Excessive computer usage can lead to physical, social, and emotional problems. Physically, it can cause issues like back pain, headaches, and sleep deprivation from long periods sitting and incorrect posture. Socially, it reduces real-world interaction and harms relationships and social skills. Emotionally, constant gaming can increase stress, depression, and prevent people from responsibilities, potentially even leading to job loss or suicide in serious cases. Moderation of computer use is important to avoid these negative consequences.
