Does your sport change how you sleep? Here’s what Eight Sleep athlete data revealed
Contributed by Natasha Ragland, MS 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 […]

Sleep debt: what it is, how it builds, and what it costs you
Contributed by Emma Tracy 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 […]

Spring Forward with Eight Sleep: A Science-Backed DST Guide
Contributed by Megan Holm, M.S. 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 […]

Sharing a bed with a partner improves cardiovascular recovery during sleep
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 […]

BTS: How Eight Sleep ran one of the most comprehensive studies on women’s sleep
Contributed by Megan Holm, M.S. 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. […]

Liquor, wine, or beer? Here’s how each affects your recovery
Contributed by Elias Malek, PhD 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 […]
