Chhath Puja involves large gatherings at riverbanks, ponds, and designated Chhath ghats, which may lead to overcrowding and potential safety risks. The festival's emphasis on cleanliness and water-based rituals could pose challenges in areas with water pollution or limited access to clean water. Additionally, the strict fasting observed by devotees may lead to health concerns, particularly for those with pre-existing conditions. Authorities may need to ensure proper crowd management and water quality during the festival.
