- What is Ergonomics? What is Workplace Ergonomics? Why do I need to know about Ergonomics?
Ergonomics is defined as the science of understanding the interactions of men in sync with their environment (all the objects around at work, at home, etc.). Workplace Ergonomics is the science of fitting a job to an employee to help prevent any form of Musculoskeletal Diseases (MSDs) which are likely to happen to be a part of that workplace. This connects us to ‘Ergonomics’ and that everyone needs to know Ergonomics to stay fit in their respective workplaces. Fitter employee health means better productivity, improved work output, and decreased long-term detrimental effects.
- What happens physiologically when Ergonomics is not taken into consideration?
When the normal screen time is increased pursuing postures other than recommended, a condition called Asthenopia or Tiredness of eye muscles may occur along with certain others like Redness and Dry eye syndrome. Not just eyes, the brain also starts to show the signs of central fatigue due to extended screen and cell phone hours in the form of reduced ability to produce movement. Last, but not least the physical form of fatigue manifests itself in the form of lower back pain, neck pain, giddiness, or numbness in the fingers.
- What can be done to keep MSDs at bay?
Physical activity, certain exercises, muscle stretches, and small breaks. There is always a correct posture and way to carry out a certain activity. Follow that.
- Do I always have to sit on the table and chair?
The table chair is important. I do not mind small bouts of pillow and bed working but your maximum time should be on a table and chair. This helps avoid repetitive strain injury by reducing pressure on small joints and muscles of the hand.
- How about on the floor with a cushion against back?
Not recommended as more pressure on the cervical spine (neck) due to forward-leaning is indicated with the posture.
- What if I don’t have a table chair at home?
The dining table would do, chair height can be adjusted by placing hard cushions under your buttocks.
- What posture is recommended then?
Make sure you adjust its height as per yours; the key is neck neutral, wrist neutral, and eyes at around 15 degrees above the horizontal. There should be at least an arms distance between the screen and you.
Back straight and totally in contact with your chair support. Knees and hip in 90 degrees with your torso. Feet flat on the ground, use a footstool if falling short. A format with either mouse or keyboard is helpful in reducing waste movements and undue strain on body tissue. The best pointer is to insert a small break every two hours.
