Ice cream. Evil or not?

[koalathebear]

I was baffled when I was talking about ice cream the other day and a whole bunch of girls at work said that they couldn't eat it because they were having their period. Apparently Chinese women believe that you should not eat cold things, especially ice cream during their period. One colleague tried to tell me that when she was a teenager, she ate ice cream and accidentally stopped her period and had to go to the doctor. I was told that when you have your period, you're not even supposed to wash the dishes because the water might be cold.

I have googled this and I can't find any medical basis for the notion that eating cold things like ice cream during your period is dangerous. I must throw the poll open :)
