Having sex (with someone you love)
According to von Borstel having sex is one of the most beneficial exercises you can do for your heart. He explains that, “As well as sex being an entire cardiac workout, before and during intercourse there is a big release of hormones that have a protective effect on our cardiovascular system.”  Having sex with someone you love, rather than a stranger, is far better for hearts because genuine affection causes the release of higher levels of oxytocin.  Oxytocin, which is sometimes referred to as the cuddle hormone is released during orgasm, and it’s proven to lower blood pressure, promote the healing of wounds and reduce stress. Endorphin, another hormone which is released during sex helps to lower heart rate and blood pressure to the heart muscle during exercise.
A recent study done by Michigan State University found women over 50 who had regular sex tended to have lower blood pressure, and so a lower risk of heart problem.
High cholesterol causes fatty deposits in blood vessels to attach to artery walls, causing clogging and arteriosclerosis, which leads to heart disease and stroke, says von Borstel, who recommends having “as much loving sex as possible”.
