Is it better for menstruation to come early or late?

In general, there is no absolute good or bad when a menstrual period arrives earlier or later than expected. The key factor is whether the menstrual cycle remains consistently regular over time and whether fluctuations fall within the normal range. If the period occurs within seven days earlier or later than expected and the cycle remains stable, there is typically no need for excessive concern. However, if the deviation exceeds this range or the cycle frequently changes, it may indicate an abnormal physical condition. Detailed explanations are as follows:

If the menstrual period occasionally comes earlier, by less than seven days, this is often related to emotional fluctuations, recent stress, changes in sleep patterns, or dietary adjustments. In such cases, menstrual flow and duration typically remain unchanged. Once lifestyle adjustments are made, the cycle usually returns to normal without significantly affecting health.

When the menstrual period occasionally occurs later, by less than seven days, it may be caused by recent excessive fatigue, environmental changes, or emotional anxiety. As long as the menstrual flow is normal, there is no significant discomfort during the period, and the cycle subsequently stabilizes, this is generally considered a normal physiological fluctuation and does not require special treatment.

To maintain a stable menstrual cycle, it is recommended to maintain a regular sleep-wake schedule in daily life and avoid chronic late-night hours. Nutritionally, a balanced diet with reduced intake of raw, cold, or overly spicy foods is advised.
