Screen time

Phones, tablets, computers and televisions are useful, but hours in front of a screen cost the body. Staring at a screen we blink less, so the eyes get dry and tired; bending the head over a phone strains the neck and back; screen light late in the evening tells the brain it is still day and delays sleep; and every hour sitting at a screen is an hour the body isn't moving. Resting the eyes on something far away, sitting straight with the screen at eye level, getting up often and putting screens away before bed all help.
