You shouldn't wash your hair on the first day of your period.
Cold drinks should be avoided during menstruation.
...
Menstruation is a normal physiological phenomenon for women, and to some extent, it reflects their health. Therefore, everyone attaches great importance to menstruation and knows that there are many things to pay attention to during menstruation.
But are these rumors true?
Although everyone knows that menstruation is a special period and there are many things to pay attention to, they don't really know the specific precautions. What should you pay attention to during menstruation?

Sexual intercourse is not advisable
Sexual intercourse should be avoided during menstruation.
At this time, the cervix is slightly open. If intercourse occurs at this time, it is easy to introduce bacteria from the vulva and perineum into the vagina, cervix, or even invade the uterus, causing endometritis, acute adnexitis, pelvic peritonitis, etc.
Furthermore, having intercourse at this time may cause the shed endometrium to flow back into the pelvic cavity, leading to endometriosis. These conditions can cause increased menstrual flow, dysmenorrhea, or prolonged menstrual periods.

Strenuous exercise is not recommended.
During menstruation, women should also avoid strenuous exercise.
However, it's important to note that exercise isn't absolutely prohibited; it's just a matter of controlling the intensity. Activities like running or jumping should be avoided as much as possible, as they can worsen menstrual discomfort, such as lower back pain, and in severe cases, cause dysmenorrhea and menstrual irregularities.
Swimming should be avoided during menstruation, as the cervix is slightly open during this time, making it easier for bacteria to invade the uterine cavity, increasing the risk of infection and causing various gynecological inflammations.
What should you pay attention to during your period? In addition to this, you should avoid eating raw, cold, or spicy foods, keep your body, especially your abdomen, warm, and avoid getting chilled.
