We all probably have an idea about the many problems, physical and psychological, that can arise out of extended and uninterrupted periods spent working on the computer. It can also affect your social life and interpersonal relationships.
And now there is some evidence to show that working on the computer long hours may also be a cause for disruption of your sleep [good night sleep].
