The Do's and Don'ts of Summer Activities and Travel During Pregnancy

If I’m pregnant in summer, my top job is simple: stay cool, drink enough, and avoid stuff that can overheat me or increase fall and travel risks. For most people, that means 64–96 oz of water a day, outdoor time before 10 a.m. or after 4 p.m., SPF 30+, and no hot tubs, saunas, scuba diving, or high-impact rides.

Here’s the short version:

• Do plan around heat and humidity.
• Do choose low-impact activity like walking, swimming, prenatal yoga, and indoor exercise.
• Do use shade, breathable clothes, and cooling breaks every 1–2 hours.
• Do travel with extra planning, especially in the third trimester.
• Don’t ignore dizziness, contractions, bleeding, fluid leakage, chest pain, or less fetal movement.
• Don’t sit too long on road trips or flights; move often to lower DVT risk.
• Don’t count on summer outings if you’re close to delivery or have a high-risk pregnancy without checking with your OB-GYN.

Bottom line: the second trimester (weeks 14–27) is often the easiest time for trips, while the third trimester (weeks 28 to delivery) usually calls for shorter plans, more breaks, and staying closer to care. If heat symptoms don’t improve after rest and fluids - or if you have signs like fainting, trouble breathing, painful cramping, one-sided leg swelling, or vaginal bleeding - it’s time to call your provider, and for heat stroke signs, call 911.

If I were making summer plans while pregnant, I’d use this as a fast checklist for heat, hydration, swimming, beach days, road trips, flights, and warning signs before I leave home.

Summer Safety Basics During Pregnancy

Pregnancy can make summer heat hit harder. You may overheat faster, lose fluids more easily, and feel the sun more than usual. So the starting point is simple: keep cool, drink often, and protect your skin.

Do: Stay Cool, Hydrated, and Protected from the Sun

The American College of Obstetricians and Gynecologists (ACOG) recommends 8 to 12 cups (64–96 oz) of water daily during pregnancy. In hot weather, start early. Don't wait until you're thirsty. A refillable water bottle makes this much easier when you're out and about.

Plain water is a great place to start, but it's not your only option. Low-sugar electrolyte drinks and water-rich foods like watermelon, cucumbers, and celery can help too. One easy check is urine color: pale yellow means you're doing okay; dark yellow usually means you need more fluids.

Try to plan outdoor time before 10 a.m. or after 4 p.m., when the heat is less intense. Wear loose, breathable clothes, and use broad-spectrum SPF 30+ sunscreen. Reapply every 2 hours, or right after swimming or heavy sweating. Mineral-based sunscreens with zinc oxide or titanium dioxide are a solid pick during pregnancy. If you're outside for a while, take regular breaks in air-conditioned spaces.

Don't: Ignore Heat Exposure and Overheating Risks

Hot tubs, saunas, and very hot baths can push your core body temperature above 102.2°F. That can trigger cramping or contractions. Tanning beds bring the same heat concern and add UV exposure you don't need.

It's also a bad idea to drink less just to avoid bathroom stops during errands or travel. Low fluid levels can trigger contractions, which can feel scary and may look like preterm labor signs and symptoms at first.

Stop and Call Your Provider If Heat Symptoms Do Not Improve

If you cool down and drink fluids but still don't feel better, contact your provider. Reach out right away if you have:

• Persistent dizziness, lightheadedness, or fainting
• Trouble breathing that doesn't improve with rest
• Chest pain or a racing heartbeat
• Decreased fetal movement
• Painful cramping or contractions
• Vaginal bleeding or fluid leakage
• Severe swelling of the hands or face

The table below shows the difference between dehydration, heat exhaustion, and heat stroke.

Condition	Skin Symptoms	Pulse/Heart Rate	Mental/Neurological Signs
Dehydration	Dry mouth, dry lips	Rapid	Dizziness, headache
Heat Exhaustion	Cold, clammy skin	Fast, weak	Nausea, dizziness, fainting
Heat Stroke	Hot, red, dry or damp skin	Fast, strong	Confusion or collapse

Heat stroke, marked by a body temperature of 102.2°F or higher, is a medical emergency. Call 911 right away if you or someone with you shows those signs.

With heat under control, the next checklist covers low-impact exercise, swimming, and beach safety.

Exercise, Swimming, and Beach Day Do's and Don'ts

Once you've got the heat under control, you can still stay active and enjoy summer. The key is picking the right activity, at the right time, and knowing when to scale things back.

