While scientific evidence doesn’t point towards any harmful effects of Lunar Eclipse or Chandra Grahan, you can choose to follow your own traditions

As per science, you can safely sleep during a Chandra Grahan, or lunar eclipse, without any health risks tied to myths. Some traditions reportedly advise against it due to beliefs about toxic lunar rays or pollution (dosha), but science debunks these concerns.

A lunar eclipse happens when Earth shadows the Moon, dimming it briefly—typically 1-3 hours. NASA and ISRO confirm no harmful radiation reaches Earth; it’s just reflected sunlight blocked. Studies have not shown a spike in ailments like miscarriages or digestive issues during eclipses. Sleep remains unaffected—your body follows its circadian rhythm, not lunar phases.
Cultural Beliefs
In India, Chandra Grahan makes people practise myriad rituals: staying awake (jaagran), chanting mantras, or fasting. Many texts warn of “poisonous rays” harming the vulnerable, especially pregnant women or infants. Much of this information is not grounded in scientific reason. Earlier, eclipses were seen as mysterious events, which could bring bad luck to people and cause deformities in unborn children. While details differ by region, some commonly shared beliefs include:
Pregnant women should stay indoors during an eclipse.
Eating or drinking during the eclipse is discouraged.
Using knives, scissors or needles is considered risky.
Sleeping during an eclipse is avoided.
Looking at the eclipse is believed to cause birth defects.
Some believe exposure may lead to miscarriage or complications.
What Science Actually Says
Modern medical science has found no evidence that an eclipse directly harms pregnant women or unborn babies.
Here’s what research and health experts generally agree on:
There is no scientifically proven mechanism linking eclipses to fetal development, miscarriage or physical deformities. The alignment of celestial bodies does not emit harmful radiation or energy capable of affecting pregnancy. The baby is well protected inside a woman’s womb.
However, if you do believe in certain religious traditions, you can choose to follow them accordingly.
Dos and Don’ts For Pregnant Women As Per Beliefs
Many traditional beliefs suggest that pregnant women should take extra care during a lunar eclipse (Chandra Grahan). Here are some commonly followed precautions:
- Stay indoors: Pregnant women are advised to remain inside the house during the eclipse to protect themselves and their unborn baby.

- Avoid heavy work: Expecting mothers should not do physical or strenuous work during the eclipse period. It is recommended to rest.
- Take a bath after the eclipse: After the eclipse ends, pregnant women are advised to take a bath. Some traditions suggest adding a few drops of Gangajal (holy water) to the bath water. If Gangajal is not available, adding rock salt to the water is considered an alternative.
- Sit peacefully and pray: During the eclipse, pregnant women are advised to sit in a calm and quiet place, or sit comfortably on the bed in a relaxed posture (like Sukhasana). Some traditions suggest keeping a coconut filled with water in their lap while chanting mantras, meditating, or reading religious texts.
- Do not sleep during the eclipse: Sleeping during the eclipse is considered inauspicious according to traditional beliefs.
