It is normal to be sleepy during menstruation. Many women experience discomfort during menstruation due to changes in hormone levels and pelvic congestion, and some women do not have a good appetite during this time, and are particularly tired and sleepy. This condition is more obvious on the 1st and 2nd days of menstruation, when the volume of menstruation is the highest, and the symptoms will gradually improve on the 3rd and 4th days. Therefore, during menstruation, it is recommended to take a good rest, do not work too hard, eat a lighter diet, drink brown sugar water during menstruation to relieve menstrual pain and discomfort, and get enough sleep.
