You can enjoy Diwali while pregnant. The main things to plan around are cracker smoke, milk sweets that may not be fresh, big swings in blood sugar, loud bursts close by, and getting too tired. Stay indoors when the crackers start, eat sweets in small portions from a trusted source, skip alcohol completely, and know the warning signs that mean you should call your doctor or go to hospital that night, festival or not.
Why cracker smoke matters more in pregnancy
Fine particles (PM2.5) in polluted air are linked with babies being born smaller or earlier. A large 2021 analysis in PLOS Medicine pooled studies from many countries and found that for every 10 µg/m³ rise in long-term outdoor PM2.5, birth weight was about 22 g lower, the risk of low birth weight was 11% higher, and the risk of preterm birth was 12% higher.
Two things to keep in mind. These are associations from exposure over weeks and months, not proof that one smoky night will harm your baby. And most of the studies came from North America, Europe and Australia, with only a few from India. So there’s no reason to panic about Diwali, but there’s every reason to keep your own exposure low, especially in a season when the air in many Indian cities is already poor.
How to cut your smoke exposure
- Stay indoors from dusk on Diwali night, when most crackers are burst, and keep windows on the street side shut until the next morning.
- Watch from a window, not the street. Let others light the crackers. Sparklers and anar give off a lot of smoke right at face level.
- Make one room your clean-air room. If you have an air purifier, run it in the bedroom with the door closed and sleep there.
- Wear a well-fitting N95 if you must go out. Pick one that seals around the nose and chin. If it makes you feel breathless, take it off and go indoors, and mention it to your doctor.
- Limit indoor smoke too. Light one agarbatti or dhoop for puja, away from where you sit, and keep the kitchen exhaust on while frying.
- Stay away from cigarette smoke, including guests smoking on the balcony.
If you have asthma, see our Diwali asthma checklist as well. Keep taking your inhalers as prescribed during pregnancy unless your doctor changes them.
Sweets and gestational diabetes
Gestational diabetes is high blood sugar that develops during pregnancy and usually goes away after birth. The NHS explains that it can lead to the baby growing larger than usual, which can make delivery harder, and is linked to premature birth and to low blood sugar or jaundice in the baby after birth.
If you’ve been diagnosed with gestational diabetes, follow the diet plan your doctor or dietitian gave you over the festival. A few practical ideas:
- Choose one small piece of a sweet you really want, rather than tasting everything on the plate.
- Have it after a meal with protein and fibre (dal, curd, sabzi), not on an empty stomach or as a late-night snack.
- Go easy on sweetened drinks, sharbat and packaged juice, which raise sugar fast.
- Check your sugar at the times you’ve been told to, and note what you ate if a reading is high.
- If you’re on insulin or tablets, don’t change the dose yourself to “make room” for sweets.
Our Diwali sweets portion guide for diabetes gives rough sizes for common mithai. If you’re unsure which sugar test applies to you, our explainer on HbA1c vs fasting blood sugar notes that HbA1c isn’t used to diagnose gestational diabetes; glucose tests are used instead.
Food safety: milk sweets, paneer and leftovers
The main worry is Listeria, a bacterium that can contaminate unpasteurised and soft dairy foods. The US CDC says pregnant women are 10 times more likely to get a Listeria infection. The NHS warns that listeriosis can cause miscarriage or stillbirth, or make a newborn very unwell.
- Paneer is fine if it’s made from pasteurised milk. The NHS lists pasteurised paneer as safe. If you don’t know how the milk was handled, eat paneer cooked until steaming hot rather than raw or in a cold salad.
- Avoid unpasteurised (raw) milk and anything made from it. Both the NHS and CDC advise against raw milk dairy in pregnancy.
- Buy milk sweets fresh, from a busy, clean shop. Prefer sweets made the same day, check the best-before date on the tray, and refrigerate them at home.
- Don’t eat sweets that have sat out for hours at a party or puja, especially ones with khoya, chhena, cream or malai.
- Heat leftovers until steaming hot all the way through.
- Wash fruit and salad vegetables well before eating.
