Sex benefits last up to 48 hours after intercourse

It's called "sexual afterglow". It is the feeling of well-being experienced after sexual intercourse that seems to be rather long lasting, according to a study published in the journal Psychological Science by a team of scientists from the US Association for Psychological Science. Apparently, the well-being felt by a couple can last up to two days after intercourse, especially if partners have a good rapport and have been together for some time. One of the study authors and a Florida State University researcher, Andrea Meltzer. commented: “Our research shows that sexual satisfaction remains elevated 48 hours after sex. . And people with a stronger sexual afterglow – that is, people who report a higher level of sexual satisfaction 48 hours after sex – report higher levels of relationship satisfaction several months later”. The explanation of the phenomenon is linked to an evolving relationship. Usually, stable couples do not have sex daily. Meltzer and his colleagues speculate that the extended “sexual afterglow” serves to maintain a stable and strong relationship in the days between intercourse. To understand this, scientists examined data from two different studies, related to 96 and 118 couples. For two weeks, participants were asked to complete a daily diary in which they reported the frequency of intercourse and their general and sexual satisfaction as a couple. The result was that, on average, the couples had sex four days out of 14, and that every sexual intercourse was followed by an increased satisfaction in the next two days: Meltzer concluded: “This research is important because it joins other research suggesting that sex functions to keep couples pair bonded”.
