Man flu

The term 'man flu' is believed to have originated in the 1990s, with the earliest known use found in a message posted on the Usenet newsgroup misc.health.diabetes in 1999, as documented by the Oxford English Dictionary. An open-access poll featured in Nuts magazine in 2006 brought attention to this notion, although it was widely criticized as unscientific. The poll reported that men reported longer recovery times from flu-like illnesses compared to women, with men taking an average of three days to recover, while women recovered in 1.5 days. A poll conducted for a painkiller manufacturer in 2008 suggested that such exaggeration is just as prevalent in women. A Boots advertisement featuring the tagline "when he's ill and you don't have time to be – get cold and flu products for just 99p at Boots", which may have been inspired by the concept of 'man flu', was criticized by some for reinforcing gender stereotypes. == Scientific inquiry ==

Scientific investigation into 'man flu' and its journalistic uptake have been disorderly. Some researchers refute outright the existence of man flu, while one study has suggested substantial evidence for the phenomenon while nevertheless remaining inconclusive on the question of its ultimate existence. Moreover, other scientific studies focused on gender differences in immune responses in contexts either broader than or separate from the flu have been cited in public discussion as evidence of the existence of 'man flu'. One study, published in 2009, investigated the effects of the bacterium Listeria monocytogenes on genetically modified mice. While the study did not pertain to cold or flu viruses, but rather to a bacterial disease, it gained widespread attention and was misinterpreted by various media outlets, including The Daily Telegraph, as supporting the existence of 'man flu' in humans. In a study published in the Journal of Psychosomatic Research, researchers affiliated with the University Of Innsbruck found that while women may recover from flu symptoms more quickly than men, a uniquely severe sensitivity to the flu on the part of men does not exist. Research on influenza vaccination suggested that women may be more responsive to vaccination than men, experiencing more local (skin) and systemic (bodywide) reactions, and exhibiting a better antibody response. Testosterone levels in men were found to potentially play a role in their response to influenza vaccination, with men having the highest levels tending to show a lower antibody response. Since flu symptoms are largely attributed to the body's immune reaction, a lessened immune response in women may translate to milder symptoms. Despite such findings, this BMJ article, in keeping with the a humorous tone of the journal's Christmas edition, is not intended to imply the existence of man flu. According to researchers at the University of Cambridge, evolutionary factors may have led women to develop more rigorous immune systems than men due to differing reproductive strategies. In addition, a 2011 study conducted at the University of Queensland suggests that female hormones, such as oestrogens, aid pre-menopausal women in fighting infections, but the protection is lost after menopause. Research indicates that men are less inclined to seek medical attention when unwell and may underreport symptoms when they do. ==See also==
