Getting an adequate amount of sleep is vital for your mental and physical health, as well as your happiness. But actually getting a solid night’s rest isn’t as easy as it sounds. Daily stresses and a wandering mind can make falling to sleep extremely difficult.

In the United States alone, scientists estimate roughly 60 million Americans struggle with insomnia. As technology has advanced, our ability to “turn off” at the end of a day has become more difficult. Staring at computer and phone screens all day tires our eyes but wakes our brains up, and although it is tempting to look at our phones right before bed, we would do well without it. Our phones, computers and energy-efficient light bulbs all emit blue light, which is harmful to your health. Our circadian rhythm is what makes us (usually) want to sleep during the night and be awake during the day. Most people run on a close to 24 hour cycle. Unfortunately, blue light significantly impacts our circadian rhythms, making sleep much more difficult.

Add in the hustle and bustle all around us, bright lights, and general body discomfort, and it’s amazing we can sleep at all, let alone get an actual night of peace and dreams.

There are natural ways to help yourself sleep better. Limiting your caffeine intake, stretching before you go to bed, and even eating a light dinner can all help you catch more Zzzs. But sometimes, even though you try hard to follow all of the steps to get a restful night of sleep, it just seems impossible.

Learning your sleep habits can make all the difference. We know, you’re thinking, “who has time to track their sleep?” Well, the one great thing about technology is it allows us to do so much more than keep us up at night.

Thanks to the beauty of modern technology, there are lots of sleep systems out on the market that can help you understand how you sleep and help train you to start sleeping better. To give you an idea of the variety of items that exist, here are 20 gadgets that will help you catch more Zzzs as early as tonight.
