Yahoo News: There are a number of behavioral changes that people can use to improve their sleep.
Cut the light. One of the best things to do is trick our brains with light. Sunlight doesn’t just make us feel healthier, but it can also indicate that it’s time for our bodies to wake up. If you are trying to go to sleep when it’s still light out, that can make it hard to reset your sleep schedule.
Blackout curtains for the win. Blackout curtains may be a good purchase, especially if you’re working during a night shift. Other lights also should be dimmed.
No tech before bed. And yes, that also includes the light from a smartphone or a video game. Technology often uses blue light, which can trick your brain into reactivating instead of shutting down.
