In order to prevent the occurrence of physiological dysmenorrhea or irregular menstruation, the older generation will tell them not to wash their hair during menstruation, not to drink cold drinks, to eat more foods that promote metabolism, not to eat too heavy things one week before the physiological period, not to stay up late, and not to do strenuous exercise. To prevent blood blockage.
In fact, western medicine has no relevant conclusions about the statement that you can't wash your hair during menstruation, or that you will get a "head wind" when washing your hair.
However, because when women have menstrual cramps, the pelvic cavity is in a state of congestion, less blood will flow to other parts of the body, and less blood will naturally flow to the head; If the scalp encounters cold water at this time, the blood vessels on the scalp will contract, reducing blood and causing poor blood circulation.
Therefore, we should pay special attention to keep warm and avoid washing our hair with cold water. If you really want to wash your hair, dry it with a hair dryer immediately after washing your hair to avoid catching cold.
In short, you can't drink cold water or eat cold food during menstruation, whether you believe it or not, it's better to be careful for your health!
