Staying Hydrated During Pregnancy: Why It Matters Even More in 35°C+ Heat

With the extreme temperatures we've experienced over the last few days, it's a good time to remind ourselves just how important hydration is—especially during pregnancy.

Staying well hydrated is essential for both physical health and mental wellbeing. While everyone is affected by hot weather, pregnant women are particularly vulnerable to dehydration because pregnancy places additional demands on the body.

When temperatures rise above 35°C, your body relies heavily on sweating to cool itself down. As sweat evaporates, it removes heat—but it also causes you to lose water and important electrolytes. If those losses aren't replaced, your body's ability to regulate temperature and function properly starts to decline.

Why Hydration Matters During Pregnancy

During pregnancy, your body needs extra fluids to support your growing baby, maintain healthy amniotic fluid levels, increase blood volume, and help transport nutrients throughout the body. Dehydration can leave you feeling unwell much more quickly than usual and may contribute to headaches, fatigue, dizziness, constipation, and overheating.

Many common pregnancy symptoms can actually worsen when you're not drinking enough.

What Happens When We Don't Drink Enough in Hot Weather?

Even mild dehydration can have noticeable effects, including:

• Headaches

• Fatigue and low energy

• Dizziness or light-headedness

• Reduced concentration and mental clarity

• Dry mouth

• Darker urine

• Increased irritability

If you've been feeling more tired than usual, struggling to concentrate, or experiencing more headaches during these hot days, dehydration could be playing a role.

In more severe cases, dehydration can make it harder for your body to regulate its temperature, increasing the risk of heat exhaustion.

Easy Ways to Increase Your Water Intake

Let's be honest—drinking enough water isn't always easy, especially if you're dealing with nausea, food aversions, or simply don't enjoy plain water. Here are some simple ways to boost your fluid intake without feeling like you're forcing it.

1. Create "Spa Water"

Add slices of cucumber, lemon, strawberries, mint, or orange to your water bottle. A little natural flavour can make drinking water much more appealing and encourage you to sip throughout the day.

2. Eat Your Water

Many fruits and vegetables have a very high water content and can contribute to your overall hydration.

Some excellent options include:

• Watermelon

• Cucumber (around 95–96% water)

• Strawberries

• Tomatoes

• Celery

Keeping these foods prepared and ready to snack on can make a surprising difference.

3. Make Homemade Ice Lollies

Blend fruit such as strawberries, watermelon, mango, or peaches with water or yoghurt and freeze into ice lolly moulds. They're refreshing, hydrating, and a perfect way to cool down on hot afternoons.

4. Keep Water Visible

A simple trick that works for many people is keeping a water bottle within arm's reach wherever you are. If you can see it, you're more likely to drink from it.

5. Set Small Goals Throughout the Day

Rather than trying to drink large amounts at once, aim to finish one bottle by mid-morning, another by lunch, and continue steadily throughout the afternoon and evening.

Signs You May Need More Fluids

A useful rule of thumb is this: if you're already feeling very thirsty, developing a headache, feeling dizzy, or noticing dark urine in 35°C+ heat, you're likely already becoming dehydrated and should start rehydrating promptly.

A Final Thought

Hot weather can be exhausting at the best of times, and pregnancy adds another layer of challenge. Be gentle with yourself, take breaks in cool environments where possible, and make hydration a priority.

Sometimes the simplest interventions—an extra glass of water, a bowl of watermelon, or a refill of your water bottle—can have a noticeable impact on how you feel.
