What is Computer Science? Can someone please explain to me?

Can someone please explain the nauseating feeling I get after computer use.?

• I've noticed that whenever I spend a lot of time on my computer I start to feel sick and nauseous, usually it goes away after a while if I stay off the computer or go to sleep. I am wondering what causes these feelings, is it the brightness, the wifi, the backlight of the screen, is it even because of the computer? Being one who uses the computer often and usually for long periods of time, I would like to know if there is anything I could do to avoid this or minimize it so I can do what I need to do and not feel sick afterwards? Also, if you have any god info about this type of thing (NOT about why you shouldn't sleep with your cellphone next to you) then please do share.

• Answer:

  Sometimes the screen 'refresh rate' makes eye strain more prominent. See if yours can be changed. Also, take 5 minute walks every 45-60 minutes during marathon sessions, stretching and loosening up joints, get the heart pumping helps also.
