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 er 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.

Tell us: What WHOOP feature could you genuinely not live without?👇👀

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.

Going ALL-IN…

Thanks to @Jason for having me on this week. I’ve been listening to the @theallinpod for years, so it was awesome to join him.

The best part was actually hearing Jason share his own experience with @WHOOP, including how a change in his health data prompted him to go to the ER, which fortunately he’s fully recovered from. x.com/theallinpod/st…

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.

23 seasons since his first game.
A decade of data.
One more win.

That feeling when you partner with the king 👑

@WHOOP 🤝 @KingJames

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.

Recovery isn't always about doing more.

After a night of drinking, choosing restorative activity over an intense workout may give your body a better chance to bounce back.

Know when to push and when to recover.

It’s official. @WHOOP 🤝 @KingJames

23 enters his 24th season. Still a force. Always measured.
Keep going.

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.

I've always said our ambition with @WHOOP is to create something that's either cool or invisible. Today, we're taking that philosophy to the next level with the launch of LAYER 2, our latest collection with Samuel Ross. Available now via link below.

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.

The pulse in the stands tells a similar story.

During last season’s championships, fans tuned in to basketball’s biggest stage felt it most, with a Strain of 5.3 and a peak heart rate of 146 bpm. The hardest sport to play might also be the hardest to watch.
