There is an old wives’ tale that washing up on your period can cause complications. However, there is no truth behind this myth at all! It is perfectly alright to wash up during your periods. A hot shower during your period can be wonderful to alleviate the horrible menstrual cramps, and it can help you feel clean and fresh during those days.
You can also have a soothing warm bath, and contrary to the old myth, it's actually beneficial for your health. The hot water helps increase blood supply to the uterus and releases relaxing hormones in the body that reduce cramps and may even reduce blood outflow!
It is a good hygiene practice to clean yourselves during periods, so there's no reason for you to stay away from the shower or bath!
