Review Questions

• How does excessive screen time during adolescence impact physical health?
  • Excessive screen time can lead to a sedentary lifestyle, which increases the risk of obesity and related health issues in adolescents. When young people spend too much time in front of screens, they are less likely to engage in physical activities. Additionally, prolonged screen use often leads to unhealthy snacking habits and disrupted sleep patterns, further exacerbating health problems during this critical period of growth.
• Discuss the relationship between screen time and sleep quality in adolescents.
  • Screen time significantly impacts sleep quality in adolescents due to factors like blue light exposure from screens, which can interfere with the body's natural sleep-wake cycle. When screens are used before bedtime, they can delay the onset of sleep and reduce total sleep duration. Poor sleep quality can affect mood, cognitive function, and overall well-being, highlighting the need for managing screen time, especially in the hours leading up to sleep.
• Evaluate how cultural perceptions of screen time influence adolescent behavior regarding nutrition and exercise.
  • Cultural perceptions around screen time can play a crucial role in shaping adolescent behavior concerning nutrition and exercise. In cultures where technology is highly integrated into daily life, there may be a normalization of high screen usage, leading to less emphasis on outdoor activities and physical exercise. This can result in poor dietary choices influenced by the types of media consumed online. Conversely, cultures that prioritize active lifestyles may encourage reduced screen time and promote balanced nutrition, showing how societal values directly impact adolescent health outcomes.
