Screen time can negatively affect physical activity levels by promoting a sedentary lifestyle. Excessive hours spent in front of screens often lead to decreased engagement in exercise and physical play, particularly among children and adolescents. This can result in a host of health issues, including obesity, cardiovascular disease, and decreased overall fitness levels. Furthermore, increased screen time can disrupt sleep patterns, leading to fatigue that further reduces motivation to be active. Encouraging breaks and active choices during screen time can help counteract these effects.
