As we all know with growing age several changes occur in both girls and boys. In girls, one of the change is menstruation or in simple words periods.
If we talk in simple language, girls and women have periods due to some hormonal changes in their body. Now, the first question came to our mind is How girls bleed? Wall of uterus prepare itself to provide nourishment to the fertilized egg or ovum. But if there is no fertilized egg the lining of uterine wall break down and start shedding blood.
Menstrual cycle is repeated after every 28days. The average time of menstruation or periods in a normal case is 3-7 days. According to a study, quantity of released blood is 35-40 ml total and the capacity of a sanitary napkin/pad is 5-7 ml. Therefore, according to capacity only 7-8 napkins are required. But this is very unhygienic and dangerous. Mostly girls use a single napkin for 10-12 hours which is very risky. The time period of wearing a single napkin is 6-8 hours. More than this blood starts reacting and bacteria start building up which may cause several infections including vaginal infections. For healthy vagina regular cleaning is must but it becomes more important during periods. Because the blood starts reacting with chemicals and perfumes used in the napkins. So cleaning vagina while changing the napkin is necessary. Some girls are uncomfortable, feels unhygienic and are afraid of stains while using sanitary napkins. So they can use tampons or menstrual cups. Menstrual cups are made up of silicon and are non reactive to blood and inner region of blood and are reusable. It is believed that girls and women should not wash their hairs during periods, some girls thought that this is only a superstition and wash their hairs during periods but this is very dangerous and in some cases life threatening. It has a scientific reason, washing hairs during periods causes swallowing in the walls of uterus which becomes permanent. And it may cause complications during delivery (giving birth to a child) due to which the mother may be die, therefore, try not to wash hairs during periods. This is all about the physical health during periods
