[UPDATED] Sleeping with Wet Hair and Other Hair Myth/Truths
I'm looking for some real scientific evidence that disproves the theory that sleeping with wet hair causes headaches.
I read this OLD thread, but it doesn't provide evidence other than a few people saying "I go to bed with wet hair all the time". For all we know they could be dead now because of their wet hair! http://www.redflagdeals.com/forums/show ... r+headache
(I did some minimal google searching, since I want to go to bed now 1am...will try something more extensive tomorrow)
I'm looking to show her that scientific method > unfounded beliefs passed from generation to generation. Any help would be great!!!
Question: What's my risk of catching a cold when the temperature drops?
Question: Is "cold feet" more than just a figure of speech?nuberific wrote: ↑Apr 10th, 2009 3:15 amAccording to Makinen et al. (2009), respiratory tract infections and common colds are associated with temperature. For upper respiratory tract infections, the association is a 4.3% increased chance of infection per 1 degree Celsius drop in temperature (p=0.055, almost statistically significant). A 1 degree Celsius drop in temperature increases the chance of getting the common cold by 2.1% (p=0.004, statistically significant). This was for a North American sample.
Mourtzoukou and Falagas' (2007) review paper indicate that the inhalation of cold air, cooling of surface body, and cooling of core temperature suppress immune respone and cause other effects that lead to increased risk of infection. Although not all sources are unanimous on this issue, it appears that's the general concensus. Further, longer duration in the cold also appears to increase the risk of dying from infections.

Poster's note: But to be fair, Makinen et al. (2009) was one of the cited papers by Mourtzoukou and Falagas (2007), so the information is a bit redundant.
