Prepping for climate resilience while pregnant

In short: Pregnant women feel the heat more and lose water faster, so heatwaves, polluted air and unsafe water need extra care. Stay indoors in the hottest hours, drink water through the day, wear loose cotton clothes, check the air quality before going out, and drink only boiled or filtered water. If you feel confused, faint or very hot, or your baby is moving less than usual, go to a hospital straight away.

Becoming a mother is a beautiful journey, but navigating pregnancy in today’s climate-challenged world brings a new layer of complexity. With rising temperatures, poor air quality, and unpredictable water safety, expecting mothers now face environmental threats that can directly impact their health and their baby’s development.

In this guide, we break down how you can stay safe and build resilience during pregnancy, even as the climate around us changes.

Why climate resilience matters in pregnancy

Pregnancy is a time when your body is already working overtime. Add a heatwave, smoky skies, or contaminated water, and your stress levels and risks can soar. Exposure to extreme heat, air pollution, and waterborne toxins during pregnancy can increase the risk of complications like:

• Preterm labor
• Low birth weight
• Gestational hypertension or preeclampsia
• Increased respiratory issues in newborns

Preparing for climate resilience during pregnancy is not just smart, it is essential.

1. Heatwaves: Staying cool, safe & hydrated

Why is it dangerous?

Pregnant women are more prone to heat stress because their body temperature is naturally higher. Extreme heat can lead to dehydration, heat exhaustion, or even preterm labor.

What you can do:

• Stay indoors during peak heat (11 AM – 4 PM) Use fans, air conditioning, or cooling cloths to regulate body temperature.
• Hydrate like it is your job Aim for 10–12 glasses of water daily. Add electrolytes or coconut water if you are sweating more than usual.
• Dress in breathable, light fabrics Cotton, linen, and loose-fitting clothes can make a big difference.
• Take short, cool showers to lower your core temperature.

Pro Tip_:_ If your area experiences frequent heat waves, consider creating a “cool corner” in your home with blackout curtains, a standing fan, and chilled water bottles.

2. Air pollution: Protecting your lungs & your baby’s development

Why is it dangerous?

Air pollution, especially fine particulate matter (PM2.5), can cross the placenta and affect fetal development. Pollution spikes during wildfires, industrial emissions, or heavy traffic days can increase the risk of asthma and neurodevelopmental issues in babies.

What you can do:

• Track your local Air Quality Index (AQI) Install apps like AQI India, SAFAR-Air, or Plume Labs to stay informed.
• Stay indoors on poor air days, especially during peak pollution hours (early morning or late evening).
• Use a HEPA air purifier in your bedroom or living space.
• Wear an N95 mask when stepping outside is unavoidable.
• Keep houseplants like snake plant or areca palm to mildly improve indoor air quality (note: not a substitute for purifiers).

Pro Tip_:_ Avoid high-traffic roads during your walks and opt for green parks or indoor malls on poor AQI days.

3. Water safety: What is in your glass can matter more than you think

Why is it dangerous?

Contaminated or unsafe water can carry bacteria, viruses, and heavy metals that harm both mother and baby. During floods or water cuts, these risks spike drastically.

What you can do:

• Drink filtered or boiled water, always. Install a reliable water purifier with RO + UV + UF filters if possible.
• Avoid drinking water from outdoor sources, especially after floods or during monsoon.
• Store safe drinking water during unpredictable weather in clean, covered containers.
• Wash fruits and vegetables with clean water, and avoid street food.

Pro Tip_:_ If you live in an area with water issues, consider regular testing of your home water supply or use a water test kit.

Additional tips for building climate resilience while pregnant

• Stock up on essentials during weather alerts: Electrolytes, ORS packets, pregnancy-safe snacks, and cooling aids.
• Talk to your OB-GYN about any new symptoms after exposure to poor air or heat.
• Build a support system, keep family, neighbours, or doulas informed so they can help in emergencies.
• Include climate-safe planning in your birth prep, especially if you are due in peak summer or monsoon.

Pregnancy in a climate-uncertain world is not easy, but you are not powerless. By staying informed and making small but strategic choices, you can shield both yourself and your growing baby from the worst impacts of heat, pollution, and unsafe water.

Questions women ask

What are the symptoms of heat stroke in pregnancy?

Watch for a very high body temperature, hot dry or flushed skin, confusion, a fast heartbeat, severe headache, vomiting or fainting. This is an emergency. Move to a cool place, sponge your body with water and go to a hospital straight away.

How can I stay cool in pregnancy during summer?

Stay indoors during the hottest part of the day, keep sipping water, and add coconut water, nimbu pani with a pinch of salt, or buttermilk if you are sweating a lot. Wear loose cotton or linen, take cool showers, and keep one room as cool as you can with fans, curtains and cold water.

Is poor air quality harmful in pregnancy?

Polluted air can affect your breathing and, over time, your baby's growth. On high AQI days stay indoors, keep windows shut during peak pollution, use an air purifier if you can, and wear a well-fitting N95 mask if you must go out. Walk in parks rather than near busy roads.

What is heat exhaustion in pregnancy and what should I do?

Heat exhaustion comes before heat stroke. You may feel very tired, dizzy, sweaty, thirsty or sick, with cramps or a headache. Rest in a cool place, drink water and loosen your clothes. If you do not feel better within 30 minutes, or you feel worse, go to a hospital straight away.

When should I see a doctor after heat or pollution exposure?

Go to hospital straight away if you feel confused or faint, notice your baby moving less, or get breathlessness, chest pain, bleeding, leaking fluid or tightening of the tummy. See a doctor the same day if you have a fever or cannot keep water down. For new coughs or wheezing after poor air days, talk to your gynaecologist.
