As alluded to, a team of researchers in Iran noted that the reproductive system is linked to the nasal system and, as such, have found that sex constricts blood vessels in the nose and eyes, causing your eyes to stop streaming and also helping unblock the stupidly stuffy noses.

The team at Tabriz Medical University has not yet conducted clinical trials to test their hypotheses, however, they have been researching this since at least 2019. If they are proven right, they could help reduce reliance on antihistamine drugs and make lots of people very happy.

Sina Zarrintan - one of the neurologists heading up the research - says his method would be a lot more enjoyable and cheaper than more conventional treatments, i.e. antihistamines, etc., but stressed it would not be necessary to do it all the time.

He went on to say: "It can be done from time to time to alleviate the congestion and the patient can adjust the number of intercourses depending on the severity of the symptoms."

Sceptics have, of course, ridiculed the idea; Mohammed Amin Abolghassemi Fakhree from the same university said: “There are some limitations in using ejaculation as a treatment of nasal congestion, such as not being applicable out of home and not having any sex partner."
