There can’t be such a thing as a sleep hack, right? At least, that’s what I thought for years. But if there’s anything we should hack, it’s our sleep.

On average, you sleep 7 hours and 50 minutes per night. Considering that life expectancy for countries in the Western world is about 80 years—you’ll spend 26.6 years of your life asleep.

That’s almost 1/3 of your time on this planet. And yet, we feel tired so often. Just look at the person sitting next to you at the office, on the couch, or at Starbucks.
