Get plenty of rest, but don't overdo it. If you are like most people, you associate feelings of fatigue with the need for more rest. However, studies show that too much rest can cause a drop in your body's ability to produce energy. In other words, the more you rest, the more tired you feel. One thing you might try to do when you feel tired is to spend less time lying down and more time sitting or standing, even walking or performing other activities whenever possible.
Many people find that light exercise, such as walking, actually decreases their fatigue.
Consult with your health care provider about the best form and type of exercise for you. Short periods of rest are best. When you need rest, sit or lie down more often, but only for short periods of time rather than long periods of time. Your heart rate slows down more quickly at the start of a rest period and more slowly as you continue to rest. Thus, several short rests give your heart more opportunities to beat slower and to help you to conserve your energy.
