Does alcohol consumption and smoking affect menstrual pain?
In general, menstrual pain refers to dysmenorrhea. Alcohol consumption and smoking can have certain effects on dysmenorrhea, although the extent of influence varies among individuals. A detailed analysis is as follows:

Alcohol is a stimulant beverage, and cigarettes contain stimulant substances. Drinking alcohol or smoking during menstruation may stimulate the uterus, causing excessive uterine contractions, thereby inducing abdominal pain or exacerbating its severity. Additionally, the combination of alcohol and cigarettes may indirectly affect estrogen levels, potentially altering menstrual flow and cycle regularity, manifesting as reduced menstrual volume, delayed or earlier periods. Therefore, smoking or drinking alcohol during menstruation can affect dysmenorrhea. However, due to individual differences and varying absorption rates, the extent of impact on menstruation also varies.
For health considerations, alcohol consumption and smoking are not recommended during menstruation. Additionally, a healthy lifestyle should be maintained during this period, avoiding late nights and excessive fatigue.
