Having sex can flavor our nights, and days, with sweet pleasure and excitement, relieving stress and worry. And, of course, sex has been key to ensuring that the human race lives on. Recent studies have shown that it can have an effect on how much we eat, and how well the heart functions. As we have reported on Medical News Today , sex has been cited as an effective method of burning calories , with scientists noting that appetite is reduced in the aftermath. Also, a study published in the Journal of Health and Social Behavior in found that women who have satisfying sex later in life might be better protected against the risk of high blood pressure. Many of the effects of sex on the body are actually tied to the way in which this pastime influences brain activity and the release of hormones in the central nervous system. Here, we explain what happens in the brain when we are sexually stimulated, and we look at how this activity can lead to changes in mood, metabolism, and the perception of pain.

In a supportive relationship, there are many benefits to having more sex. Higher rates of sexual activity are linked to positive changes, such as lower blood pressure, reduced stress, greater intimacy , and even a lower divorce rate. A study found that general well-being is associated with sexual frequency, but only to an extent. One sexual encounter per week is fairly consistent with the current average. However, our increasingly busy lives may be getting in the way of having more sex.

Or, at least not-so-favorable aftermath, like sexually transmitted infections STIs or unwanted pregnancy. Still, we want you to know exactly what to expect physically and emotionally during sexual activity, and right after. Thanks to increased blood flow and heart rate — and the rush of hormones and endorphins — sexual activity affects the body from head to toe. If you have a vagina and are being penetrated during the act, expect to feel a feeling of fullness, says Reeves.
