Introduction

In general, swimming during menstruation is not recommended, especially during the days with heavy menstrual flow. To avoid infection and discomfort, it's best to wait until your period has completely ended and your body has returned to normal before swimming. During your period, you may choose mild exercises such as walking or yoga, which help keep you active without negatively affecting menstrual health. The choice of exercise should be based on your personal physical condition and comfort level.

Generally, swimming during menstruation is not recommended, especially during the days with heavy menstrual flow. The specific reasons are as follows:

During menstruation, the endometrium sheds and creates an open surface within the uterus, while the cervix remains relatively open. This temporarily reduces the reproductive tract's natural defense mechanisms. Swimming pool water is not a sterile environment and may contain bacteria, viruses, and other microorganisms. When swimming, these pathogens can easily enter the uterine cavity through the vagina, potentially causing infectious conditions such as vaginitis, cervicitis, or pelvic inflammatory disease.

In addition, the body's immunity is generally weaker during menstruation. Exposure to cold water may cause constriction of blood vessels in the pelvic region, leading to worsened menstrual cramps, reduced menstrual flow, or poor discharge of menstrual blood. Even when using tampons, they cannot completely prevent pool water from entering the body. Moreover, prolonged soaking reduces the absorbency of tampons and may increase the risk of infection due to a damp local environment.

To avoid infections and discomfort during menstruation, it is advisable to wait until menstruation has completely ended and the body has returned to normal before swimming. During this time, gentle exercises such as walking or yoga are good alternatives—they allow physical activity without negatively affecting menstrual health. The choice of exercise should be based on individual physical comfort and symptoms.

Under normal circumstances, the term "below" refers to the perineum.

Can I receive breast massage for enhancement during my menstrual period?

In general, breast massage for the purpose of breast enhancement should be avoided during menstruation. A safer approach is to schedule breast care 3–5 days after the menstrual period ends, when hormone levels have declined, breast tenderness has subsided, and breast tissue is most receptive. Daily maintenance should focus on wearing well-fitted bras, maintaining a balanced diet, and engaging in regular exercise. If persistent breast asymmetry occurs, a consultation with a breast specialty clinic is recommended for evaluation.
