Alex works at his computer for several hours a day. He is careful to sit up straight at the computer with his feet on the floor and to keep his muscles
relaxed, and stays off his computer after 6 p.m. For what kind of computer-related health problems is Alex still at risk?

A. musculoskeletal problems
B. vision problems
C. sleep problems
D. headaches

Respuesta :

B. Vision problems likely. Getting off a computer at 6 pm prevents sleep issues so it is not that.

Answer:

D. Headaches

Explanation:

You already addressed that he takes care of his musculoskeletal health by sitting the right way and that he has a 6 pm curfew for screen time, so no sleep problems either. Vision problems are likely, but personally I get headaches more often. I mean, my visions been bad for years and it takes a while for screen-time to have a huge effect on that.
