These gadgets and apps can help you find the best way to wind down, sleep deeply, and wake up feeling recharged.

1. Wake Up Light Alarm Clock

There’s nothing more disorienting than being awakened from a deep sleep. That’s where the Wake Up Light Alarm Clock comes in. This clock gradually lights up in the morning, simulating the sun to wake you in the most natural way possible. It also offers five nature sounds, so you’ll never hear the startling BZZZ of an alarm clock (or your phone) again.

2. Marpac Dohm-DS White Noise Machine

The Marpac Dohm – DS White Noise Machine offers calming sounds that will help you drown out the excess noise in your surroundings. Simply choose your preferred volume and place the machine by your door to block out external sounds. Users have found it to be so effective that it’s the Official Sound Conditioner of the National Sleep Foundation.

3. F.lux

Scientists originally designed computers to look like the sun, giving off bright lights that easily grab our attention. But at nighttime, the blue light emitted by our screens has been shown to harm our ability to fall and stay asleep. So F.lux adapts the color of your screen based on the time of day. It produces warm-colored lights at night and cold-colored lights during the day. In situations when you simply must use your technology close to bedtime, F.lux is there to protect your sleep one shade at a time.

4. Pzizz

Rooted in psychoacoustics, the branch of science concerned with how sound influences how we feel, Pzizz offers music, sound effects, and beats to enhance your sleep. This app generates over 100 million different sounds to calm the mind and help you fall asleep faster. Listen 10 to 30 minutes before bed to enter your bedroom feeling relaxed and ready to rest.

5. Calm

Calm gets you into the perfect mindset for a great sleep. As a top app for mindfulness and meditation on iTunes, Calm helps you destress before bed with guided meditations, breathing programs, and what the makers call Sleep Stories. It’s everything you need to feel centered before bedtime.
