This year Karwa Chauth will be observed on October 13. This is the time of year when married women fast from morning to night, offering their prayers to the lord moon for their husbands' longevity, prosperity and health. On the other hand, fasting can have its drawbacks. When we fast for an extended period, our bodies experience numerous complications. While women usually follow the rituals and traditions of the day, it is recommended that they modify the rituals slightly to ensure their health is not affected.
