperature settings and adjustments throughout the night influenced sleep patterns  

 

The data showed that by adjusting the temperature of the mattress, sleep duration increased by more than 52 additional minutes per night compared with those who did not adjust temperature. The most effective approach gently warms the bed early in the night to promote heat loss from the body and support the natural drop in core body temperature then later cools the sleeper by actively drawing warm air away from their body to align with the body’s natural sleep cycle. Together, these findings provide strong, population-scale evidence that dynamic temperature control is an effective, science-backed way to improve sleep.
