Brace yourself-- btw I'm talking to women here, and men who are interested -- we, human females do not necessarily have to bleed (too much) during our menstruation.
I know, you're there thinking "what the f*** does that mean?!" Of course we bleed because the lining of the uterus is shed!!.. right? Or does it really have to be like that?? Thanks to Ollique's blog I've found this piece of information.
"During the days before a woman ovulates, the lining of the womb - the endometrium - thickens in preparation for a possible conception. If the egg released at ovulation passes through the womb unfertilized, the thickened endometrial tissues are not needed - and in a truly healthy woman, as in animals in their wild state, those tissues are mostly reabsorbed. What remains is expelled over a short period of time as a slight mucus discharge (2:28-29; 15:227)."source
Apparently, other wild animals do not shed massive amount of blood as we do, but rather reabsorb the lining back into their systems (source 1), (source2).
This site argues that the reason human being, and other domesticated animals have heavier flows is due to our diet, too much protein and lack of other substances. Others consider light flow menstruation a sign of illness, or drug side effects.
However, it does make me wonder, if I can really decrease the flow of my period without becoming ill, and on top of that not have cramps, that would be revolutionary. I think I will gain at least 12 if not 24 more days of my life per year!, where I can be productive and do something other than lie in bed grabbing my tummy, due to the intolerable pain. Also then could I avoid the effort of changing pads/tampons, being scared that it will leak, which it always does!, and not being able to sleep through cuz of the heavy flow - sorry for the graphical depictions here.
I can't go too much into this, but will keep you up to date with all my new findings.
But while I'm on the topic, I would also like to introduce to you a couple of more things. While I'm on the sustainable living roll these days, here are a couple of ways to not kill too many trees and not fill our planet with large amounts of non-biodegradable waste.
Lunapads: pads made of cloth - nicer feeling - which could be reused after washing.
(they also sell those devices which allow you to pee standing up called Pstyle).
Mooncups: its the reusable tampons, so to say, made of silicon, it collects menstrual blood rather than absorbing it. Also, you don't need to change it as often because, the Mooncup will hold 30ml of fluid, which is roughly one third of the average total produced each period, which is approximately 80mL.
But of course you won't even need these if you were to not bleed...
