Correct Body Posture for Working with PC

Prolonged sitting in one position is not natural for the human body. However, in today's digital world, more people are working with computers and spending long hours in office environments. This has led to an increase in health problems, which may start as minor discomfort but can develop into serious conditions, such as back pain, hand pain, tennis elbow, carpal tunnel syndrome, tendon and muscle inflammation, and other repetitive strain injuries (RSI). The science of optimizing working conditions is called ergonomics. Its aim is to design work environments that promote good health, safety, and optimal work performance. Ideally, a workplace should be tailored to the specific physical characteristics of each individual. Body posture at work is especially important. One useful guideline is the "right angle rule." Legs should be bent at the knees at a right angle, with the feet flat on the floor. Maintaining an upright posture ensures a right angle between the torso and thighs. The forearms should also form a right angle with the upper arms. Muscle tension is often caused by raised or slouched shoulders, so the elbows should rest slightly above the keyboard. Proper desk height is also critical for comfort. A quality chair is the foundation of healthy sitting. Factors such as height adjustment, mobility, and structural firmness all contribute to workplace comfort. Supporting the lower back, particularly at the sacrum, helps maintain an upright posture without straining the muscles around the spine. It is important to regularly stretch and change positions throughout the workday. Taking breaks to relax, do a few exercises, or walk can also help prevent strain and promote better health.
