Swollen Ankles In The Heat: Why They Puff Up, And The Legs-Up Poses That Ease The Day’s Weight

Swollen ankles: the short answer

Ankles puff up when fluid pools in the lowest part of the body, and long sitting, long standing, hot weather and flights all make that more likely. The calf muscles are the leg’s own pump, so the plan is simple. Put the legs higher than the heart for a few minutes, then wake the calves with slow ankle and standing work. That is what Iyengar yoga does, with a wall, a bolster and a chair. Here is the article in short form:

• Sitting makes calves swell. In one study, calf volume rose 1.2% in 30 minutes of sitting still, and fell when the chair let the legs move.
• Legs up the wall is the easiest reset: five to ten minutes after a long day.
• The calf muscles pump fluid back up the leg, so standing poses, Downward Facing Dog and ankle moves all help the legs feel lighter.
• We found no trial of yoga for swollen ankles, so we say what we know from practice and what the research has not reached.
• Our free Strong Bones, Steady Feet ebook looks after the feet, ankles and legs.
• Beginner classes in Darwin teach every pose here, with props supplied.

A quick word on Iyengar yoga. Iyengar yoga is the style developed by Mr BKS Iyengar. In the 20th century he did more than anyone to set down traditional Indian yoga, through his books and his teaching, and he pioneered the use of props. It is the style we teach at Flametree, in Darwin and live online.

Why do my ankles swell at the end of the day?

Because gravity pulls fluid down, and your legs have to push it back up. The pump that does that job is the calf. Each time the calf muscle works, it squeezes the veins and sends blood and fluid back towards the heart. When you sit or stand still for hours, the pump rests, and the fluid collects around the ankles and feet.

A Norwegian vascular lab tested this in an office chair. According to PubMed, Stranden measured calf volume for 30 minutes in a chair with its tilt locked and again with the tilt free (DOI). With the chair locked, calf volume rose by 1.2% on average. With the chair free to move, it fell by 0.7%. The paper says it is well established that prolonged sitting may lead to swelling of the lower legs, and that small movements stimulate the vein pumps. It was a small lab study of movement in a chair, not a yoga trial.

In Darwin, heat is the other half of the story. In the build-up and the wet, a hot day on your feet, or a cool-air office followed by a hot car, leaves many of us with puffy ankles by evening. Flights do the same. If this is you, you are in good company.

Legs up the wall: the easiest reset

This is the pose to reach for first. Your legs rest above your heart, so gravity works for you instead of against you. Our guide to legs up the wall has the full set-up. In short:

• Put a bolster or folded blankets a little way from a wall, with a gap about the thickness of a foam brick.
• Sit sideways with your hip near the wall, lie back and swing your legs up.
• Press up through your heels, keep the knees straight and rest your arms out to the sides.
• Stay five to ten minutes. Come out sooner if you feel pain, numbness or dizziness.

Students tell us it takes the heaviness out of tired legs. That is an experience, not a promise. The usual practice cautions apply: leave it out with glaucoma, high blood pressure that is not under control, a hiatus hernia or late pregnancy. The Iyengar tradition also leaves it out during a period.

Which moves wake the calf pump?

After the rest, move. These are the ones we teach.

Ankle moves, sitting or lying

Point and flex the feet slowly, then draw slow circles each way. Do it at your desk, on a flight or while the legs rest up the wall. Short and often beats one big effort. It is the same idea as the tilting chair in the study: keep the pump moving.

Mountain Pose with a chair

Stand with the feet hip-width apart. Press all four corners of each foot into the floor: big toe, little toe and the two sides of the heel. Lift the arches, firm the thighs and stand tall. It sounds like nothing, yet the whole leg is working. Our foot pain guide explains the four corners.

Downward Facing Dog

The head is lower than the heart here, so it is a gentle inversion, and the heels reach for the floor. In class we use a chair or blocks under the hands so the pose is comfortable, and we hold it a short time and repeat.

Standing leg stretch with the heel on a chair

With a belt around the foot and the heel on a chair seat, the calf and the back of the leg lengthen while you stand tall on the other leg. Strong legs, supple ankles and a steady stance are what our Strong Bones, Steady Feet ebook is about. It cites an Australian study of 176 older people followed for a year, in which those who fell had stiffer ankles and weaker toes than those who did not (Menz and colleagues, 2006, as reported in the ebook).

Can the breath help?

In the Iyengar tradition, yes, though this is practice, not trial evidence. Geeta Iyengar taught two breaths for women in the menopause years, both lying down: Ujjayi (slow, smooth breathing through the nose) and Viloma (breathing in or out in short stages, with little pauses). She said, as quoted in our Cool, Calm And Strong ebook from her book Yoga: A Gem for Women, that these breaths “help cool down oneself, restore energy, reduce bloating, swelling and avoid night sweats”. It is a teacher’s observation, and no one has tested it for swollen ankles. We pass it on as tradition.

What has the research tested, and what has it not?

We looked for a trial of yoga for swollen ankles and did not find one. What research does show is that sitting still lets the calves swell and that movement counters it. Yoga is movement, supported rest and slow breathing, so it fits that picture. Not yet tested is not the same as wrong, but we will not claim more than we know.

A simple evening routine for a hot Darwin day

1. Five minutes of ankle circles and standing tall, hand on a chair.
2. Downward Facing Dog with blocks or a chair, two or three short holds.
3. Legs up the wall for five to ten minutes, slow breath out.
4. Finish lying quietly on your back.

Questions people ask

Why do my ankles swell when it is hot?

Long sitting or standing and heat are common companions of puffy ankles. The calf pump rests when you are still, and fluid collects at the lowest point. Moving the ankles and lifting the legs for a few minutes gives the pump a hand.

Does legs up the wall help swollen ankles?

Many students say it leaves tired legs lighter, and it puts the legs above the heart for a few minutes. We call that an experience, not a promise. No trial has tested it for swollen ankles.

How long should I stay with my legs up?

Five to ten minutes is a good start. Come out sooner if you feel pain, numbness or dizziness.

What yoga poses are good after a long day on your feet?

Legs up the wall, Mountain Pose with a chair, Downward Facing Dog with blocks or a chair, and the standing leg stretch with the heel on a chair.

Can I help swollen ankles on a flight?

Point, flex and circle the feet often, and walk the aisle when you can. In the sitting study, moving the legs counted: calf volume rose 1.2% when the seat was locked and fell when it could move.

Is there research on yoga for swollen ankles?

We did not find a trial. The research we cite shows that sitting still lets the calves swell and that movement counters it. Yoga supplies movement, supported rest and slow breath.

Which yoga breath is traditionally used for swelling?

Geeta Iyengar taught Ujjayi and Viloma, lying down, and said they reduce bloating and swelling. It is the tradition’s view, not a tested result.

Where can I learn this in Darwin?
