Health.com: What to Do If You Can't Fall Asleep

One Hour Before Bedtime

Dim your screens. Watching TV or tooling around online may help you decompress, but most screens emit more blue light than lamps do, and that—plus any exciting or disturbing stuff you see—will keep your brain going.

So if you can't give up your late-night screen time, at least turn down the brightness on your TV, tablet, or computer. You can also install a free program called f.lux on your laptop to automatically reduce the blue light it emits at night.
