Health experts are advising Nigerians to limit excessive screen time, warning that spending long hours on smartphones, computers, tablets, televisions, and other digital devices may negatively affect physical, mental, and emotional well-being.
According to medical professionals, digital devices have become an essential part of modern life for communication, education, work, and entertainment. However, prolonged screen use without adequate breaks can contribute to a variety of health problems affecting people of all ages.
Doctors explain that one of the most common effects of excessive screen time is digital eye strain. Individuals may experience dry eyes, blurred vision, headaches, eye fatigue, or difficulty focusing after spending extended periods looking at screens. Taking regular breaks and adjusting screen brightness can help reduce these symptoms.
Health experts also note that prolonged screen use often encourages a sedentary lifestyle, which is associated with an increased risk of obesity, heart disease, type 2 diabetes, high blood pressure, and other chronic health conditions. Long periods of sitting may also contribute to poor posture, neck pain, shoulder discomfort, and lower back pain.
Medical professionals warn that using electronic devices late into the evening can interfere with healthy sleep patterns. The light emitted from screens may reduce the production of melatonin, a hormone that helps regulate sleep, making it more difficult to fall asleep and obtain restorative rest.
Doctors encourage adults and children to take regular breaks from screens by following simple habits such as looking away from the screen every 20 minutes, standing up to stretch or walk around every hour, and engaging in outdoor activities or hobbies that do not involve electronic devices.
Experts recommend creating screen-free periods during the day, especially during family meals and before bedtime. Reducing screen use in the hour before sleep may improve sleep quality and support overall physical and mental health.
Health professionals also advise maintaining good posture while using digital devices. Screens should be positioned at eye level, chairs should provide adequate back support, and wrists should remain in a comfortable position to reduce strain on the neck, shoulders, and spine.
Doctors encourage parents to monitor children’s screen time and ensure that recreational screen use is balanced with physical activity, social interaction, reading, and adequate sleep. Developing healthy digital habits early in life can contribute to better long-term health.
Medical experts conclude that digital technology offers many benefits, but excessive screen time can have significant health consequences when not properly managed. They encourage Nigerians to use electronic devices responsibly, take regular breaks, remain physically active, and maintain healthy sleep habits to support overall well-being.
