Know and understand the causes of these health issues and strategies for preventing them

5 The effects of using IT

👀 Eye Strain & Computer Vision Syndrome

Your eyes are like a camera that needs to adjust focus constantly. When you stare at a screen for long periods, the lenses in your eyes work overtime, leading to fatigue, dryness, and headaches.

• 20‑20‑20 rule: every 20 minutes look at something 20 feet away for 20 seconds.
• Use proper lighting: avoid glare and keep the screen at eye level.
• Adjust screen brightness and contrast to match the room lighting.
• Use blue‑light filters or glasses to reduce eye strain.

🪑 Posture & Musculoskeletal Problems

Think of your body as a building that needs a solid foundation. Slouching or an improper desk setup can put strain on your neck, shoulders, and back.

1. Ensure your chair supports your lower back.
2. Keep the monitor at eye level, about 50–70 cm away.
3. Place your keyboard and mouse so your elbows are at a 90° angle.
4. Take a 5‑minute stretch break every hour.

🎹 Repetitive Strain Injury (RSI)

Your hands are like piano players; too much practice without rest can cause pain. Repeated key presses and mouse clicks can lead to tendon inflammation.

• Use ergonomic keyboards and mice.
• Take short breaks: 10 seconds of hand stretching every 30 minutes.
• Alternate between typing and other tasks to give your hands a rest.
• Maintain a neutral wrist position.

🧠 Mental Health & Digital Fatigue

Your brain is a battery that needs charging. Constant notifications and endless scrolling drain mental energy.

1. Set specific times for checking messages and social media.
2. Use “Do Not Disturb” mode during study or sleep times.
3. Practice mindfulness or breathing exercises to reset focus.
4. Engage in offline hobbies to balance screen time.

🛌 Sleep Disruption

Blue light from screens can shift your circadian rhythm, like a clock that gets thrown off. This makes it harder to fall asleep and reduces sleep quality.

• Turn off screens at least 1 hour before bed.
• Use blue‑light blocking settings or glasses.
• Keep your bedroom dark and cool.
• Read a physical book or listen to calming music instead of scrolling.

Remember: balance is key. By understanding the causes and applying these prevention strategies, you can enjoy technology without compromising your health.
