If you find you’re waking up exhausted or having lots of sleepless nights, you can partly blame the many hours you spend staring at screens of various sizes. A number of studies that have recently emerged suggest that the closer to bedtime you use your phone or tablet, the harder it is to get a good night’s sleep. Our bodies operate on circadian rhythms that play a role in how alert we feel throughout the day. And since our brains respond to light and darkness, that blue light emanating from your phone at 2 a.m. – when you are generally meant to be having the deepest sleep – messes with your internal clock and makes your brain tell your body you should be awake. This infographic by Boll & Branch offers more information and ideas on getting restful sleep in an age of 24/7 connectedness.
