Death can occur during sexual intercourse for a number of reasons, generally because of the physical strain of the activity, or because of unusual extenuating circumstances. There are various euphemisms for death during sex, including "dying in the saddle" or the French "la mort d'amour " (lit. ' death of love ' ).[ 1]
Sexual intimacy, as well as orgasms, increases levels of the hormone oxytocin, also known as "the love hormone", which helps people bond and build trust.[ 2] [ 3] [ 4] Sexual activity is also known as one of many mood repair strategies, which means it can be used to help dissipate feelings of sadness or depression.[ 5]
A 2011 meta-analysis in the Journal of the American Medical Association found that each additional hour of sexual activity per week resulted in an increased risk of 2–3 myocardial infarctions and one sudden cardiac death [SCD] per 10,000 person-years.[ 6] Sexual intercourse can also trigger a subarachnoid hemorrhage via the Valsalva maneuver.[ 7] [ 8] A 2011 meta-analysis published in Journal of Sexual Medicine found that men who were unfaithful were significantly more likely than those who were faithful to experience severe or fatal cardiac events during sex.[ 9] Basilar artery dissection has also been reported in connection with sexual activity, though most coital cephalalgia is benign in nature.[ 10]