Walking, Stretching, and Other Low-Impact Exercise

For outdoor walks, flat and shaded routes are your safest bet. Go in the early morning or late evening, when the heat isn't at its worst. Wear supportive shoes or sandals to help cut down on foot pain and lower the chance of a fall. And bring water. It helps to take breaks before you feel worn out.

If it's too hot outside, move your workout indoors. Prenatal care and exercise options like yoga, gentle stretching, and stationary cycling are all good choices. Indoor mall walking also works well when you want an air-conditioned place to keep moving.

Some activities are best left off the list during pregnancy, especially in summer heat. Skip contact sports, high-fall-risk activities like road cycling, horseback riding, or motorcycle riding, and hard workouts in heat and humidity.

Swimming, Pool Time, and Open Water Safety

Swimming is a low-impact exercise that works well during pregnancy. It's generally pregnancy-friendly in calm, supervised settings, which is why many people find it easier than land-based workouts in hot weather.

A few water activities are not safe. Scuba diving should be avoided because of the risk of fetal decompression illness. High-impact water activities like jet skiing, water skiing, or surfing in strong waves should also be avoided.

A few simple habits can make pool time safer:

• Shower after swimming to help cut down on irritation and yeast infection risk.
• Be careful on wet pool decks, and avoid diving or jumping from heights.
• Avoid wading or swimming in freshwater lakes, rivers, or streams, which can harbor parasites that cause schistosomiasis.
• Don't walk barefoot on beach sand, since soil-transmitted parasites like hookworm can penetrate the skin through bare feet.
• Skip hot tubs and heated spas, even for a short soak.

Beach and Poolside Sun Safety

Pregnancy hormones can make skin more sensitive to UV rays. That can increase your risk of sunburn and melasma, sometimes called the "mask of pregnancy."

Shade matters more than people think. Sit under an umbrella or cabana, and use broad-spectrum SPF 30+ sunscreen, a wide-brim hat, and lightweight, loose-fitting clothing. Bring water with you, and plan cooling breaks every 1–2 hours in shade or air conditioning.

The table below gives a quick reference for planning your summer activity days.

Safer Activities	Activities to Modify	Activities to Avoid
Swimming and snorkeling	Outdoor walking (early morning or late evening only)	Scuba diving
Prenatal yoga and gentle stretching	Beach visits (stay under umbrellas and wear shoes)	Water skiing, jet skiing, or surfing in strong waves
Indoor mall walking	Stationary cycling (indoors with air conditioning)	Diving or jumping from heights
Low-impact exercise on flat, shaded routes	Reduce exercise intensity in high humidity	Contact sports or high-fall-risk activities
		Hot tubs, saunas, or heated spas
		Wading in freshwater lakes or streams

If your summer plans include getting there by car or plane, use the next checklist for travel-specific tips.

Summer Travel Do's and Don'ts: Road Trips and Flights

Timing, Planning, and What to Pack

When summer plans include a getaway, shape the trip around your trimester and your provider's advice.

For many people, the second trimester - about weeks 14 through 28 - is the easiest time to travel. By the third trimester, travel usually takes more prep, and many providers suggest staying closer to home as your due date gets closer. Most domestic airlines let pregnant passengers fly up to 36 weeks, but some international carriers stop earlier, often between 28 and 34 weeks. Cruise lines may stop travel after 24 to 28 weeks.

Before you go anywhere, check in with your obstetric provider 4 to 6 weeks ahead of time. Bring your prenatal records, your provider's contact information, prenatal vitamins, compression stockings if your provider wants you to use them, and a small kit with acetaminophen and antacids. It also helps to know where the nearest hospital with obstetric care is at your destination.

The road-trip and flight checklists below make packing and planning much simpler.

Road Trip Checklist

Seatbelt placement matters - a lot. The lap belt goes under the belly and across the hips, never across the abdomen. The shoulder belt should sit between the breasts. Leave airbags on, but slide the seat back as far as you can.

Sitting for more than four hours can increase the risk of deep vein thrombosis (DVT). That’s why it’s smart to plan stops every 1 to 2 hours so you can get out, walk, and stretch. Try to keep total driving time to 5 to 6 hours per day, run the air conditioning, and keep a refillable water bottle within reach. Water-rich snacks like watermelon or cucumber can help on long stretches too.

Flights bring a different set of issues, especially with circulation and dry cabin air.

Flying Checklist

The table below lays out the main do's and don'ts for both types of travel side by side.

