If your libido seems to have taken hiatus from the boudoir, it might be worth getting your heart rate checked. A study done on women between the ages of 18 and 39 found that those with low heart rate variability (the difference in time between heart beats) were more at risk for problems with sexual arousal and overall sexual difficulties. Beyond that, low heart rate variability has also been tied to depression, anxiety and alcohol dependence, says the study’s leader, which makes sense as to why it could suddenly bring your sex life to a thudding halt. But don’t fret. Researchers are hopeful that this link between heart rate variability and sexual dysfunction will make it easier, quicker and more cost-effective to diagnose as well as monitor treatment. If you’re experiencing any of these symptoms (libido-related or otherwise), it’s certainly worth a chat with your physician to explore what next steps to take.
