Looking at a monitor all day is not healthy no matter which brand it is. You’ll have dry eyes eventually and sleep problems too. Looking into the bright light all the time fries your brain and it forgets to put itself to sleep.
If you are doing lots of trades in a day, you better write your own trading algo and let it do the job. Otherwise you’ll lose what’s left of your current health soon.
From time to time, you need to get away from your monitor. Take a break if needed. Focusing all day, all night long on bright screen is indeed not healthy. Find a way how to take small breaks, it can surely help.
