I heard that staying before your monitor too long is bad for your health. So I bought this timer and keep it with me all the time when doing homework, coding, writing or just playing games.

I set the alarm every 35 minutes, so whenever it rings, I would stop doing whatever I do with my laptop and turn it to sleep. For the next 15 minutes I'll take some rest and do some light excercises.

And I repeat that till I'm done with whatever shit I am doing.

The question is... Is it safe to repeatedly put your laptop to sleep multiple times in a row like that?
