Menstruation, often referred to as menses or a period, involves the monthly discharge of blood and mucosal tissue from the uterus through the vagina, typically beginning between the ages of 12 and 15, known as menarche. The menstrual cycle lasts 21-45 days in young women, averaging 28 days in adults, with bleeding lasting 2 to 7 days. Feminine hygiene products, essential for managing menstruation, include disposable items like sanitary napkins and tampons, as well as reusable options such as menstrual cups and cloth pads. Menstrual cups, made from silicone, are eco-friendly and cost-effective but face adoption barriers due to lack of awareness. This study aimed to assess knowledge about the side effects of sanitary pads and promote menstrual cup usage among college girls. Utilizing a non-experimental survey design, data was collected over seven days from 30 respondents using a structured questionnaire. Results indicated that a significant majority (90%) of participants had inadequate knowledge regarding menstrual cups, with only 10% exhibiting moderate knowledge. The findings highlight a critical gap in awareness about menstrual health and hygiene, emphasizing the need for educational interventions. Promoting knowledge about menstrual cups could encourage better practices and hygiene management during menstruation. Further research is necessary to explore effective strategies for increasing awareness and acceptance of menstrual cups among young women.
