Question 16 of 16intermediate🔧 ApplyLong Answer5 marks

Sumit got good marks in all the subjects. His father gifted him a laptop. He would like to make Sumit aware of health hazards associated with inappropriate and excessive use of laptop. Help his father to list the points which he should discuss with Sumit.

Correct Answer

Sumit's father should discuss the following health hazards associated with excessive and inappropriate use of laptop:

Eye Strain and Vision Problems: Continuous viewing of the screen exposes eyes to glare, leading to dry, watering, or itchy eyes. Sumit should periodically focus on distant objects and take breaks for outdoor activities to reduce eye strain.

Posture-related Issues: Sitting in an improper posture for prolonged periods can cause backaches, neck and shoulder pains. Sumit should maintain proper viewing distance and angle while working on the laptop.

Wrist and Finger Problems: Overuse of keyboards that are not aligned ergonomically can lead to painful conditions of wrists and fingers, which may require medical help in the long run.

Physical Health Impacts: Spending too much time on digital devices can lead to stress, physical fatigue, and obesity. Internet use can become addictive and negatively impact physical well-being.

Preventive Measures: Sumit should follow ergonomics — the science of designing workplaces, furniture, and equipment for safe and comfortable use. This helps reduce strain, fatigue, and injuries caused by prolonged computer use.

Explanation

This question is from the NCERT Class 11 Computer Science textbook, specifically from the chapter on societal impacts of technology. The context provides comprehensive information about health hazards including eye strain from screen glare, posture problems causing backaches and neck pain, wrist and finger conditions from keyboard overuse, and broader impacts like stress, fatigue, and obesity. The concept of ergonomics is highlighted as the preventive science. A 5-mark answer requires covering multiple health hazards with their preventive measures, structured in 4-5 paragraphs with key terms highlighted.

Solution Steps

  1. Step 1: Identify health hazards from context - eye strain, posture issues, wrist problems, stress/obesity

  2. Step 2: Extract preventive measures - ergonomics, breaks, proper posture

  3. Step 3: Structure answer in 4-5 paragraphs covering all major points

  4. Step 4: Use bold formatting for key terms like 'ergonomics', 'eye strain', 'posture'
