Sleep science fact of the day...

If your breathing at night isn’t optimal, your sleep quality drops. And something fascinating happens in the brain the next day… You start craving fatty, high-calorie foods.

This isn’t a willpower problem. It’s biology.

When you don’t sleep well, your body shifts into what I call a “survival mode.”

From an evolutionary biology perspective, our ancestors who were sleep deprived were often in danger, stressed, or in unstable environments. The brain responded by pushing them to seek energy-dense foods quickly so they could survive the next day.

Modern research shows the same pattern.

Sleep restriction increases appetite signals like ghrelin, the hormone that stimulates hunger. Even a single night of sleep deprivation can increase ghrelin levels and hunger feelings the next day.

In controlled laboratory studies, sleep-restricted participants consumed 300–500 extra calories per day compared with normal sleep.

Another study found people stayed awake longer only burned about 17 extra calories per hour, yet they compensated by eating 300+ extra calories in snacks, especially high-calorie foods.

In other words: Poor sleep → more cravings → more snacking → weight gain.

And here’s the part most people miss. One of the biggest hidden drivers of poor sleep quality is breathing health during sleep. Issues like sleep apnea or upper airway resistance can fragment sleep all night long without you even realizing it.

This is why it can make sense to measure your breathing health directly.

Today you can do this using FDA-cleared at-home sleep tests available through CPAP.com.

The process is simple:

• Sleep with the device for 1–3 nights
• Data is recorded while you sleep
• A qualified medical doctor reads the report

This can reveal whether breathing disruptions are quietly degrading your sleep quality. Fix the breathing. Improve the sleep. And sometimes the cravings take care of themselves.

It might be hard to believe, but the SleepSpace algorithm on Apple Watch is more accurate than Oura and Apple Watch for detecting sleep stages. And we have the data to prove it!

The reason for this is that SleepSpace activates high data resolution mode of the Apple Watch. It drains the battery a bit more, but it produces more granular sleep stage data as shown in the above image. Additionally the algorithm was built from thousands of nights of polysomnography data.

So if you are interested in improving sleep quality, use the SleepSpace app on Apple Watch!

Do you know what the most important variable for sleep health is?

The answer is ensuring the you are not sleep deprived. It is also important to understand that better sleep quality and a stronger circadian rhythm are key factors that can reduce the likelihood of being sleep deprived.

Sleep deprivation has been linked to:
❌ Daytime fatigue
❌ Increased likelihood of every chronic disease (cancer, heart disease, etc)
❌ Inability to to make clear decisions
❌ Brain cannot clear harmful toxins (metabolic waste and beta amyloid)
❌ Even a worse sense of humor!

This is why we just release a new sleep debt feature in SleepSpace!

SleepSpace now calculate sleep debt more closely and displays your daily energy levels using something called the 3-Process Model of Sleep.

Did you know that playing brown noise while performing a cognitive task was recently shown to help people with ADHD? A research group in Western Norway University showed that brown noise in particular, improved performance on memory and language tasks. (see: https://www.washingtonpost.com/wellness/2022/11/14/brown-noise-adhd-focus/ )

That's why we made brown, pink, white, and green noise more accessible from within the SleepSpace app.
