Top 10 Ergonomic Risks at Computer Workstations and How to Spot Them

Sitting at a computer for hours might seem safe—after all, you’re not climbing ladders or handling hazardous chemicals. But believe it or not, ergonomic risks at your computer workstation can lead to serious, long-term workplace hazards if not managed properly. These risks can silently affect your body, productivity, and overall well-being.

Whether you’re working from a bustling office in Lahore or a cozy corner in your home, understanding how your workstation setup impacts your health is crucial. In fact, organizations that prioritize ergonomics often see a drop in employee injuries, improved morale, and better performance.

The Importance of Ergonomics in Workplace Safety

Workplace safety isn't limited to construction sites or factories. Sitting for extended periods, poor posture, repetitive motion, and improperly placed equipment can all pose hidden dangers. That's where ergonomics steps in—designing workspaces that suit human capabilities and limitations.

To create a safer work environment, many safety professionals pursue the NEBOSH course in Pakistan. This course equips them with the knowledge to identify and control workplace hazards, including ergonomic ones. It's a step forward in building safer office environments.

Let’s explore the top 10 ergonomic risks you may face at your computer workstation, how to spot them early, and simple tips to correct them.

1. Poor Posture

Have you ever found yourself slouching, leaning forward, or sitting with your legs twisted under your chair? That’s poor posture—and it’s one of the most common ergonomic risks. Over time, it can lead to neck strain, back pain, and even spinal issues.

How to Spot It:

You often feel sore in your neck, shoulders, or lower back.
You find yourself leaning into your screen to read clearly.

What You Can Do:

Sit with your feet flat on the floor.
Keep your back supported with a good office chair.
Your screen should be at eye level to prevent neck bending.

Pro Tip: Imagine a string pulling the top of your head upward. That’s the posture you want!

2. Incorrect Monitor Height and Distance

If your monitor is too high, too low, or too far, your body compensates. That can cause eye strain, headaches, and even chronic neck pain.

How to Spot It:

You tilt your head to see the screen better.
You lean forward or squint.

What You Can Do:

Your eyes should be level with the top third of the screen.
Keep your monitor about an arm’s length away.

A friend once told me she solved her chronic migraines just by adjusting her monitor’s height. Simple change, big impact!

3. Inadequate Chair Support

Not all chairs are created equal. Sitting in a chair that lacks lumbar support or is the wrong height can make your back suffer.

How to Spot It:

Your lower back feels sore.
You slide forward or constantly adjust your sitting position.

What You Can Do:

Invest in an ergonomic chair with adjustable lumbar support.
Ensure your thighs are parallel to the floor and your knees are level with your hips.

If you're on a budget, a rolled-up towel at your lower back can also help.

4. Awkward Keyboard and Mouse Placement

Typing with your wrists bent or reaching out for your mouse can cause wrist pain, carpal tunnel, and repetitive strain injuries.

How to Spot It:

You rest your wrists on the desk while typing.
You feel tingling or numbness in your hands or fingers.

What You Can Do:

Your elbows should be at a 90-degree angle, close to your sides.
Keep your mouse and keyboard at the same height.

Tip: Use a wrist rest or an ergonomic keyboard if you type a lot.

5. Lack of Movement or Frequent Breaks

Staying still for hours sounds harmless, but it’s a silent killer. Lack of movement can cause muscle stiffness, reduced circulation, and even blood clots.

How to Spot It:

You feel stiff when getting up.
You lose focus or feel sleepy often.

What You Can Do:

Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
Stand, stretch, or take a short walk every hour.

I once used a fitness tracker that buzzed every hour to remind me to move. It worked wonders!

6. Glare and Poor Lighting

Glare on your screen or harsh overhead lights can strain your eyes and cause headaches.

How to Spot It:

You squint at the screen.
You get headaches after working for long hours.

What You Can Do:

Adjust your screen brightness.
Use blinds or reposition your monitor to reduce glare.

Ergonomic Tip: Try a matte screen filter or use anti-glare glasses.

7. Unsuitable Desk Height

Your desk should support your arms and wrists naturally. If it’s too high or too low, your shoulders and wrists suffer.

How to Spot It:

You raise your shoulders while typing.
Your wrists bend up or down.

What You Can Do:

Adjust your chair height or use a keyboard tray.
Ensure your forearms are parallel to the floor.

8. Overreaching for Tools or Items

Frequently stretching for your phone, notepad, or mouse strains your shoulders and back.

How to Spot It:

You lean or twist your torso to grab items.
You keep standing to reach frequently used tools.

What You Can Do:

Keep items you use often within arm’s reach.
Organize your desk with purpose—what you use daily should be nearby.

9. Stress and Mental Fatigue

Believe it or not, poor workstation ergonomics can lead to mental fatigue, frustration, and stress.

How to Spot It:

You feel drained at the end of the day.
You’re irritable or less productive.

What You Can Do:

Take micro-breaks to reset.
Create a calm, clutter-free workspace.
Use calming background music or soft lighting.

Sometimes, just decluttering your desk can refresh your mindset.

10. Using Laptops Without Accessories

Laptops are great for mobility, but they’re not designed for long-term use without accessories. Hunching over them for hours is a recipe for pain.

How to Spot It:

You always bend your neck while working.
Your hands feel cramped after long laptop sessions.

What You Can Do:

Use a laptop stand to raise the screen.
Use a separate keyboard and mouse.

How Can You Fix Ergonomic Risks? A Step-by-Step Guide

Step 1: Assess Your Workstation

Sit down and look at your setup. Is everything within easy reach? Are you sitting comfortably?

Step 2: Adjust Your Chair and Desk

Make sure your knees, hips, and elbows are all at 90-degree angles.

Step 3: Monitor Placement

Align the top of your screen at eye level and at arm’s length.

Step 4: Breaks and Exercises

Set reminders to stretch or move around every hour.

Step 5: Invest in Ergonomic Tools

An adjustable chair, wrist rest, or a footrest can make a big difference.

Why Ergonomics Training Is Important

For employers and safety managers, training staff in ergonomic practices reduces absenteeism and long-term health claims. That’s why professional safety training like the NEBOSH course in Pakistan is vital.

This training teaches professionals to identify ergonomic hazards, assess risk, and implement practical control measures—making workplaces healthier and more productive.
