Health Hazards of Prolonged Computer Usage

1 Feb 2023

Computer usage has become a quintessential part of modern life, but it has also become a major source of health problems. With people spending hours each day staring at screens, computers have become a contributor to a number of negative health effects.

Let's dive into some of the ways in which prolonged computer usage can impact your health and what you can do to minimize the harm.

Eye strain

The blue light emitted by computer screens can be hard on the eyes, causing eye strain and fatigue. This can lead to symptoms such as headaches, dry eyes, blurred vision, and double vision. People who spend a lot of time reading or working on a computer are particularly vulnerable to these effects.

To reduce eye strain you should:

  • Take breaks every 20-30 minutes.
  • Look away from the screen and focus on a distant object.
  • Use an anti-glare screen or filter (blue light filter) on your computer.

Poor posture

Sitting at a computer for long hours can cause poor posture, leading to problems with the neck, back, and shoulders. Slouching or hunching over the keyboard can put pressure on the spine, leading to back pain, headaches, and other health problems.

To avoid poor posture:

  • Make sure your chair and desk are ergonomically designed (Herman Millers are a great example).
  • Take breaks every hour or so to stand up, stretch, and move around.

Carpal Tunnel Syndrome

Repetitive motions, such as typing or clicking a mouse, can lead to the development of Carpal Tunnel Syndrome, a condition that affects the hands and wrists. Symptoms include numbness, tingling, and pain in the hands and wrists.

To avoid CTS:

  • Take breaks from repetitive motions.
  • Stretch your hands and wrists regularly.
  • Use an ergonomic keyboard and mouse.

Sleep problems

Spending long hours on a computer can disrupt your sleep pattern, leading to sleep problems such as insomnia. The blue light emitted by computer screens can interfere with the production of the sleep hormone melatonin, making it difficult to fall asleep at night.

To reduce the risk of sleep problems:

  • Avoid using electronic devices for at least an hour before bed.
  • Use blue light-blocking software on your computer.


Sitting for long hours at a computer can lead to weight gain, as people tend to be less physically active when they spend a lot of time in front of a computer. This can increase the risk of obesity and other health problems, such as heart disease and diabetes.

To avoid unwanted weight gain:

  • Make sure to get up and move around regularly
  • Incorporate physical activity into your daily routine.

Excessive computer usage can harm your health through eye strain, poor posture, sleep issues and obesity. To reduce these negative effects, take frequent breaks, stretch and move, and maintain proper posture while using a computer. Being aware of these health risks allows you to maintain good health while enjoying the benefits of technology.
