Diwali is happening across India, and while homes shine with lights and sweets fill the markets, preparations for Chhath Puja 2025 are quietly beginning. This four-day festival, observed from 25 to 28 October, is celebrated mainly in Bihar, Jharkhand, eastern Uttar Pradesh, and parts of Nepal. Devotees honour the Sun God and Chhathi Maiya through prayers, rituals, and the 36-hour nirjala fast, during which they avoid both food and water. This fast is a test of patience, devotion, and discipline, but it also affects the body in several ways.
How 36-Hour Fast Impacts the Body
During the Chhath Puja 2025 nirjala fast, the digestive system slows, giving the organs a much-needed rest and aiding natural detoxification. Dr Sonia Rawat from Sir Ganga Ram Hospital notes that fasting can calm the mind, lower stress, and redirect the body’s energy from digestion to essential metabolic processes. While these changes can be beneficial, the intensity of a full 36-hour waterless fast means proper planning and attention to physical readiness are crucial.
Safety Tips
The biggest concern during a nirjala fast is dehydration. Without water, symptoms such as dizziness, headaches, fatigue, and electrolyte imbalances can appear. Experts recommend increasing water intake several days before the fast and consulting a doctor if you have conditions like diabetes, heart disease, kidney issues, or blood pressure concerns. With the right preparation, devotees can safely complete the Chhath Puja 2025 fast while enjoying its spiritual, mental, and health benefits.
