Change the menstrual towel frequently and pay attention to cleanliness. Girls should not use detergent. Be sure to pay attention Remember to clean it with boiling water cooled to a suitable temperature. Don't use raw water. There are too many bacteria in it. Towels should also be disinfected. And underwear that needs ventilation. I don't need to remind you that you should get enough sleep, eat healthy food, and don't eat cold food! I wish you all a happy collective life!
