Eight Sleep Pod Leads to Improved Sleep Quality

& Sofie Jacobsen, M.S. New research & what it contributes Eight Sleep Labs announced findings from a new study (available now via preprint). The study characterizes how sleep temperature preferences (using the Pod), sleep, and cardiovascular recovery (heart rate (HR) and heart rate variability (HRV)) change across pregnancy and postpartum. […]

& Sofie Jacobsen, M.S. Pregnancy increases demand on the body: resting heart rate (RHR) increases, heart rate variability (HRV) decreases, sleep becomes more fragmented, and deep sleep declines (source, source, source, source). All of these changes impact morning refreshedness, daytime functioning, and decision-making (source). We wanted to know: does sleeping […]

Every serious athlete knows their sport changes their body. What’s less understood is how different sports change the way they sleep, not just how long, but how deeply, how efficiently, and how well the body recovers between training sessions. Most research on elite athletes and sleep relies on small lab […]

Pregnancy changes your body every week, but until now, your sleep environment stayed the same. Today, Eight Sleep is launching Pregnancy mode, a new feature available with Autopilot. Pregnancy mode automatically adjusts your Pod’s temperature from the first weeks of pregnancy […]

The best time to exercise for sleep is whenever you’ll actually do it. Consistency matters more than timing. Eight Sleep’s mission is to fuel human performance through optimal sleep – but it goes beyond just sleep. Our Performance Windows feature is a good example: it recommends a daily workout window […]

Most people treat sleep as something to squeeze in around everything else. You stay up late, wake up early, and tell yourself you’ll catch up on the weekend. But sleep isn’t a flexible resource, it’s a biological necessity. The gap between how much sleep you need and how much you actually […]

On March 8th at 2:00 a.m., most Americans will lose 1 hour of sleep overnight. While clocks in Hawai’i and most of Arizona stay put, the rest of the country springs forward. Unfortunately, the effects of daylight savings time (DST) go beyond a groggy Sunday morning.  Your pre-DST Plan (March […]

Two-thirds of adults share their bed with a partner, yet few studies have measured how this impacts sleep and recovery (Ref). We analyzed over 238,000 nights of real-world sleep data in more than 4,000 adults who slept with and without their partner. We found that sleeping with a partner increases heart rate variability (HRV) by […]

Sleep science has traditionally relied on short laboratory studies, small sample sizes, and populations that don’t reflect how people actually sleep at home. This is especially true for women in midlife, a group that has been historically underrepresented in sleep research, despite reporting some of the most significant sleep challenges. […]

New research from Eight Sleep Labs Eight Sleep Labs announced findings from a new scientific study (available now via preprint) showing that the Pod by Eight Sleep reduced nighttime hot flashes by 56%, on average, after one week of use.

The effects of alcohol have become a hot topic lately, as we are starting to understand better and recognize just how much it disrupts sleep. However, most studies treat all types of alcohol (beer, wine, liquor, etc) under one umbrella, simply comparing “drinking nights” to “non-drinking nights.” That leaves an important […]

Your body runs on a built-in clock that helps keep everything on schedule: when you feel sleepy or alert, hungry or focused, and even how your digestion and metabolism work. This 24-hour cycle is called your circadian rhythm. When you fly across several time zones, that internal clock can’t reset fast […]

Findings contributed by Clinical Team member Megan Holm, M.S. For years, menopausal women have been told that the negative changes they experience in sleep are normal. In fact, many research studies have highlighted the fact that compared to men of a similar age, postmenopausal women’s sleep is quite good. Our data agree; however, there is […]

Falling asleep quickly sets the tone for your whole night. The less time you spend staring at the ceiling trying to doze off, the more time your body has for the deep, restorative stages of sleep. That’s why we put the Eight Sleep Pillow to the test: can a temperature-controlled pillow actually help you fall […]

Better recovery starts with sleeping on the Pod. In our most recent study in menopausal women and men 45+, we found that core body temperature is lower when sleeping on the Pod, which leads to improved cardiovascular recovery. Key Takeaways Findings show that the Pod reduces core body temperature by 0.2°C (0.4°F) on average during […]

For women, good quality sleep is tightly linked to your body temperature staying within an optimal range throughout the night. But here’s the twist: hormones like estrogen and progesterone shift a lot during different life stages—birth control, pregnancy, and menopause. And when hormones change, so does how your body handles heat. That’s why at Eight […]

If you’re one of the millions of women struggling with hot flashes at night, you know how negatively they impact your sleep quality. By 2030, 1.2 billion women—14% of the global population—will be menopausal, and about 80% of them will experience hot flashes. These sudden surges of heat can make it nearly impossible to get […]

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 […]

Struggling to get a good night’s sleep?

That’s why with Pod 5 Ultra, we’ve taken a bold step forward in tackling snoring, by detecting it passively and mitigating it intelligently. Why […]

When it comes to optimizing your sleep, most people think of blackout curtains, melatonin, or a memory foam mattress. But one of the most powerful levers you can pull to improve your sleep and your recovery is temperature. The Science: Your core temperature drives your sleep cycle Sleep is not passive. It’s an active, biological […]

Better sleep doesn’t just leave you feeling more rested, it can measurably improve your muscular endurance and aerobic fitness.  We recruited 30 new Pod members and measured their muscular endurance and aerobic fitness at three time points: before sleeping on the Pod, and after 2 weeks and 1 month of sleeping on the Pod. At […]

Our recent clinical study indicates that the Pod may improve sleep quality and daytime functioning. To understand the Pod’s long-term effects on behavior and other subjective metrics, we surveyed 470 Pod 4 users at the following timepoints: before Pod use, and then after sleeping on the Pod for 1 week, 2 weeks, 1 month, and […]

Temperature is one of the most powerful and overlooked drivers of sleep quality. Your body naturally shifts its temperature with each change in sleep stage (e.g. REM and deep sleep). When your sleep environment can adapt to these changes, heart rate (HR), heart rate variability (HRV), and sleep quality all improve (blog, publication). The Pod […]

As a part of our new Elite Autopilot tier, Pod owners can now upgrade their software to include Health Check, a new report that surfaces disturbances to breathing and heartbeats, and provides deeper insights into resting heart rate, heart rate variability (HRV), and breath rate trends – including outliers that could indicate illness.
