Scientifically speaking, sleep can make you look better. That’s because while you sleep, your body undergoes several biological processes that help restore its appearance and functioning.1

Think of your body like an office or school. During the day, when you work, you make a mess and accumulate trash. At night the cleanup crew comes through and puts everything back into place. If you worked around the clock, there wouldn’t be time to tidy and the general state of cleanliness would deteriorate. In the same way, your body goes into repair mode when you sleep, replacing older cells with new ones so you wake up with brighter, healthier skin and fewer dark circles.1

When you get a good night’s sleep, others notice too. In one study, researchers asked participants (between the ages of 18 and 31) to sit for two photographs: one after getting a full night’s sleep and another after being somewhat sleep deprived.2 The photos were then shared with a group of random observers who were asked to rate the portraits based on healthiness and attractiveness. Overall, the photos of well-rested participants were rated more attractive.2

Sounds great, right? Just sleep more to look better. But we know it’s not that simple. Whether it’s congestion, a bad bed partner, or work stress—with each night comes new obstacles to getting good sleep. That’s why it’s important to establish a routine to help you sleep better.
