Eight Sleep, the world’s first sleep fitness company, today announced Pregnancy mode, a new Autopilot feature that uses AI to support sleep from the first trimester through twenty-four weeks postpartum.
Applying AI to help women sleep better
Autopilot is Eight Sleep’s AI system, powering the Pod’s ability to personalize sleep temperatures automatically. It analyzes each member’s unique sleep patterns, biometrics, and environment to adjust temperature, elevation, alarms, and other interventions throughout the night, helping improve sleep without any manual input.
Pregnancy changes sleep early as the first trimester and sleep is impacted well into the postpartum period. As the body changes, so do sleep patterns, temperature needs, heart rate, HRV, breathing, and recovery. Yet most sleep products are still designed around a static body, leaving women to manually adjust their environment through one of the most physically demanding life stages.
Pregnancy mode changes that. Once activated in the Eight Sleep app, Autopilot recalibrates around a member’s pregnancy stage and pre-pregnancy metrics, automatically adjusting Pod temperature recommendations each night as the body’s needs evolve. The feature also surfaces pregnancy-specific insights for biometrics, including resting heart rate, HRV, breath rate, sleep stages, and snoring, helping members understand how their sleep and recovery are changing week by week compared to their pre-pregnancy baseline.
“Pregnancy changes a woman’s body every week, but most sleep products treat her like nothing has changed,” said Alexandra Zatarain, Co-founder and VP of Brand and Marketing at Eight Sleep. “Pregnancy Mode moves beyond tracking to action, helping the Pod adapt her sleep environment in real time from the first trimester through postpartum.”
Built on 45,000 nights of pregnancy and postpartum sleep data
Pregnancy Mode is powered by Eight Sleep’s Women’s Sleep Initiative, a multi-year research program focused on understanding how sleep changes across the female lifespan. The initiative has analyzed more than 344,000 nights of sleep from over 5,000 women, with research spanning the menstrual cycle, pregnancy, menopause, and hot flashes.
The data shows that pregnancy leads to clear, measurable changes in temperature needs. By the third trimester, that pattern reverses: women consistently set the Pod approximately 3°F cooler than before pregnancy, as the demands on the body rise. Temperature preferences typically return close to pre-pregnancy by about eight weeks postpartum.
Pregnancy mode uses these patterns, combined with each member’s own temperature baseline, to personalize temperature recommendations throughout pregnancy and postpartum.
“Women’s sleep is not broken. Sleep environments simply have not been designed for female physiology,” said Dr. Nicole Moyen, Senior Director of Science and Clinical Research at Eight Sleep. “Pregnancy is the clearest example of that. The body is changing every week. Pregnancy Mode allows the Pod to respond to those changes automatically in support of better sleep.”
Personalized insights for every stage of pregnancy
In addition to temperature adjustments, Pregnancy mode introduces dedicated insights inside the Eight Sleep app. Each week, members can see how key biometrics are changing relative to their own pre-pregnancy baseline and what is typical for their stage of pregnancy. People with Pregnancy mode active will also receive a personalized daily insight supported by Autopilot 4.1, Eight Sleep’s AI model optimized for a pregnant population.
These insights include changes in sleeping heart rate, HRV, breath rate, sleep stages, and snoring. Pregnancy mode is also compatible with Hot Flash mode for members experiencing pregnancy-related hot flashes.
Pregnancy mode launches as part of Autopilot 4.1, Eight Sleep’s second major AI release of 2026, following the introduction of its Sleep Agent in April.

Pregnancy mode begins rolling out on May 10th to all subscribed Eight Sleep members through the Eight Sleep app on iOS and Android.
