Internet addiction is when someone spends too much time on the internet and finds it hard to control how much time they spend using it. It's kind of like when you eat too much candy and can't stop even though you know it's not good for you.
People might become addicted to the internet for different reasons. Some people use it to escape from their problems or because they feel lonely. Others might use it for fun or to connect with friends. Whatever the reason, it can be hard to stop using the internet once you've started.
When someone has internet addiction disorder, they might be glued to the computer screen for hours on end. They might spend less time with friends and family or neglect their other responsibilities like homework or chores. They might also feel irritable or moody if they can't use the internet.
Just like other addictions, internet addiction disorder can be harmful to a person's health and wellbeing. It can affect their sleep, cause eye strain or headaches, and even lead to depression or anxiety. So it's important to learn how to use the internet in a healthy way – maybe by setting time limits or finding other activities to enjoy.
