A Facebook post published in Nigeria tells women there are a number of things they mustn’t do during their periods, and offers other “don’ts” to avoid cancer and infertility.

In summary, the post’s advice is:

1. Women shouldn’t drink ice water or soda water during menstruation, or eat coconut. It claims “research proves” that drinking ice water can “cause menstrual blood remaining in the uterine wall” and lead to “uterus cancer or tumour” after five to 10 years. No reason is given for avoiding soda water and coconut.

2. It tells women not to use shampoo during their periods “because the pores of the head are open during menstruation and it can cause headache”. This, it says, is “very dangerous” and the effects “can be felt when young and later when aged”.

3. Women mustn’t eat cucumbers when they’re menstruating, the post says, because “the sap present in the cucumber can block some menstruation (blood waste) in the uterine wall”, which could cause barrenness.

4. Finally, the advice goes, women’s bodies “should not be knocked or hit by hard objects, especially the abdomen” because it could cause them to vomit blood, and the uterus could be injured. This, it says, is the “origin” of cancer of the uterus, as well as of “cysts and barrenness”.

We fact-checked these and here's the verdict: https:///2EQBL2z
