Scientists offer some surprising answers.

I write about sleep.
Don’t look at your phone before bed if you want a decent night’s sleep, we’ve been told. In fact, put it in another room! The blue light from screens will make it harder for you to conk out and leave you feeling less rested tomorrow, research says. Right?
Actually, no. The link between blue light and sleep is murkier than originally thought, scientists now say. In some cases, screen use can even help you sleep. This doesn’t mean you should turn on every device in your bedroom before you hit the sack. But there’s already enough anxiety about how to sleep well; maybe don’t stress about this.
