Fatigue is a common symptom of many illnesses, including diabetes, heart disease, arthritis, anemia, thyroid disease, and sleep apnea. Talk to your doctor if you feel unusually tired. Many medications can contribute to fatigue. These include some blood pressure medicines, antihistamines, diuretics, and other drugs. If you begin to experience fatigue after starting a new medication, tell your doctor. Drink plenty of water. Dehydration zaps energy and impairs physical performance. “Our research shows that dehydration makes it harder for athletes to complete a weight lifting workout,” says Dan Judelson, PhD, assistant professor of kinesiology at California State University at Fullerton. “It’s reasonable to think that dehydration causes fatigue even for people who are just doing chores.” Dehydration has also been shown to decrease alertness and concentration. How to know if you’re drinking enough water?“Urine should be pale yellow or straw colored,” Judelson says. “If it’s darker than that, you need to drink water.” Get to bed early. Lack of sleep increases the risk of accidents and is one of the leading causes of daytime fatigue. The solution: Get to bed early enough for a full night’s sleep. When people enrolled in a 2004 Stanford University study were allowed to sleep as long as they wanted, they reported more vigor and less fatigue. Good sleep habits may also have important health benefits. Centenarians report better than average sleep. If you do fall short on shut-eye, take a brief afternoon nap. Napping restores wakefulness and promotes performance and learning. A 10-minute nap is usually enough to boost energy. Don’t nap longer than 30 minutes, though, or you may have trouble sleeping that night. A nap followed by a cup of coffee may provide an even bigger energy boost, according to the American Academy of Sleep Medicine.
