Science of Sleep: WHOOP & Why You Should Spend More Time in Bed

Sleep. All of us (hopefully) spend a good chunk of each day doing it, but are we doing it right?

Well, according to Emily Breslow, Lead Quantitative Physiologist / Analytics Manager at WHOOP, the answer is a resounding "no." In fact, most people only spend 80 to 94% of the time that they are in bed asleep. Whether it’s due to genetics, age, stress or general restlessness, when we think we’re resting many of us are actually missing out on much needed sleep. Say you typically go to bed at 10 pm and wake up at 6 am, to ensure 8 hours of sleep, the optimum amount, you should probably hit the sack 45 minutes earlier. Are your eyelids getting heavy yet?

WHOOP can help.


The term “wearable,” tends to evoke the process of counting steps and calories burned during exercise. While these two measurements are easily understood, they’re generally incomplete indicators of fitness, as they don’t account for so many other factors that contribute to your daily performance. WHOOP, on the other hand, customizes to your baseline to measure your Strain, Sleep, and Recovery through 24/7 performance monitoring.  

“The thing most people don’t realize is that you're not getting stronger in the gym—you're getting stronger while you sleep,” says Breslow. By continuously measuring the body’s output,  WHOOP provides actionable recommendations to enhance athletic performance, reduce risk for injury, avoid overtraining, and let you know exactly how many minutes of sleep you need each night. If you’re looking to become a better athlete, it’s not about doing an extra set at the squat rack, it’s all about prioritizing sleep!


Outside of it being one of our favorite pastimes, sleep has innumerable health benefits. According to WHOOP, here are some key positives to getting your full regimen of shut-eye.

         1. Say "bye" to bags.

Some mornings you might notice dark, sagging bags beneath your eyes. That’s because you’re sleep deprived. In addition to bags, lack of sleep can make it difficult for your skin to fight off acne.

         2. Full, lustrous hair? Unbreakable nails? Sign me up!

People who are chronically sleep deprived tend to have more brittle nails and thinner hair than those who habitually manage to squeeze in 8 hours. According to Emily, supermodels can sleep up to 12 hours each night because of how good it can be for your skin

         3. Improve your memory.

About a quarter of the time that we are asleep is spent in REM sleep: the mentally restorative stage when we consolidate experiences from the day into our long-term memory. If you don't get enough REM sleep then you’re going to have a foggy brain the next day. And nobody likes a foggy brain.

         4. Recover faster, get bigger, repeat.

Slow Wave sleep, which tends to happen earlier in the night, is the physically restorative part of sleep; during this stage, growth hormones are released. So if you just finished a grueling workout, in order to maximize its impact, this sleep stage is integral. Any torn muscle tissue gets repaired as much as possible during this stage of sleep. WHOOP gives your Sleep Cycle breakdown every morning, so you know exactly how much Slow Wave Sleep (SWS) you accomplished.

         5. Cat-like reflexes!

Remember REM sleep, the type that improves memory? It’s also responsible for enhancing focus and reaction time. Whether you’re cruising through spreadsheets at the office or training for a race, getting the right kind of sleep has the ability to improve performance.
