Researchers found that people who sleep two to four hours a night are 73% more likely to be obese than those who get seven to nine hours. Those who get five or more hours of sleep a night are 50% more likely to be obese than normal sleepers. Those who sleep six hours are 23% more likely to be obese.
Scientists have found that sleep deprivation increases levels of a hunger hormone and decreases levels of a hormone that makes you feel full. The effects may lead to overeating and weight gain.

It could explain why so many Americans who are chronically sleep-deprived also are overweight. And it could be part of the reason sleepy college students, new parents and shift workers pack on pounds.

Researchers say getting enough shut-eye might be a critical component of weight control. And nutritionists one day might routinely advise dieters to “sleep it off” as well as to cut calories and increase exercise.

Studies have shown that migraine sufferers are particularly affected by blue wavelength light, Freitag says, and that happens to be one of the common background colors for computer screens.

So a simple solution is to change the background color of the screen or to wear glasses that block out blue light, Freitag says.
Too many hours reading text on the computer can lead to eye strain, says Dr. Steven Galetta, professor of neurology at the University of Pennsylvania Medical Center in Philadelphia. This problem worsens with age as it becomes harder and harder to focus on close objects.

One way to counteract this problem is to give your eyes a break every 15 to 20 minutes by looking away from the computer and at something in the distance

You can also do eye-strengthening exercises.

“We call them pencil push exercises,” Galetta adds. “Hold the pencil in front of your face and slowly bring it towards your nose as you focus on the eraser. Move the pencil back and forth for approximately five minutes. It’s like training any muscle that you want to make stronger.”

The way you sit at your computer can also make a difference. If the monitor is set too high, it may lead to neck strain, which in turn may lead to head pain.

“If you’re looking up at your computer monitor, your head may be extended backwards and that can put a lot of stress on the big muscles of the neck,” Galetta says. “You want to make sure that (the center of) your computer monitor is a little lower than your eyes.”
