Introduction
Bright red menstrual blood is normal. Menstrual fluid primarily consists of blood, fragments of endometrial tissue, and various active enzymes and biological factors.

The average menstrual blood volume ranges from 30 to 80 mL, and the typical duration of menstruation is 3–7 days. In cases of menstrual irregularity, the most common underlying cause is chronic lifestyle disruption. It is recommended to maintain healthy daily habits—avoiding late-night activities and excessive physical or mental fatigue—as this often leads to significant improvement or resolution of menstrual irregularities.
During menstruation, pay close attention to personal hygiene and keep the abdomen warm. Consume warm, nourishing foods and avoid raw, cold, spicy, or otherwise irritating foods. Should you experience unusual symptoms, marked discomfort, abnormally heavy or light menstrual flow, or any other concerning changes during your period, seek prompt medical evaluation at a healthcare facility.
