Ask AI: Why I have headache particularly in the left side of my head after spending hours before monitor?

Spending hours staring at a monitor can result in a headache, particularly on one side, for several reasons: 1. Eye strain: Staring at a monitor for extended periods can strain your eye muscles, causing headaches, especially if you're not taking regular breaks. 2. Poor posture: Sitting in the same position for a long time can lead to poor posture, which can cause tension and pain in the neck, shoulder, and head muscles, causing one-sided headaches. 3. Improper monitor setup: An incorrect monitor height or angle can force your head and neck into unnatural positions, causing muscle tension that contributes to headaches. 4. Screen brightness and contrast: Very bright or poor screen contrast can cause eye strain, which can trigger headaches. 5. Blue light exposure: Exposure to blue light emitted by monitors can also cause eye strain and headaches. To minimize the risk of headaches, try the following: 1. Take regular breaks: Follow the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds. 2. Adjust your monitor: Position your monitor at eye level, about an arm's length away, and tilt it slightly upwards. 3. Modify screen settings: Adjust the brightness, contrast, and text size to comfortable levels. 4. Use blue light filters: Enabling a built-in blue light filter on your device or using a screen protector can reduce eye strain. 5. Maintain good posture: Sit upright with your back well-supported, and ensure your arms and wrists are at a comfortable height for typing. 6. Stay hydrated: Dehydration can contribute to headaches, so drink plenty of water throughout the day. 7. Stretch regularly: Stretch your neck, shoulders, and back during breaks to relieve tension. If your headaches persist, consult a healthcare professional to rule out any underlying issues.
