Wrist rest

[2] The main benefit of using a wrist rest is increased comfort, especially for those using keyboards over long periods.

[1][4] Usage of a wrist rest can alleviate tension can take away pressure from the neck, shoulders and arms.

[1] Prolonged contact between the wrists and the rest may cause carpal tunnel syndrome or tenosynovitis.

[1] To mitigate potential problems, the Occupational Safety and Health Administration (OSHA) recommends the hands to be elevated above the rest while typing.

[1] A 2004 study published in Elsevier described the literature on the efficacy of wrist rests as "limited, inconclusive, and contradictory".

The wrist can be strained by the increased angle when typing without a rest.
