Long working hours for children can have detrimental effects on their physical and mental well-being. Physically, it can lead to fatigue, developmental issues, stunted growth, and potential long-term health problems due to lack of adequate rest and exercise. Mentally, it can cause stress, anxiety, depression, and hinder their educational development as they may not have enough time or energy to focus on schoolwork. Additionally, long working hours deprive children of essential playtime and social interactions crucial for their holistic development. Overall, it negatively impacts their health, education, and overall quality of life.
