horizontal (2), with your wrists in a neutral, comfortable position (3) while using the keyboard,
touchpad, or external mouse. Let your upper arm s hang na tu ra l ly at yo ur si des . Have breaks during
sessions with your computer. Excessive use of th e computer may strain muscles or tendons.
Furniture and posture – Sit in a chair with good back support. Ad just the level of the chair so your feet
are flat on the floor. A footrest may make you more comfortable. Sit in a relaxed, upright posture and
avoid slouching forward or leaning far backwards.
