Why Your Desk Job Might Be Hurting Your Health; Doctor Explains

In today’s digital era, millions of professionals spend the majority of their workday seated at a desk, often under the illusion that a sedentary job is easier on the body than physically demanding labour. Researchers analysed 13 studies of sitting time and activity levels among more than 1 million people. They found that individuals who sat for more than eight hours a day without physical activity had a risk of dying sooner compared to those posed by obesity and smoking. However, 60 to 75 minutes of moderate aerobic physical activity each day offsets the effects of excessive sitting. Other studies found that for most active people, sitting time has little effect on their risk of death.

From chronic back pain to digital eye strain, the risks associated with desk jobs are more widespread and serious than many realise. Even more concerning is the fact that these health issues often develop gradually, making them easier to ignore until they become chronic or debilitating. Sitting for extended periods without regular movement can increase the risk of conditions like obesity, diabetes, cardiovascular disease, and even early mortality, comparable to the dangers of smoking. In conversation with The Daily Jagran, Dr.Shubhada Karande- Occupational Therapist and Ergonomic Consultant, Interio, shares the hidden hazards of sedentary work and offers practical, science-backed tips to stay healthy, energised and pain-free at your desk.

Back Pain: More Than Just A Nuisance

Why it happens: Poor posture and inadequate lumbar support put strain on spinal discs and back muscles, especially in the lower back.

Preventive measure: Use a chair with proper lumbar support, sit with your feet flat on the floor, and avoid slouching. Keep your knees at a 90-degree angle and your back upright. Shift positions frequently throughout the day.

Muscle Imbalance And Weak Core

Why it happens: Long sitting hours weaken core muscles and glutes while overworking hip flexors and the lower back.

Preventive measure: Include core-strengthening exercises such as planks or seated pelvic tilts in your routine. Stand and stretch at regular intervals to keep hip and back muscles engaged.

Repetitive Strain Injuries (RSIs)

Why it happens: Continuous use of keyboard and mouse without breaks can lead to strain in the wrists, shoulders, and elbows.

Preventive measure: Maintain a neutral wrist position while typing. Keep your keyboard and mouse close and use an ergonomic keyboard or wrist rest. Take micro-breaks every 30–40 minutes to stretch hands and arms.

Digital Eye Strain And Fatigue

Why it happens: Prolonged screen time may lead to dry eyes, blurry vision, and headaches.

Preventive measure: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. Adjust your screen to eye level and reduce glare using filters or matte screens.

Mental Health Impact

Why it happens: Lack of physical activity and constant digital engagement can contribute to stress, burnout, and social disconnection.

Preventive measure: Incorporate short walking breaks, breathe deeply during transitions between tasks, and prioritise work-life boundaries. Include regular physical activity in your daily routine to support mental well-being.

Poor Ergonomics Compounds The Problem

Why it happens: Inadequate chair support, improper screen or desk height, and awkward posture add stress to joints and spine.

Preventive measure: Set up your workstation with your monitor at eye level and an arm’s length away. Adjust your chair height so your Thighs are parallel to the floor and your feet rest flat. If needed, use footrests or monitor risers.

Movement Is Non-Negotiable

Why it happens: Even the best setup can't compensate for hours of immobility.

Preventive measure: Set reminders to stand up or stretch every 30 minutes. Walk during phone calls or incorporate walking meetings. Try shoulder rolls, neck stretches, and spine twists at your desk to stay flexible.

Prevention Starts With Simple Changes

Why it matters: Small habits adopted early can prevent long-term musculoskeletal damage.

Preventive measure: Practice good posture, adjust your chair and monitor placement, and use ergonomic accessories. Stay hydrated and include nutritious foods to support muscle and joint health.

Muscular stiffness at work is a clear sign of how prolonged sitting and poor posture affect our health. From back pain to burnout, the risks are real but also preventable. Simple changes like better posture, regular movement, and an ergonomic setup can make a big difference. Desk jobs are here to stay, but discomfort and long-term damage don’t have to be. A few mindful habits each day can help protect your health and improve your quality of life.
