Staying Comfortable Through Summer Pregnancy: Tips for Back Pain and Swelling

Let’s be honest—pregnancy in the summer can be a sweaty, swollen, achy experience.

Between the rising temperatures, expanding belly, and shifting hormones, it’s no surprise many expectant mums feel like they’re wilting by mid-afternoon. If you’re navigating the third trimester in a heatwave (or even a typical British summer), you’re not alone. At The Octagon Clinic, we regularly support pregnant women who are battling common summer complaints like back pain, ankle swelling, and that general sense of overheating.

The good news? There are ways to feel more comfortable—without spending all day in front of a fan. Here are our favourite practical tips, plus when to consider extra support like chiropractic care or pregnancy-safe Pilates.

1. Hydration is more important than ever

Pregnancy already increases your fluid needs—but in summer, you’ll sweat more too. This combination makes hydration essential for:

Preventing heat exhaustion
Reducing swelling (yes, really)
Supporting healthy circulation

Aim for at least 8–10 glasses of water per day, and keep a bottle nearby. If you’re struggling, try infusing your water with cucumber, lemon, or mint for a refreshing twist. Coconut water can also be a gentle source of electrolytes if you’re feeling depleted.

Tip: Sip steadily throughout the day. A sudden downing of a pint won’t hydrate you the same way as consistent small drinks.

2. Support your changing body with gentle movement

When your back aches and your ankles are ballooning, exercise might be the last thing on your mind. But gentle, regular movement is one of the best things you can do to improve circulation and ease pressure on joints.

Some helpful options:

Pregnancy-safe Pilates: Builds core strength and pelvic stability, easing strain on the lower back.
Swimming or aqua classes: The water supports your bump and joints while offering full-body relief.
Short walks: Even 10–15 minutes around the block a few times a day can help prevent fluid pooling in your lower legs.

Always check with your midwife or GP before starting new exercise routines.

3. Swollen ankles? Elevate and cool

Swelling (oedema) is incredibly common, especially in the heat. To help:

Elevate your feet when resting—ideally above hip level
Avoid standing or sitting for long periods without a break
Use a cool compress on swollen feet and ankles
Consider compression socks if recommended by a healthcare provider

Cutting back on salt can make a difference too. It helps reduce water retention, which is a sneaky culprit behind that “tight shoe” feeling by midday.

4. Mind your posture (and your pelvis)

A growing bump shifts your centre of gravity, which often leads to:

Lower back pain
Sacroiliac joint discomfort
Pelvic pressureWe see this regularly in our clinic, and simple ergonomic tweaks can really help:
Sit with a rolled towel or cushion behind your lower back
Avoid crossing your legs (it can worsen swelling and pressure)
Use a pregnancy support pillow for sleep—it supports hips, spine, and bump in one go

Don’t underestimate the benefit of a well-fitted maternity belt if your bump is pulling your posture forward.

5. When to seek hands-on support

If you’re doing all the above and still feeling sore, stiff, or uncomfortable—you don’t have to power through.

At The Octagon Clinic, our pregnancy-trained chiropractors offer gentle, safe adjustments tailored for your changing body. We help realign the spine and pelvis, often relieving back or hip pain that’s worsened by postural strain.

Our pregnancy Pilates instructors also work closely with women at every stage, building strength and mobility in a way that feels safe and supportive—not exhausting.

It’s not about “fixing” your body—it’s about supporting it through this incredible transition.

Final Thought: You don’t have to suffer through it

Pregnancy in the heat isn’t easy—but with the right strategies and support, it can be more manageable. Whether it’s adjusting your daily habits, getting hands-on care, or simply knowing which symptoms are common and which need attention—you’re not alone.

If you’re feeling uncomfortable, our team at The Octagon Clinic is here to help.
