Introduction
Bright red menstrual blood is normal. Menstrual fluid primarily consists of blood, fragments of endometrial tissue, and various active enzymes and biological factors. Under normal circumstances, menstrual blood appears bright red or dark red and may contain small blood clots—this is considered normal menstruation. Typically, total menstrual blood loss ranges from 30 to 80 mL, and the normal duration of menstruation is 3 to 7 days.

Typically, menstrual blood loss ranges from 30 to 80 mL, and the duration of menstruation normally lasts 3–7 days. In cases of menstrual irregularities, most instances are attributed to prolonged lifestyle imbalances. It is recommended to maintain healthy daily habits—avoid staying up late and excessive physical exertion—as these measures often lead to significant relief and improvement of menstrual irregularities.
During menstruation, it is advisable to maintain good personal hygiene and keep the abdomen warm. Consume warm, nourishing foods and avoid raw, cold, spicy, or otherwise irritating foods. Should any abnormal symptoms or marked discomfort arise during menstruation—or if menstrual flow significantly increases or decreases—it is essential to seek timely medical evaluation at a hospital.
