Chhath Festival Begins: Understanding the Physiological Effects of Fasting
Summary
Chhath Puja begins with Nahay-Khay in Kathmandu as devotees prepare for a 36-hour Nirjala fast without food or water. The article explains how fasting affects glycogen use, dehydration, kidney function, and the heart, and urges people with chronic illnesses to seek medical advice.
Key Points
- Chhath Puja begins with Nahay-Khay on Friday as part of the six-day Diwali festival.
- Devotees observe a Nirjala fast for about 36 hours, going without food and water until offering Arghya to the rising sun.
- The body first uses stored glycogen, then shifts to fat and ketone production for energy during prolonged fasting.
- Dehydration can reduce blood volume, affect the heart and brain, and disrupt sodium and potassium balance, raising health risks.
