•
num"ness

Seek help even if symptoms occur when you are not working at your computer. aptop computers can present particular pro"lems due to small screens, key"oards and in"uilt pointing devices :e.g. a small porta"le mouse or touchpadF. +rolonged use of laptops should "e avoided. f using a laptop as a main computer :i.e. use as a normal desktop computer in addition to use as a porta"leF, it is advisa"le to use the laptop with a docking station. This allows an ordinary mouse, key"oard and monitor to "e used with the laptop. The main risks associated with using computers include' •
0usculoskeletal pro"lems

3ye strain and a greater awareness of e1isting eye pro"lems *ashes and other skin complaints have also "een reported, although it is thought these are caused "y the dry atmosphere and static electricity associated with display units rather than "y the display units themselves.
