I am a CS student, so my career requires sitting for long periods of time (8~9) hours infront of a laptop daily. I've been hearing for quite a long time that computers are harmful for health. I'm really concerned with my health but I'm comfortable with this lifestyle.
Is there any proof that computers are harmful and/or they cause serious health problems ? Are there any health problems that are specific to some types of computers that no more exist with modern hardware ?
Clarification
I'm interested in physical and cognitive/brain problems alike.
Cognitive problems are more important in this case.
Examples of physical problems likely for long-time computer users:
- Back bending.
- Eye-sight damage.
- Less energy consumption problems (because of sitting all day) like sleeping problems.
Examples of cognitive problems likely for long-term for computer users:
- Loss of attention.
- Cognitive effects of learning computer programming
