It is best for women not to drink tea during menstruation for the following reasons: First, because tea contains more tannic acid, which will affect the absorption of iron. Secondly, drinking tea will lead to insomnia due to nervous system excitement, thus affecting women’s health. Women should pay attention to rest during menstruation, and eat more easily digestible and blood-supplementing foods in the diet, such as dates, millet porridge, red bean porridge, milk, which is beneficial to the supplementation of nutrients, thus reducing anemia. During menstruation, women will lose their appetite due to the decrease of hormone level in the body, which will easily lead to fatigue, weakness and cold, thus reducing the body’s resistance and immunity. During this period, you should pay attention to keep warm and increase nutrition appropriately to facilitate the smooth discharge of menstrual blood and body recovery.
