In Jain tradition, menstruation (ritu‑dharma) is a natural process. Kitchen rules are based on maryada (family/sangh customs), not a direct Agamic command. Common practice is:

• Shwetambar maryada: Do not cook or handle the kitchen during the days of flow. After the flow stops, on the 4th day take a full snan (bath with hair wash), wear freshly washed clothes, change bed/cloths, and then you may enter and use the kitchen.
• Digambar maryada (in many families): Observe one more day. After completing 4 days, on the 5th day, take full snan and then enter the kitchen.
• If bleeding continues beyond day 3/4, wait until it fully stops; then do the full snan the next morning and resume kitchen work as per your family’s maryada.

Simple hygiene steps before re‑entry:

• Full bath with hair wash; wear washed clothes.
• Wash hands thoroughly; clean kitchen surfaces and frequently used utensils.
• Keep drinking water filtered/covered as per Jain shuddhi.

These practices vary by locality and guru‑maryada. Follow the guidance of your family/sangh.
