Talk:Infradian rhythm

From Wikipedia, the free encyclopedia

It would probably be good to also reference Ultradian and Circadian rhythms. And link to the article on Menstrual Cycles rather than describe them here.

This definition is correct according to the OED's entry on Ultradian ryhthms, the Stedman's Medical Dictionary (infradian. (n.d.). The American Heritage® Stedman's Medical Dictionary. Retrieved September 13, 2007, from Dictionary.com website:), primary sources like http://archpsyc.ama-assn.org/cgi/content/abstract/42/3/295, and just plain etymology (infra = below; in the context of waves, like light, "slower than". I.e. infrared has a longer period than red.

However, be aware that the online Merriam-Webster's medical dictionary (infradian. (n.d.). Merriam-Webster's Medical Dictionary. Retrieved September 13, 2007, from Dictionary.com website: http://dictionary.reference.com/browse/infradian) returns a contrary definition -- i.e. periods shorter than a day.

[edit] Questionable member of "rhythym" page

Should this be listed in the "rhythym" category? Everything else there seems to be musical, this isn't. —Preceding unsigned comment added by 59.101.238.220 (talk) 10:22, 15 March 2008 (UTC)
