Women can drink more water or pay attention to keep warm so that the menstrual blood can flow smoothly, and it will change from purple to dark red. During menstruation, women’s bodies are weaker due to the decline in hormone levels, and they are also prone to menstrual cramps. Women should pay attention to proper rest during this period, eat more hot and nutritious food, drink brown sugar water, and avoid overwork and cold to facilitate the smooth discharge of menstrual blood. The occasional purple menstruation of women does not affect the health of the body, but if there is often purple menstrual blood, you should also pay attention to the hospital to do gynecological ultrasound to see if there is a cavity lesion.
