Every function of the human body can be seen as a rhythmical balance between energy consumption and energy replacement, or between work and rest. This dual process is an integral part of the operation of muscles, of the heart,
and of the organism as a whole. Rest pauses are indispensable for farm workers as they do more grueling job and repetitive motions during agricultural activities. Farm workers are exposed bending, squatting, stooping or standing posture for long periods during their work. Lifting or carrying heavy loads are also part of agricultural activities. These awkward postures and heavy work cause musculoskeletal disorders. Appropriate rest periods should be allowed to the farm workers to prevent musculoskeletal injuries.
