How Your Computer Causes Headaches
Completing work or study without a computer is almost unimaginable, particularly during the COVID-19 crisis when many are working from home. Unfortunately, prolonged periods of screen time can cause pain, strain and headaches. Below, we discuss the reasons for computer related headaches and some ways to alleviate the discomfort.
Eyestrain
Long periods of time in front of your bright computer screen is a workout for your eyes and the surrounding muscles. The strain on your eyes can cause pain, fatigue and headaches.
To avoid headaches caused by eyestrain, try the following:
Change your focus
After every 20 minutes of screen time, look into the distance, 20 metres away, for 20 seconds. Your eyes will thank you for this short break from focusing on your screen.
Have a break
After 2 hours of screen time, have a 15-minute break. Avoid other screens such as your phone or TV during this break. A short walk outside is the perfect break to refocus you and your eyes.
Follow instructions from your optometrist
If you have glasses to be worn for short distance use including computer work, wear them to avoid unnecessary eyestrain. If you struggle to see your screen or have noticed a change in your vision, visit your optometrist
Poor Posture
Many home offices involve the kitchen bench or the couch. While these may be comfortable in the short-term, they may not provide your neck and back with the required level of support, leading to headaches, neck pain or back pain.
Consider the following when setting up your home-office.
Your desk chair
Office chairs are designed to provide appropriate cushioning and back support to allow long periods of sitting. Sitting on a towel or blanket could offer extra comfort to your workspace. Additionally, if your chair lacks back support, roll up a towel or blanket and place it between the chair and your lower back for lumbar support
Screen height
The top of your computer or laptop screen should be just below eye level. This is the ideal position for your neck. Use a pile of books or a shoebox to achieve this
Take Breaks
Regular breaks and changes to posture can give your body the rest it needs. Stand up, move around or stretch at least once an hour
Excess Brightness
An extremely bright screen can also cause eyestrain and headaches. Glare from screens can also inhibit sleep.
The following tips may reduce glare and eyestrain due to illumination:
Reduce brightness of overhead lights
While sufficient light is beneficial to a workspace, excessive overhead light can be damaging
Natural Light
Try and work in a room with an abundance of natural light. This will have a positive impact on your eyes and your electricity bill.
