Why Your Ankles Swell in the Heat — and What Yoga Therapy Can Do About It

Legs Up the Wall

Summer arrives and suddenly your shoes feel tight by mid-afternoon. Your ankles look puffier than usual. You sit down at the end of the day and notice that dull, heavy feeling in your lower legs. Sound familiar?

You're not imagining it. Heat genuinely makes swelling worse — and there are clear physiological reasons why. The good news is that yoga therapy offers some beautifully simple, effective ways to help your body drain that fluid and feel lighter again.

What's Actually Happening in Your Body

When temperatures rise, your body's first priority is cooling itself down. To do that, it triggers vasodilation — your blood vessels widen to allow more blood flow close to the skin's surface, releasing heat. This is clever and necessary. But it also means more fluid leaks out of the capillaries and into the surrounding tissue.

Gravity does the rest. That excess fluid pools in the lowest point of your body — your feet and ankles. This is called dependent oedema, and it's extremely common in summer, especially if you're sitting or standing for long periods.

At the same time, your lymphatic system — which is responsible for clearing that fluid — slows down. The lymphatic system doesn't have its own pump like the heart. It relies on movement, breath, and muscle contractions to keep fluid moving. In the heat, when we naturally slow down and rest more, lymphatic drainage slows too.

"The lymphatic system has no pump of its own.

Movement, breath, and the gentle squeeze of your muscles

are what keep it flowing."

A few other factors make it worse:

• Dehydration — paradoxically, when you're dehydrated your body retains more fluid

• High sodium intake — salt binds water in the tissues

• Prolonged sitting or standing — the calf muscle pump stops working

• Hormonal shifts — particularly during perimenopause, fluid retention can increase significantly

• 
  

The Yoga Therapy Approach

Yoga therapy works with swollen ankles from several angles at once: reversing gravity through inversions, activating the body's natural fluid pumps, supporting the lymphatic system, and calming the nervous system to reduce overall inflammation.

Here's how I approach it:

1. Inversions First

The single most effective thing you can do is get your legs above your heart. This directly counters gravity and allows fluid to drain back toward the core.

• Viparita Karani (Legs Up the Wall) — the gold standard. Stay for 5–15 minutes. Use a folded blanket under your hips if your hamstrings are tight.

• Supported Supta Baddha Konasana — lie on your back with soles of feet together, legs elevated on a bolster. Deeply relaxing and draining at the same time.

• Supported Bridge Pose — a gentler option if full inversions aren't accessible.

  
  

2. Wake Up the Calf Pump

Your calf muscles act as a second heart. Every time they contract, they squeeze blood and lymph upward through the veins. In summer, when we're more sedentary, this pump slows right down.

Before getting into any floor poses, spend a few minutes activating it:

• Ankle circles — 10 in each direction

• Foot flexion and extension — 20 slow pumps

• Heel raises — standing or seated, 15–20 reps

• Toe spreads — spread and lift all toes, hold 5 seconds

• 
  

3. Yoga Poses That Support Drainage

• Adho Mukha Svanasana (Down Dog) — with active heel presses into the mat

• Utkatasana (Chair Pose) — brief holds to engage the full lower leg

• Supta Twists — the gentle compression and release supports lymph movement

• Tadasana heel-toe rocking — simple and effective, great for beginners

4. Breathwork as a Lymphatic Pump

This is something most people don't know: the diaphragm is one of the most powerful lymphatic pumps in the body. Every time you take a slow, deep belly breath, the movement of your diaphragm creates pressure changes that actively move lymph fluid through the body.

In hot weather, I also recommend cooling pranayama practices to reduce vasodilation and calm the nervous system:

• Sitali Pranayama — breathing in through a curled tongue, out through the nose. Genuinely cooling, and known in Ayurveda for reducing Pitta (heat) in the body.

• Sitkari — the alternative if your tongue doesn't curl naturally

• Chandra Bhedana — left nostril breathing, activating the cooling channel

• 
  

5. Self-Care Between Sessions

Daily Habits That Help

• Drink more water than feels necessary — dehydration makes retention worse

• Reduce sodium, especially processed foods

• Move every 30–45 minutes if sitting for long periods

• Cool foot soaks with a few drops of peppermint or cypress essential oil (both have mild vasoconstrictive properties)

• Gentle upward leg massage before bed — ankle to knee, always moving toward the heart

• Elevate your feet while sleeping or resting

• Wear compression socks in the morning before fluid has a chance to pool

A Note on Ayurveda

From an Ayurvedic perspective, summer is Pitta season — hot, sharp, and intense. For those of us with a Pitta or Vata-Pitta constitution, the heat of summer can tip us into imbalance more easily. Cooling foods (cucumber, coconut, mint, coriander), cooling breathwork, and avoiding the midday sun are all part of a holistic approach to summer wellness that goes hand in hand with the yoga therapy tools above.

When to See Your GP

Please seek medical advice if you notice:

Pitting oedema (an indent that stays when you press the skin) · Swelling in one leg only · Swelling alongside shortness of breath or chest pain · Redness, warmth, or pain in the swollen area · Swelling that doesn't reduce overnight with elevation

Ankle swelling in summer is usually benign, but the above signs can indicate conditions that need medical assessment before yoga therapy continues.

Final Thought

Your body is always communicating. Puffy ankles in summer are not a malfunction — they're your body doing its best to manage heat. Yoga therapy supports that process, works with the body's own intelligence, and gives you practical tools you can use every single day.

If you'd like to explore yoga therapy for specific concerns — whether that's swelling, chronic tension, perimenopause symptoms, or nervous system regulation — I offer one-to-one sessions either in person or online.
