If you’ve ever kicked off the covers at 2 a.m. or woken up feeling overheated, you’re not alone. Temperature can play a role in how comfortable you feel while you sleep. But cooling isn’t necessarily about feeling cold when you first get into bed—it’s about creating a balanced sleep environment that feels comfortable throughout the night.
If you’re exploring ways to improve your sleep setup, you can browse options like Sleep Number® mattresses to see how different materials and designs approach comfort.
Why Temperature Matters After You Fall Asleep
During sleep, your body naturally experiences changes in temperature. If your sleep surface retains heat or doesn’t adjust as your body changes, it may contribute to discomfort—such as tossing and turning or waking during the night.
That’s why cooling isn’t just about an initially cool sensation. Many people look for materials and technologies that help maintain a more consistent sleep environment over time.
