Just in case you needed further motivation to exercise, researchers have found that exercising on a regular basis can often improve your sex drive. This effect is thought to be a result of several factors. Physiologically, exercise promotes cardiovascular fitness, and improves circulation, which alone may benefit sexual functioning, since arousal is dependent on proper blood flow. In addition, being active may cause your body to produce more sexual hormones. Exercise has psychological side effects, too. People who work out tend to be more aware of their bodies, and have a better body self-image. Regular physical activity can also relieve stress, and stimulate the release of feel-good chemicals called endorphins, both of which might make it easier to ‘get in the mood.’ If your reason for exercising is to lose weight, build muscle, or just tone up, it’s natural to feel sexier as you approach these goals. However, keep in mind that extreme levels of exercise can cause physical and hormonal changes that may actually reduce your sex drive, and put an unnatural strain on your body.
