1 . 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.

6 . One evening, I was on the air as usual, broadcasting my radio show, taking requests, chatting with listeners, and looking through e-mails. I stopped on an e-mail begging for help. It was from a woman named Winifred at a refugee (难民) camp at Buduburam in Ghana. She needed money to care for three small children. I was about to hit delete (删除) — it had to be a cheat — but something stopped me. I had a chance to go there for a report the next week.

I had a picture in my head of what I thought I’d see. But the reality of the camp was nothing that I could have ever prepared myself for. I found Winifred and her family among more than 42,000 others, surviving on one meal a day-sometimes less, with no clean water, no toilets. The suffering was extreme. I helped Winifred’s family.

But there was so much more need. Where could I possibly start to make a difference?

One day not long after I’d gotten back from Ghana, I went into my kitchen to get a snack. A small sound stopped me. Plink. The tap was dripping (滴落) ever so slightly. I couldn’t take my eyes off that tiny, shining drop. Water. It seemed like such a simple, basic thing for me. But for the people at Buduburam, it was a matter of life or death.

I turned off the tap, tight. Suddenly I knew what I had to do. I created a project called Point Hope, to bring water to the people at Buduburam. Today there are 12 pumping stations at the camp.

I’ve returned to Ghana many times to check in on the water projects, and meet with people. They call me mum. They remind me of Ghana-where so much remains to be done. I strongly believe that with enough devotion and faith, we can bring more hope. You! Me! All of us!
