Believe it or not, Post-Orgasmic Illness Syndrome (POIS) is a thing. According to Rare Diseases, it’s a “rare condition in which a person develops flu-like and allergy symptoms after orgasm, whether with a partner, through masturbation, or spontaneously during sleep.” Symptoms may develop within seconds, minutes or hours after orgasm and can last for 2 to 7 days before going away on their own. It can include anything from fatigue, weakness to a stuffy nose, sore throat and fever.
It might sound bizarre, but an article in the Journal of the Royal Society of Medicine found that sneezing in response to orgasm is surprisingly common. Apparently the condition is a result of stimulation of the parasympathetic nervous system, triggering sneezing post-climax.
Of all the side effects, having an orgasm only to sink back into a woeful headache is not pleasant. According to the Mayo Clinic, “sex headaches are brought on by sexual activity - especially an orgasm. You may notice a dull ache in your head and neck that builds up as sexual excitement increases. Or, more commonly, you may experience a sudden, severe headache just before you during orgasm.” For the most part, headaches are pretty common and nothing to be worried about, but if you feel symptoms persist, it could be the sign of underlying issues, such as problems with the blood vessels that feed your brain. As the Mayo Clinic noted, “Some people who have sex headaches will experience them in clusters over a few months, and then go for a year or more without having any sex headaches. Some people may only have one attack during their lives.”
Due to the powerful release of hormones that follows orgasm, crying is a common side effect. Known as post-coital dysphoria, the condition refers to sadness after sex. A recent study conducted with female university students even found that 46 per cent of respondents reported experiencing PCD symptoms at least once in their lifetime. But the research found there was no link between PCD and the amount of intimacy in close relationships, so don’t fear the tears are saying something about your relationship, it’s likely that you emotions are just running wild.
