Arthritis problems affecting factory and production-line workers can show up in almost any joint in the body and are caused by long spells without a break, vibrating equipment, repetitive overuse of muscles, poor posture, or a badly-organised work area. Repetitivestraininjury.org.uk advises regular breaks, particularly if you are feeling tired, learning muscle-relaxing techniques such as diaphragmatic breathing, and trying to keep in good shape by eating and drinking healthily. If you have time, yoga may be a beneficial extracurricular activity to add to your daily routine because it will allow you to stretch the entire body and also strengthen your muscles in order to prevent the pain and stiffness that can develop while on the factory line.
