Fatigue can be due to numerous causes, such as medical conditions like congestive heart failure, hypothyroidism or diabetes. It can also be a result of sleep disturbances brought on by menopause, or by physical changes that accompany aging. But while fatigue may be an inescapable part of life, there’s no need to take it lying down. Your body is geared toward generating energy as well as expending it. And there are numerous strategies to help regain the physical and mental energy needed to enjoy life to its fullest.

Eat for energy

The tried-and-true advice for healthful eating also applies to keeping your energy level high:

• Eat a balanced diet that includes a variety of carbohydrates, proteins, and fats with an emphasis on vegetables, whole grains, and healthy oils. Taking a daily multivitamin will ensure that you get the vitamins and minerals you need, but taking extra amounts of individual nutrients won’t give you more energy.

• Eating certain types of foods in particular amounts can help prevent fatigue. Because different kinds of foods are converted to energy at different rates, some — such as candy and other simple sugars — can give you a quick lift, while others — such as whole grains and healthy unsaturated fats — supply the reserves you’ll need to draw on throughout the day.

• Eat small, frequent meals. Where energy is the issue, it’s better to eat small meals and snacks every few hours than three large meals a day. This approach can reduce your perception of fatigue because your brain, which has very few energy reserves of its own, needs a steady supply.

Reduce stress

The most common cause of persistent fatigue is stress and the emotional response to it. People who feel fatigued most of the time don’t necessarily have more stress in their lives than other people, but they may be more sensitive to its effects. Stress-induced emotions consume huge amounts of energy. Relaxation therapy can be an effective tool for reducing stress and naturally boosting your energy, particularly when used in combination with cognitive behavioral therapy. Meditation, self-hypnosis, yoga, and tai chi are all relaxation techniques. One of the easiest techniques to use is progressive muscle relaxation, which involves systematically tightening and releasing sets of muscles, beginning with your toes and progressing up your legs, torso, hands, and arms. You might also consider other relaxation therapies, including aromatherapy and massage.
