The Real Reasons You’re Tired

Drugs are sapping your energy
Side effects from prescription and over-the-counter medicines like antihistamines can secretly sap your energy. Each person reacts to allergy meds differently, and some might make you drowsy even if they’re touted as non-drowsy formulas. Many beta-blockers for hypertension are also known for causing fatigue, and certain antidepressants have the same effect.

What to do: Medicine fatigue isn’t something you always have to live with. New or different formulations may not have the same effects, so check with your doctor about switching brands, dosages, or treatments. Keep an eye on labels, too: If insomnia is listed as a side effect, don’t ignore that warning.

You have a vitamin D deficit
Today’s healthy desire to avoid sun dam­age has created an epidemic of D deficiency, says Annabelle Volgman, MD, a cardiologist and medical director of the Heart Center for Women at Rush University Medical Center in Chicago. In fact, many of her female patients complaining of fatigue and chest pain are low in D, which the body makes from exposure to sunshine. The cause of the D-deficiency-and-fatigue connection isn’t clear, but low levels of this vitamin are associated with increased risks of heart disease, high blood pressure, some cancers, and neurological disorders.

What to do: A “25-hydroxy vitamin D” test of your blood (taken from a vein at the doc’s office) can check your levels; normal is about 16 to 74 nanograms per milliliter. Although you can find vitamin D in fish, eggs, and cod liver oil, Dr. Volgman says, most women who are deficient can benefit from supplements. To beat fatigue, she recommends 10 minutes of sunshine per day. A multivitamin can deliver 800 IU, twice the recommended daily amount.
