Karwa Chauth and Periods: Should You Fast or Skip It? Expert Weighs In

Karwa Chauth is one of the most cherished festivals in India, celebrated with love and devotion by married women who fast from sunrise to moonrise for their husbands’ long life. Many women enjoy dressing up, applying mehendi, and performing rituals with great faith. But what happens when Karwa Chauth falls on a day when a woman is on her period? Is it safe to fast, or should she skip it? To answer this, we spoke to Dr Chetna Jain, Director, Department of Obstetrics & Gynaecology, Cloudnine Group of Hospitals, Gurgaon, who shared valuable guidance on this personal and often misunderstood topic.

Can You Fast Safely During Periods?

Dr Jain says it depends entirely on how you feel physically. “Women who are feeling this more often should not put their health at risk for a tradition. But if they are comfortable, they can probably take sargi in the morning at four o'clock, then keep hydrated through the day by taking fruit juices, milk, or water.”

She explains that the focus should be on the intention and devotion, not just the act of fasting. “It is more important to be fasting and giving love and affection from the mind, keeping the faith, doing rituals and pujas, dressing up even without fasting.”

• Fasting without water, especially during menstruation, can take a toll on your health.
• It may cause cramps, weakness, or dizziness
• Dehydration can make period symptoms worse
• Skipping meals may affect blood sugar levels, especially in women with anaemia or low blood pressure

Periods and Karwa Chauth: Belief Versus Biology

Dr Jain begins: “Karwa Chauth is a very personal belief, and periods should not interfere with your feelings of fasting or not fasting. It’s more than a ritual and it’s about love, faith, and commitment.” She describes fond memories of her own mother, dressed in red and waiting for the moon while quietly praying for her husband.

For many women, the strength behind the tradition outweighs physical discomfort. However, traditional beliefs in some families still label periods as "impure," with instructions not to touch puja items or enter temples. Dr Jain encourages us to pause and reflect, “Is it truly unclean, or just misunderstood?”

What Your Body Needs During Periods

Medical science looks at menstruation as a natural process, not something dirty. “During periods, the uterus sheds its old lining and prepares for a new one. This is when a woman needs rest, nourishment, and hydration,” explains Dr Jain. Fasting without water, as is traditional in Karwa Chauth, can increase risks of:

• Cramps and stomach pain
• Weakness and dizziness
• Fainting and dehydration
• Women with heavier cycles or severe symptoms may feel these effects more acutely.

Tips for Fasting (If You Decide To)

If a woman chooses to fast while on her period, Dr Jain advises being aware of the body’s needs. “Have sargi in the morning. Keep up hydration with water, fruit juices, or milk—don’t hesitate to eat fruits throughout the day if you feel weak. It’s vital not to put health at risk for tradition.”

Key tips:

• Prioritise hydration: Sip water or natural juices when possible
• Eat light, nourishing foods if feeling faint
• Take breaks and rest when needed
• Dress comfortably and listen to your body

When It’s Okay to Skip the Fast

Dr Jain emphasises, “It’s more important to express love and affection from the heart. Participating in rituals, dressing up, and being a part of the celebrations can carry just as much devotion as fasting itself.” Women who feel unwell should never force themselves to fast. “Rest, nourish your body, and don’t let guilt ruin your joy,” she adds.

Medical studies support the importance of hydration and nutrition during menstruation. According to a study in the Journal of Obstetrics and Gynaecology Research, dehydration and fasting during periods can worsen cramps, fatigue, and concentration problems, leading to greater discomfort and health risks. The study encourages women to prioritise well-being and rest during their menstrual cycle.

Conclusion

Karwa Chauth’s spirit lies in love and intention, not just in following food restrictions. Dr Jain summarises, “Whether you fast or not depends entirely on you and your body. Respect your feelings, health, and needs.” However, if you feel weak or uncomfortable, it’s okay to honour the tradition in your own way through prayers, rituals, and the spirit of devotion. Ultimately, fasting or not fasting doesn’t define your faith, but your intention does.
