     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, and working in your garden are just some of the activities you might try.

     ◆Take care of yourself

     You should make every effort to eat well and get enough rest. If you easily get angry and can't 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

     Schedule time for both work and entertainment. Don't forget, play can be just as important to your overall

well-being as work. You need a break from your daily routine to just relax and have fun. Go window-shopping

or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.

     ◆Make a list of things to do

     Stress can come 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 task first.
