Here are a few ways this can happen:
1. Cardiac Arrest
A study conducted by a leading American medical journal has revealed that each additional hour of s*xual activity per week resulted in an increased risk of 2-3 myocardial infarctions (heart attacks) and one sudden cardiac death per 10,000 person.
Experts say that indulging in s*xual intercourse can trigger a subarachnoid haemorrhage i.e. is bleeding into the subarachnoid space – the area between the arachnoid membrane and the pia mater surrounding the brain via the Valsalva maneuver. The Valsalva maneuver is performed by moderately forceful attempted exhalation against a closed airway, usually done by closing one’s mouth, pinching one’s nose shut while pressing out as if blowing up a balloon.
A study also found that the “deceased is usually married; he is not with a spouse and in unfamiliar surroundings,” and death usually occurs after “a big meal with alcohol.” So, men who were unfaithful were significantly more likely than those who were faithful to experience severe or fatal cardiac events during s*x. A related study seemed to support the death during extramarital s*x theory. Fourteen of the 20 cases of coital death, happened during an affair. “Dying in the saddle” is another popular euphemism for death during s*x.
4. S*x Drugs
Viagra use has been linked to sudden cardiovascular death during s*xual activity among elderly or otherwise infirm men. Researchers also say that prescription or recreational drugs, such as cocaine can also possibly contribute to unexpected deaths during consensual s*x.
