Prolonged screen use can cause eye strain, back pain, and fatigue. Experts say it's not the screens, but how and how long we use them.
Health risks of prolonged screen use
Prolonged time spent in front of a screen can lead to various health issues, including eye irritation, back stiffness, decreased concentration, and fatigue. These problems are not caused by the screen itself but by how long it is used and the conditions under which it is used.Visual fatigue and its symptoms
Extended screen work can cause visual fatigue, characterized by symptoms such as tingling, a feeling of heaviness in the eyes, temporary blurred vision, or headaches. This often occurs due to decreased blinking and prolonged visual effort when reading or switching between windows.Contributing factors to discomfort
Several factors can worsen discomfort during screen use, including inadequate lighting, screen reflections, small or hard-to-read characters, and prolonged work without breaks. These conditions increase the strain on the eyes and body.Mental and cognitive demands
Working in front of a screen requires significant mental effort, such as managing multiple tasks, responding to emails, or handling urgent requests. Frequent interruptions and task changes can increase the overall workload and stress levels.Physical strain from static postures
Staying in one position for long periods can cause physical strain, including pain in the neck, shoulders, back, and wrists. Poor posture, improper screen placement, and repetitive use of the keyboard and mouse can contribute to these issues.Long-term health effects of sedentary work
Prolonged sitting can lead to less visible but serious health consequences, such as weight gain, metabolic disorders, and cardiovascular diseases. A poor work environment, including uncomfortable lighting or seating, can further exacerbate these risks.Blue light and other factors
While blue light from screens is often blamed for fatigue, it is not the sole cause of all symptoms. Factors like the duration of screen use, the nature of the tasks, and the overall working conditions play significant roles in discomfort.Recommendations to reduce screen fatigue
To reduce screen-related fatigue, it is recommended to take regular breaks, such as following the 20-20-20 rule, which involves looking at an object 6 meters away for 20 seconds every 20 minutes. Adjusting the workstation, limiting interruptions, and moving regularly can also improve comfort.When to seek medical help
If symptoms like frequent headaches, persistent blurred vision, dry or painful eyes, or recurring pain in the neck, back, or shoulders persist, it is advisable to consult a health professional for further evaluation and treatment.