Alcohol and caffeine. The NHS says it’s safest to avoid alcohol completely in pregnancy, as it can cause long-term harm to the baby. Keep caffeine to no more than 200 mg a day, and remember that tea, coffee and cola all count.
Fasting on Diwali when you’re pregnant
Some families fast on Diwali or for Lakshmi puja. Talk to your doctor before fasting during pregnancy, especially if you have gestational diabetes, take insulin, have had low blood pressure or fainting, or are in the third trimester. If you do keep a modified fast, keep drinking water, eat something light at regular intervals, and break the fast if you feel dizzy, shaky, faint or notice your baby moving less.
Loud crackers, stress and sleep
The US workplace-safety agency NIOSH says very loud noises may be able to damage a developing baby’s hearing. Its key points:
- A baby’s ears develop by about week 20, and babies start responding to sound around week 24.
- Sound is quieter inside the womb but not blocked.
- Some experts advise that pregnant women shouldn’t routinely be around noise louder than 115 dBA.
- Earplugs protect your ears but won’t fully protect the baby’s.
- Low, rumbling sounds you feel in your body travel more easily. Move away from the source and don’t lean against walls or railings that vibrate.
In practice: stay indoors, away from the street side of the house, while big bombs and garlands of crackers are going off. Our article on firecracker noise and hearing covers how loud crackers get and how to protect the rest of the family.
Noise late into the night also means poor sleep and more stress for you. Plan a nap in the afternoon, eat dinner early, and go to bed in the quietest room. If festival pressure, family expectations or worries about the pregnancy feel overwhelming, talk to someone. Tele-MANAS, the government mental health helpline, is free on 14416.
Burns: keep your distance
A pregnant belly changes your balance and makes it harder to step back quickly. Don’t light crackers yourself or bend over diyas and rangoli lamps. Wear cotton, and keep loose dupattas, saree pallus and long sleeves well away from flames. Keep a bucket of water nearby. If a burn does happen, our Diwali burns first aid guide explains cooling the burn with running water and when to go to hospital. A burn about the size of your palm (with fingers) or larger, or one on the face or hands, needs a doctor the same day.
Go to hospital or call your doctor straight away if…
Don’t wait until after the festival for any of these. Call your doctor or maternity unit, go to the hospital where you’re booked, or call 112 if you can’t get there.
- Vaginal bleeding of any amount.
- Your baby is moving less than usual, has stopped moving, or the pattern has changed. The NHS says to call straight away and not wait until the next day, even at night.
- A severe headache that doesn’t go away with simple painkillers, vision problems (blurring or flashing lights), pain below the ribs, vomiting, or sudden swelling of the face, hands or feet. These can be signs of pre-eclampsia.
- A gush or trickle of fluid from the vagina.
- Before 37 weeks: regular tightenings or contractions, period-type pains, or backache that isn’t usual for you, which the NHS lists as possible signs of premature labour.
- Fever or chills, or severe pain in your tummy.
- Breathlessness that’s getting worse, chest pain, or an asthma attack that isn’t settling with your inhaler.
- A burn about the size of your palm or larger, or a fall or blow to the bump.
Frequently asked questions
Can firecracker smoke on one night harm my baby?
The research links longer-term exposure over weeks and months with lower birth weight and preterm birth. One night isn’t known to cause harm, but it’s sensible to stay indoors and keep the smoke out.
Can I eat Diwali sweets while pregnant?
Yes, in small amounts, if they’re fresh and from a clean shop. If you have gestational diabetes, follow your diet plan and keep to one small piece after a meal.
Is paneer safe in pregnancy?
Paneer made from pasteurised milk is considered safe. If you’re unsure of the milk, eat paneer only when it’s cooked until steaming hot.
Can loud crackers make my baby jump or kick?
Babies respond to sound from about 24 weeks, so you may feel movement. Move to a quieter room. If your baby’s movements reduce afterwards, call your maternity unit.
Is a small drink at a Diwali party okay?
No. The NHS says the safest approach in pregnancy is to avoid alcohol completely. Ask for a mocktail or nimbu pani instead.
