    Stress is a feeling you can have both in your mind and in your body. It can make you want to eat less, and not talk to your friends and family.

    A little stress in life is normal. But controlling stress is important because if you feel stressed for too long, it can seriously affect your body. Older people who have stress for a long time can develop heart disease, high blood pressure and other serious health problems.

    The good news is, it can be very easy to control stress. Here are three tips:

    Tip 1: Try to eat right. Some people who feel stressed try to feel much better by eating chocolate, ice cream and other sweets. A little sugar isn't bad for you, but don't stop eating fruit and vegetables.

    Tip 2: Exercise regularly. People who are very busy with jobs or family life can feel tired a lot. Getting regular exercise can give you more energy and help you think about the things in your life that give you stress.

    Tip 3: Most importantly, watch out for each other. Stress can make you feel lonely. It's important to watch out for stress in people that are close to you: friends look out for friends, teachers look out for students.
