    Healthy Computing Guide
Introduction
This guide is designed to help you be more comfortable and productive
while using your computer. It may also help you reduce your risk of
experiencing painful and disabling injuries or disorders described in the
Health Warning earlier in this manual.
It only takes a moment to read, but the benefits can be lasting.
For information about arranging your workstation and developing habits that may
help to reduce your risk of experiencing an MSD, read this “Healthy Computing
Guide.” Because there are a variety of factors that may contribute to MSDs, this guide
cannot provide everything you need to know to prevent an MSD or reduce your risk
of experiencing one. For some people, following the suggestions may reduce their
risk of experiencing an MSD. For others, it may not. However, many people experience
greater comfort and productivity when following these suggestions. Keep in mind
that this guide is not a substitute for the advice of a qualified health professional or 
an employer health policy or program. If you have questions about how your own
lifestyle, activities, or medical or physical condition may be related to MSDs, see a
qualified health professional.
Position Yourself
Whether you are working or playing, it is important to avoid awkward postures and
position your body comfortably. Not only can this improve your overall productivity,
it may help you avoid musculoskeletal disorders (MSDs). Keep in mind that changing
your posture during extended tasks may also help you avoid discomfort and fatigue.
When working or playing at the computer, adapt your surroundings and arrange your
computing equipment to promote a comfortable and relaxed body posture. Setting
up your workstation to avoid discomfort depends on your unique body size and work
environment. However, the following suggestions may help to provide you with a
more comfortable environment.
To support your back, try the following:
●  Use a chair that supports your lower back 
(see detail
1
).
●  Adjust your work surface and chair height to 
assume a comfortable and natural body posture
(see detail
2
).
To promote comfortable leg postures,  
try the following:
●  Clear away items from beneath your desk to allow 
comfortable leg positioning and movement.
●  Use a footrest if your feet do not rest comfortably on the floor.
