Over time, work stress, emotional stress, lack of sleep, poor diet, and inadequate exercise can throw your hormones out of whack, ultimately leaving you with a low sex drive. In addition, food sensitivities, environmental toxins, and certain prescription drugs can rev up the production of cortisol, the so-called “stress hormone,” which results in yet another blow to your libido. Fortunately, there’s hope for turning things around and getting your hormones—and your love life—back to normal (no drugs required).
