You use a wrist cushion primarily for palm support while resting your hands, not while actively typing.
Using a wrist cushion effectively involves understanding its purpose and incorporating it correctly into your workstation setup. Here's a breakdown:
Proper Usage of a Wrist Cushion
-
Primary Purpose: A wrist cushion (more accurately, a palm rest) is designed to provide support and reduce pressure on the palms of your hands during brief pauses in typing, not constant support during active typing. It's intended to be used during breaks or moments when your hands are idle.
-
Hand Position: While typing, your hands should move freely above the cushion. The heel of your hand or your palm should make contact with the cushion only during rest. Your wrists should not rest on the cushion while typing.
-
Ergonomic Integration: A wrist cushion should be part of a larger ergonomically sound computer setup. This includes:
- Chair Height: Adjust your chair so your feet are flat on the floor or supported by a footrest.
- Keyboard Height: The keyboard should be positioned so your elbows are bent at a 90-degree angle and your wrists are straight.
- Monitor Position: The top of your monitor screen should be at or slightly below eye level.
- Posture: Maintain good posture with your shoulders relaxed.
-
Incorrect Usage: Avoid resting your wrists on the cushion while typing. This can restrict movement and increase the risk of carpal tunnel syndrome and other repetitive strain injuries.
Why Improper Use Can Be Harmful
Resting your wrists on a cushion while typing can:
- Compress the median nerve: This nerve runs through the carpal tunnel in your wrist. Compression can lead to carpal tunnel syndrome.
- Restrict blood flow: Constant pressure on your wrists can hinder circulation.
- Cause discomfort and pain: Over time, improper use can lead to pain and stiffness in your wrists, hands, and arms.
Key Takeaways
- Wrist cushions are for resting the heel of your hand or palm, not your wrist, during breaks in typing.
- Ensure your hands float freely above the cushion while typing.
- Incorporate the cushion into a complete ergonomic workstation setup.
