Stress management can boost the immune system, help lessen the symptoms and progression of chronic diseases, and, maybe promote world peace. The three biggest and best management techniques are the hardest to follow. Watching your diet, exercise, and, if you are smoking, quitting. Substances like sugar, caffeine, salt and fat can tax the available resources the body has available to fight a stress reaction. Caffeine also can extend and magnify many of the symptoms of stress overload.
Exercise is a two pronged attack on stress.
It can give you the sheer physical relief of blowing of the tension, and, while you are doing so it helps strengthen and prepare the body for the next stressful event. Try turning your perceptions on stress around. Next time an overwhelmingly stressful situation crops up try and generate the same sense of power. Remind yourself that this is just another challenge to overcome and that you have the skills and training to do it. Practice relaxation techniques whenever you get a moment.
