2 . We know it can be hard to put your phone to bed before you sleep. However, if you’re trying to improve your sleep, you really should ditch your phone at least an hour before bedtime. Luckily, our experts can help.

Scientific evidence suggests that the blue light emitted from your phone, tablet, computer, and TV suppresses (抑制) your body’s production of melatonin, a hormone (荷尔蒙) that plays an important role in your sleep cycle. Melatonin release in the evening helps you relax before bedtime. A 2013 study that analyzed technology use and sleep patterns with data from a National Sleep Foundation poll found that using devices like phones was tied to more sleep disruption than electronics that aren’t interactive.

Many of us use the excuse that our mobile devices serve as our wake-up calls, or keep them nearby to use meditation apps. If you want to use your phone as an alarm, consider setting it a couple of hours before you turn in for the night, and then setting the phone itself to bedtime mode for the rest of the evening.

Here’s another groundbreaking idea: You could get a real alarm clock. After reviewing them at Reviewed, we recommend the Sharp Dream Caster. Not only is it easy to set a wake-up time, the clock includes white noises and rain noises to help you sleep, plus a number of volume settings to pick what works best for you.

But an alarm clock won’t help you avoid doom-scrolling through social media. Take things a step further by avoiding using electronic devices. You can try reading a book (one made of paper), taking a bath or drinking a cup of chamomile tea.

Finally, if you want to keep up your meditation practice screen-free, consider the Morphée. It looks like a little music box and comes with a variety of breathing exercises and soundscapes to help you get to sleep.
