How often should sanitary napkins be changed? Scientific protection of menstrual health

During women's menstrual period, sanitary napkins are important products for keeping private parts clean and healthy. But do you know how often sanitary napkins should be changed? This is not just a small detail, but a major issue related to women's physiological hygiene and health.

Normally, it is recommended to change sanitary napkins every 2-4 hours. This is because over time, a large amount of menstrual blood will accumulate on sanitary napkins, and blood is a good culture medium for bacterial growth. If it is not changed for a long time, bacteria will multiply in a warm and humid environment, which may cause itching and odor in the private parts, and even increase the risk of gynecological inflammation.

On days with heavy menstrual flow, such as the second and third days of menstruation, it may be necessary to change it more frequently, perhaps every 1-2 hours, to ensure that the sanitary napkin always maintains good absorption performance and avoids menstrual blood overflow. In periods with less menstrual flow, such as when the menstrual period is about to end, do not leave it unchanged for a long time because of the small amount of menstrual blood. It is still necessary to change it every 4 hours or so.

In addition, in some special cases, the frequency of replacement should also be increased accordingly. For example, after strenuous exercise, when the body sweats a lot, or when in a high temperature environment for a long time, the sanitary napkin should be replaced as soon as possible to keep the private parts dry and breathable. Also, when there is any discomfort in the private parts, such as itching or burning, no matter how long the sanitary napkin has been used, it should be replaced immediately, and the private parts should be checked for abnormalities, and medical treatment should be sought in time if necessary.

Correctly and timely changing sanitary napkins is a key link in women's menstrual care. Only by developing a good habit of changing can gynecological diseases be effectively prevented, so that women can stay healthy and comfortable during their menstrual period.
