Does washing your hair during menstruation cause uterine cancer? Is there a direct link between washing hair during menstruation and cancer?
Folk belief:
During menstruation, one should avoid washing hair or consuming cold foods to prevent residual blood from accumulating in the uterus. Over time, this may disrupt hormone balance and lead to breast or uterine cancer.
Medical clarification:
False. Hormonal (endocrine) imbalances stem from physiological, psychological, environmental, and genetic factors—not menstrual practices. Cancer development relates to lifestyle and environmental exposure. Neglecting hygiene during menstruation may cause blood stagnation, potentially triggering pathological changes over time, though not necessarily cancerous ones.
Valid Point: Avoiding Cold Foods During Menstruation
During menstruation, women experience reduced immunity. Exposure to cold can cause stagnation of qi and blood, potentially leading to menstrual irregularities or dysmenorrhea. Therefore, it is advisable to avoid drafts, cold weather, rain, wading in water, cold foot baths, or cold showers, and to refrain from consuming raw or cold foods. These precautions are reasonable. However, bathing or washing hair with warm water poses no health risks.
