Cybersickness: Feeling Ill From Your Screen Time.

Have you ever felt nauseous or dizzy after spending a long time scrolling through your phone or playing video games? If so, you might have experienced cybersickness. This condition, similar to motion sickness, occurs when there’s a mismatch between the signals your brain receives from your eyes and inner ear.

Understanding the Sensory Mismatch

Our sense of balance relies on two main systems: vision and the vestibular system. The vestibular system, located in the inner ear, detects head movements and sends signals to the brain about our spatial orientation. Vision, on the other hand, provides information about what we see, including movement. In a healthy state, these two systems work together seamlessly.

However, when using digital screens for extended periods, a conflict can arise. For instance, in a fast-paced video game, your eyes might perceive rapid movement on the screen (like flying or running), while your inner ear senses no corresponding movement because your body remains stationary. This disconnect between visual and vestibular information confuses the brain, leading to cybersickness symptoms.

Symptoms of Cybersickness

Cybersickness shares many characteristics with motion sickness. Here are some of the telltale signs:

• Nausea and dizziness: These are the most common symptoms, often accompanied by a feeling of unease or disorientation.
• Headaches: Focusing on a screen for a long time can strain the eye muscles, leading to headaches.
• Eye strain: Dry, itchy, or irritated eyes are a frequent complaint of cybersickness sufferers.
• Sweating and fatigue: In severe cases, cybersickness can cause cold sweats and general fatigue.

Preventing Cybersickness

The good news is that cybersickness is largely preventable. Here are some tips to minimize your risk:

• Limit screen time: Take frequent breaks, especially during long stretches of digital engagement. See Regular VDU Breaks.
• Adjust screen settings: Reduce brightness and adjust contrast for a more comfortable viewing experience and to avoid digital eye strain.
• Focus on distant objects: Look away from the screen periodically and focus on something far away to give your eyes a break.
• Maintain good posture: Sit up straight and avoid slouching to prevent neck and shoulder strain which is known as Tech Neck.
• Consider VR with caution: Virtual reality can be a significant trigger for cybersickness. Start with short VR sessions and gradually increase the duration as your tolerance improves.
• Stay hydrated: Drinking plenty of water can help alleviate headaches and dizziness.

If you experience persistent symptoms despite taking precautions, consult a healthcare professional to rule out any underlying medical conditions.

Conclusion

Cybersickness is a growing concern in our increasingly digital world. By understanding the causes and implementing preventive measures, you can enjoy screen time without feeling ill. Remember, taking breaks, adjusting screen settings, and maintaining good posture are key to a comfortable and healthy digital experience.
