Climate change is having a devastating impact on menstrual health and hygiene around the world, particularly for women and girls who menstruate. Research has shown that extreme weather events like floods and cyclones can destroy water and sanitation systems, leaving people without access to basic necessities like clean water and safe places to use sanitary products. This can lead to uncomfortable and unsanitary conditions, as well as increased risk of infections and other health problems. Droughts and saltwater intrusion also pose significant challenges, reducing the availability of clean water and making hygiene practices difficult or impossible. The consequences are not just physical, but also emotional and social, with many people facing stigma and restricted mobility due to their menstrual needs.