Category	Road Trip	Flight
Movement	Stop every 1 to 2 hours to walk and stretch	Walk the aisle every 60 to 90 minutes
Seatbelt	Lap belt under belly, across hips; shoulder belt between breasts	Fasten low across the hips, under the belly
Circulation	Wear compression socks; flex ankles at stops	Wear compression stockings; flex ankles while seated
Hydration	Carry a refillable water bottle; eat water-rich snacks	Sip water frequently to counter dry cabin air
Seating	Move seat back as far as you can	Book an aisle seat for easier movement and bathroom access
What to avoid	Don't drive more than 5 to 6 hours per day	Skip carbonated drinks and gas-producing foods.

On flights, book an aisle seat. It makes getting up to move around or use the bathroom a lot easier. Cabin air is dry, so drink water steadily during the flight instead of waiting until you feel thirsty. Skip carbonated drinks too - gas expands at altitude, which can lead to bloating or pain. If your provider has told you to wear compression stockings, use them on any flight longer than four hours.

If you're in the third trimester, check your airline's pregnancy policy before you book. If needed, carry a provider's note or fitness-to-travel letter.

Amusement Outings, Warning Signs, and Delivery Planning

Amusement Parks, Fairs, and Crowded Summer Events

After you plan for travel, use the same heat precautions for amusement parks, county fairs, and summer festivals. These outings can still be doable during pregnancy, but it helps to keep things low-key. Pick attractions that don’t take much physical effort, and build in time to cool off.

Indoor attractions, shady areas, and planned breaks can make a big difference. If you want to be outside, aim for the cooler parts of the day instead of the hottest afternoon hours.

Skip rides with sudden starts or stops, steep drops, high speeds, or any chance of impact to your abdomen. Heat, long walks, and standing for long stretches can make dizziness and swelling more likely. Wear loose, breathable clothes and a wide-brimmed hat. If you’ll be on your feet for a while, compression socks may help. And when you get the chance, sit down.

Signs It Is Time to Stop and Call Your Provider

Stop the outing right away if any of these warning signs show up.

Category	Warning Signs
Pregnancy-specific	Vaginal bleeding, leaking fluid, decreased fetal movement, regular contractions before 37 weeks, severe abdominal pain
Heat illness	Overheating that does not improve after moving to a cool place and drinking fluids
Heart and lungs	Chest pain, palpitations, trouble breathing, severe shortness of breath
Neurological	Severe or worsening headache, sudden vision changes or seeing spots
Circulation	Pain, redness, or swelling in one leg only

Treat heat stroke as an emergency. If dizziness or nausea lasts longer than 30 minutes, get medical care.

Planning Ahead for Delivery and Newborn Stem Cell Banking

As pregnancy gets closer to term, it makes sense to think less about outings and more about delivery plans. If you’re near your due date, have signs of preterm labor, or have a high-risk condition like placenta previa or preeclampsia, stay close to home.

If you’re traveling in the third trimester, especially after week 28, look up the nearest hospital with obstetric and neonatal care before you arrive. Carry your prenatal records, blood type details, your provider’s contact information, and a letter that confirms your due date and that you’re fit to travel.

If you are considering cord blood banking benefits, contact Americord Registry early to discuss your due date, travel plans, and delivery hospital. Finish registration, let your delivery provider know, and pack the collection kit before labor starts.

FAQs

Can summer heat harm my baby?

Yes. Summer heat can be hard on pregnancy because your body doesn't cool itself as easily. That means your risk of dehydration, heat exhaustion, and heat stroke goes up.

That matters because excessive heat and dehydration are linked to preterm birth, stillbirth, and low birth weight. Overheating during the first trimester may also increase the risk of certain birth defects.

A couple of simple steps can help: drink enough water and stay out of the sun during the hottest part of the day. Those habits can help protect both you and your baby.

Is it safe to travel alone while pregnant?

Travel during a healthy pregnancy is generally safe. That said, experts suggest skipping solo travel when you can.

Talk with your healthcare provider a few weeks before your trip. Go over your health needs, your itinerary, and any risks tied to where you're going.

If you do travel, make sure you have a plan for medical emergencies. Bring your medical records and insurance information with you.

What should I pack for a summer trip during pregnancy?

Keep key medical and comfort items in your purse or carry-on so you can grab them fast when you need them.

Pack:

• a copy of your prenatal medical records, your provider’s contact information, your insurance card, and any prescription medications or supplements
• a refillable water bottle, pregnancy-safe sunscreen with SPF 30 or higher, and compression socks
• easy-to-digest snacks like trail mix, fruit, or granola bars
