While most people believe it is relaxing
While most people believe it is relaxing, sitting is actually hard on the back because it transfers the full weight of the upper body onto the buttocks and thighs. Sitting, especially for long periods of time, can also cause increased pressure on the intervertebral discs- the springy, shock-absorbing parts of the spine and also cause health problems such as back and neck pain, eyes strain, abdominal pain, leg pain, and repetitive motion disorders.
It’s also hard on the lower extremities since gravity pools blood in the legs and feet and creates a sluggish return of blood to the heart. Well-constructed and proper use of ergonomic chair helps in reducing fatigue and discomfort, increase blood flow, reduce the risk of injury, and increase productivity. (Rodts, DNP, 2017)
