While it is impossible to live completely free of stress, it is possible to prevent stress as well as reduce its effect when it can’t be avoided. The US Department of Health and Human Services offers the following suggestions for ways to deal with stress.

Try physical activity

When you are nervous, angry or upset, try releasing the pressure through exercise or physical activity. Running, walking, playing tennis, or working in your garden are just some of the activities you might try. Physical exercise will relieve your anxiety and worry and help you to relax. Your body and your mind will work together to ease the stress in your life.

Share your stress

It helps to talk to someone about your anxieties and worries. Perhaps a friend, family member, teacher or even your leader can help you a better view of what’s troubling you. If you feel your problem is serious, you might seek professional help from a psychologist or a doctor. Knowing when to ask for help is an important step in avoiding serious problems later.

Take care of yourself

You should make every effort to eat well and get enough rest. If you easily get angry and cannot sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situations. If stress repeatedly keeps you from sleeping, you should consult a doctor. Make time for yourself.

Make a list of the things you need to do

Stress can result from disorganization and a feeling that "there’s so much to do, and not enough time". Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is completed. Set out to do the most important tasks first.

Go ahead and cry

A good cry can be a healthy way to bring relief to your anxiety. It might even help you avoid a headache or other physical effect of anxiety and stress.
