less blood flow

The short and simple answer to your question is there is absolutely no need for you to want to “improve” your blood flow. One of the most common myths about the menstruation that it "removes bad blood and cleans your system". That is utter non sense. You must actually thank your stars that you have fewer problems and costs in managing your periods. Of course there are exceptions when it can be a sign of problems but in the vast majority of cases it is a variation of normal. And if there is a problem, surely home remedies wont be enough!

The details

Bloodletting has been regarded as therapeutic in most ancient sciences of medicine. Ayurveda recommends leeches to draw impure blood from your body. Whilst it has a role even in modern medicine (treatment of venous ulcers), it has no value as a general treatment for good health. Ancient Greeks as well as Romans believed in bloodletting. The point is bloodletting like catharsis has been seen as good for health. On most occasions its entirely unscientific and unnecessary.

I can imagine why menstruation has been considered to be cleansing for . During the periods the woman feels terrible and afterwards feels remarkable better. These ancient physicians attributed that to the benefit of letting out bad blood.

Secondly menstrual blood does look a bit different to real blood. After all, it has spent more than few hours in the uterus and then the vagina and has been degraded by protein dissolving enzymes. It is a good culture medium and has been acted upon by vaginal bacteria thus has a strong smell. This and its color which is not exactly refreshingly red, was enough for us to declare that it is the impure blood. It is then logical for women as around to think that their periods are nothing but bad blood and as a corollary more affect the better. The fact is all this is not true.

Every woman losses 80 mil-120 mils of blood each month in her periods. That is less than a third a can of coke. This amount will change from woman to woman based on how big her uterus is which in turn is based on her own size as well as how many children she has had (that increases the size of the uterus). Larger the uterus more the bleeding.

Having light periods (also called hypo-menorrhoea) can be a symptom of a few problems. However those are extremely uncommon. Tuberculosis infection of the endometrium (which is quite uncommon) or an overzealous curettage operation (following abortion etc.) could cause serious loss of endometrium and fibrous adhesions (Asherman's syndrome) which in turn can cause hypo-menorrhoea. However these causes will account for less than 1% of all cases of hypo- menorrhea. They are the exception not the rule.

The vast majority of cases wherein women think she has less periods is entirely a mismatch of what she thinks is normal and the reality.
