With a finite number of discretionary hours in a day, essential activities could be DISPLACED by excessive use of Wireless Mobile Devices (WMDs). High screentime has been associated with obesity, sleep disorders, and behavioral health issues.
This is how it might play out.

Screens have been transplanted from the walls of the living rooms into the palms of children and adults.
With every hour per day increase in screentime, the chances of weight gain increase too.

As the wireless mobile devices (WMDs) have become smaller, ‘smarter’, portable and affordable, more users are able to access technology and ‘watch TV’ on the small screens, in the bedrooms.
As a result, sleep gets compromised.

High screen time and insufficient physical activity interact to increase
depressive and anxiety symptoms and life dissatisfaction.
