Many students have so many electronic devices that they spend too much time on their phones and computers. They often stay up late, eat junk food, and don't exercise enough. This can make them feel tired, get sick easily, and even have trouble studying. But we can make small changes to live a healthier life! For example, we can do outdoor activities like running or playing basketball for 30 minutes every day. We should also eat more vegetables and fruits, and drink enough water. Remember: "A healthy body keeps a healthy mind!"
