For millions of women, sleep can become a nightly battle during perimenopause and menopause. The culprit? Hot flashes. These sudden surges of heat and sweating can strike multiple times a night, disrupting rest, increasing wake time, and leaving you groggy and unrefreshed by morning.

At Eight Sleep, we believe exceptional sleep should be possible through every stage of life. That’s why Pod 5 was engineered with women’s unique needs in mind—starting with its personalized temperature control.

The science of hot flashes and how they disrupt sleep

The onset of hot flashes during menopause are linked to changes in the brain caused by declining estrogen levels. However, the exact triggers of menopausal hot flashes have yet to be discovered. . Regardless, hot flashes often lead to repeated awakenings, drenched sheets, and a restless night.

According to the Sleep Foundation, up to 85% of women experience hot flashes during menopause, and nearly half of these women report that hot flash episodes severely interfere with their sleep quality.

Pod 5: Precision cooling when you need it most

Pod 5 offers an unmatched solution by continuously monitoring your biometrics—including heart rate and respiratory rate—through passive sensors embedded in the Pod and the new hydro-powered Blanket.

Research finds the Pod can boost sleep and cardiovascular metrics with real-time temperature adjustments based on your sleep stages

Did you know that the temperature of your bed can make a big difference in how well you sleep throughout the night? Temperature is a key factor in regulating sleep, and being able to adjust your bed temperature throughout the night can improve heart rate (HR), heart rate variability, deep sleep, and REM sleep.  Until now, no studies have explored whether adjusting bed temperature for each specific sleep stage could help you spend more time in that stage. However, Eight Sleep is committed to uncovering the science behind how temperature influences sleep and health, thereby supporting the continuous refinement of its proprietary algorithm, Autopilot.  How does Autopilot work?  Autopilot is the intelligence behind the Pod, a set of AI algorithms that refine a user’s sleep environment based on their personal needs and variations of their body, habits, and environment. For example, it adjusts the bed temperature based on the body’s different temperature needs during deep and REM sleep. Each night, Autopilot applies temperature offsets to the user’s selected temperatures to promote more time in deep and REM sleep – cooler offsets promote deep sleep and warmer offsets promote REM sleep. Additionally, if the user had low deep sleep (<15% of the night) or REM sleep (<20% of the night) the previous night, Autopilot will increase the magnitude of the temperature offset to further promote increased time in deep and REM sleep stages. A new research study presented by Eight Sleep’s Clinical Research team at the SLEEP 2025 conference in Seattle, WA reveals that the latest version of Autopilot, is the first to make real-time, sleep stage-based temperature changes throughout the night, resulting in cardiovascular and sleep benefits.  How researchers tested the Pod’s impact Researchers studied 34 individuals who completed at least 7 nights each sleeping without the Pod and then with the Pod using…
