GMC Srinagar Advisory: Excessive Screen Time Harms Physical, Mental and Emotional Health

The Department of Community Medicine at Government Medical College (GMC) Srinagar has issued a public awareness advisory warning that prolonged screen time causes significant physical, mental, and emotional health problems. The advisory states that excessive use of smartphones, tablets, and computers contributes to health issues across all age groups, with children, adolescents, and young adults being particularly vulnerable.

What are the physical risks of excessive screen use?

Digital Eye Strain is one of the most common consequences of extended screen use without breaks, according to the advisory. Medical experts noted that screen use can reduce the natural blinking rate by 50 to 60 per cent.

This reduction leads to fatigued, irritated, and dry eyes. Symptoms include blurred vision, burning sensations, headaches, and pain in the shoulders and neck.

The advisory also identifies “Tech Neck,” a condition resulting from poor posture. While the human head typically weighs about 5 kilograms, tilting it forward 45 to 60 degrees to view a device increases the effective load on the neck to over 20-25 kilograms.

This strain on the cervical spine may lead to shoulder stiffness, chronic back and neck pain, and early spinal degeneration, the advisory states.

Did You Know? When a person tilts their head forward at a 45 to 60-degree angle to look at a phone, the load on the neck can increase from a typical 5 kilograms to more than 20-25 kilograms.

How does screen time affect sleep and brain development?

Screens emit blue light that suppresses melatonin, the hormone that regulates sleep. According to the advisory, this disrupts the circadian rhythm and leads to reduced sleep quality and delayed sleep onset.

These disruptions can result in daytime fatigue, insomnia, mood-related issues, and poor concentration. The advisory warns that these effects impact overall emotional well-being.

For children, excessive exposure may interfere with critical social, language, and cognitive brain development. This could lead to weaker executive functioning skills, reduced attention spans, and delayed language development.

The advisory further links high screen exposure in childhood to lower academic performance.

Expert Insight: Samantha Carter suggests that the advisory highlights a critical trade-off between digital integration and physiological health. The shift toward sedentary screen habits doesn’t just impact vision, but potentially alters the fundamental developmental trajectory of children’s cognitive and social skills.

What are the long-term psychological and metabolic consequences?

Health professionals cited in the advisory expressed concern over declining physical activity. Sedentary screen time contributes to weight gain and reduced fitness levels.

This lifestyle increases the risk of cardiovascular diseases, hypertension, obesity, and Type 2 diabetes. The advisory connects these physical risks to a lack of movement.

Psychologically, high screen time is linked to increased levels of stress, anxiety, and depression. The advisory also notes a rise in loneliness and reduced self-esteem among users.

How can people reduce the health risks of digital devices?

The department recommends the 20-20-20 rule: every 20 minutes, look at an object 20 feet away for 20 seconds. They also suggest taking movement breaks every 30 to 60 minutes.

Doctors share 'screen time' health risks

Users are advised to maintain proper posture and avoid screens one to two hours before bedtime. Balancing digital activities with physical exercise and outdoor recreation is also recommended.

The advisory concludes by urging people to limit recreational screen time, stating, “Your body was designed to move, not to scroll continuously. Use screens. Don’t let screens use you.”

What may happen next?

Based on these warnings, public health initiatives may likely increase their focus on digital hygiene education in schools. There could be a rise in the adoption of the 20-20-20 rule in workplace wellness programs to combat Digital Eye Strain.

Medical providers may also see a possible increase in patients seeking treatment for “Tech Neck” and related cervical spine issues as awareness of posture-related strain grows.

Frequently Asked Questions

What is the 20-20-20 rule?
It is a recommendation to look at an object 20 feet away for 20 seconds every 20 minutes to minimize health risks associated with screen use.

How does blue light affect the body?
According to the advisory, blue light suppresses the production of melatonin, which regulates sleep, leading to disrupted circadian rhythms and poor sleep quality.

What is “Tech Neck”?
Tech Neck is a condition caused by poor posture while using digital devices, where tilting the head forward increases the load on the cervical spine, potentially leading to chronic pain and spinal degeneration.
