26.2 miles, 7 majors in 2026. We teamed up with @Strava to take a look at this year’s most iconic finish lines around the world to see which marathon demands the most. (1/2)

More than a third of psilocybin, ketamine, and LSD use logged on WHOOP happens on Fridays and Saturdays. So we looked at the morning after. LSD and ketamine use were associated with bedtimes over an hour later and Recovery scores about 9 points lower. Psilocybin showed smaller changes: 33 minutes later and 2.9 points lower. The takeaway: the night before shows up in your Recovery.

The late nights that turn into stories you'll tell for years. The finish lines that ask everything of you. The moments that leave you exhausted, but feeling more alive than ever. Your data can tell you what those experiences asked of your body. But it can't tell you what they meant to you.

11,733 people. 1.6M+ nights of data. Dogs, cats, kids, and plenty of shared bedrooms. WHOOP research found that co-sleeping barely moved the needle physiologically compared to sleeping alone. The takeaway: share your space with whoever feels right.

There's a bright side to turning back the clocks. ⏰ Last year, WHOOP members gained 28 extra minutes of sleep when daylight saving time ended. The extra morning sunlight has its perks, too. It's linked to better Sleep Consistency, Recovery, and HRV.

You can't “sweat out” a night of drinking. A hard workout might feel like the fastest way to bounce back, but WHOOP research suggests a different approach.

After drinking, members who exceeded their Strain Target had just a 25% chance of green Recovery the following day. Whereas those who stayed within their Restorative Strain target had an 87% chance.

Terrain isn’t a place. It’s a practice. The way you move, make, and push past your own edges. Surfer and artist, Tre'lan Michael, and athlete and biochemistry student, Kayla Roseboro, each explore their own. For them, discovering the world and discovering yourself is the same pursuit.

Today’s the Sports Equinox, the rare day when baseball, basketball, football and hockey all share the spotlight. So which one takes the biggest toll on the body? 🏀⚾🏒🏈
 Basketball. A typical session scores a Strain of 12.9 out of 21, the highest of the four.

Why? Basketball keeps the heart working.
 Players spend 13% of a session in heart rate zones 4–5, compared with 5% for football, 4% for hockey and 2% for baseball. And it builds the most Strain in less time. A typical session runs 65 minutes, vs. 76 for hockey and 79 for football.

Everyone wants to learn how to manage their stress But not all stress is bad. The key is knowing when it’s helping you grow and when it’s wearing you down. This week on the WHOOP Podcast’s Science of Human Performance Series, WHOOP Global Head of Human Performance and Principal Scientist Dr. Kristen Holmes sits down with WHOOP Staff Research Scientist Gregory Grosicki, PhD, MDS to unpack what stress really does to the body. Together, Dr. Holmes and Dr. Grosicki explore the difference between good and bad stress, how stress shows up in your physiology, why your perception of stress matters, and what you can do throughout the day to better manage stress and support your sleep and recovery.
