Swollen ankles and feet usually respond well to a combination of elevation, movement, and dietary changes. Most cases stem from fluid pooling in the lower legs after prolonged sitting or standing, though chronic swelling can signal an underlying condition worth investigating. The good news: several effective strategies work within hours, and longer-term habits can prevent the swelling from returning.
Why Feet and Ankles Swell
Gravity pulls fluid downward throughout the day, and your lower legs are the lowest point. When you sit at a desk, stand behind a counter, or travel on a long flight, blood and lymph fluid accumulate in the tissue around your ankles and feet. This is called peripheral edema, and it’s extremely common.
Beyond gravity, several factors make swelling worse: eating too much salt, being overweight, pregnancy, certain medications (especially blood pressure drugs and anti-inflammatories), and conditions affecting the heart, kidneys, or liver. Identifying the underlying cause matters because it determines whether home strategies alone will solve the problem or whether you need medical treatment.
Elevate Your Legs Above Heart Level
The single fastest way to reduce swelling is to get off your feet and prop them up. Ideally, your feet should rest at or above the level of your heart, which means lying on a couch or bed with pillows under your calves rather than simply resting them on a low footstool while sitting upright. This position reverses gravity’s effect, letting trapped fluid drain back toward your core through your veins and lymphatic vessels.
For mild swelling, elevation for 20 to 30 minutes several times a day is usually enough. Harvard Health Publishing notes that swelling from prolonged standing or sitting should disappear over several hours once you elevate. If your job keeps you seated or standing most of the day, even short elevation breaks during lunch or after work make a noticeable difference.
Use Calf Muscle Exercises to Pump Fluid Out
Your calf muscles act as a natural pump for your circulatory system. Every time they contract, they squeeze the veins in your lower leg and push blood upward toward your heart. When you sit still for hours, that pump shuts off and fluid stagnates. Targeted exercises restart it.
The most effective exercise is the ankle pump: pull your toes up toward your shin, then point them down toward the floor. Repeat 5 to 10 times. You can do this sitting at your desk, lying in bed, or even during a flight. Circling your ankle in both directions also helps reduce stiffness in a swollen joint.
Heel raises are another excellent option. While sitting with your feet flat on the floor, lift your heels while keeping your toes planted. Repeat 5 to 10 times. If you’re able to stand, hold onto a chair or counter and rise up onto the balls of your feet, then slowly lower back down for another 5 to 10 repetitions. These exercises, recommended by The Royal Marsden NHS Foundation Trust for lymphatic drainage, take under a minute and can be repeated every hour or two throughout the day.
Walking is equally valuable. Even a five-minute walk engages the calf pump continuously and helps move fluid that has settled in your ankles.
Cut Back on Sodium
Salt makes your body retain water, and that extra fluid often shows up as swelling in the feet and ankles first. The World Health Organization recommends adults consume less than 2,000 mg of sodium per day, which works out to just under a teaspoon of table salt. Most people consume significantly more than that, largely from processed foods, restaurant meals, canned soups, deli meats, and condiments.
You don’t need to eliminate salt entirely. Start by reading nutrition labels and choosing lower-sodium versions of the foods you eat most. Cooking at home gives you far more control. Seasoning with herbs, citrus, and spices instead of salt can cut your daily intake dramatically. Many people notice less puffiness in their feet within a few days of reducing sodium, especially if they were eating well above the recommended limit.
Compression Socks and Stockings
Compression garments apply gentle, graduated pressure to your lower legs, with the tightest squeeze at the ankle and decreasing pressure moving upward. This prevents fluid from pooling and supports the calf pump’s work. They’re particularly useful if you stand or sit for long stretches, travel frequently, or have varicose veins.
Over-the-counter compression socks in the 15 to 20 mmHg range work well for mild, occasional swelling. Higher-pressure stockings (20 to 30 mmHg or above) are available by prescription for more persistent edema. Put them on first thing in the morning, before swelling starts, for the best results. Wearing them after your legs are already puffy makes them harder to get on and less effective.
Stay Hydrated and Move Throughout the Day
It sounds counterintuitive, but drinking enough water actually helps reduce swelling. When you’re dehydrated, your body holds onto more sodium and fluid as a protective response. Staying well-hydrated signals your kidneys to release excess fluid rather than store it.
If your daily routine involves long periods of sitting or standing, set a reminder to change position every 30 to 60 minutes. Stand up and walk to the kitchen. Shift your weight from foot to foot. Do a set of ankle pumps. These micro-breaks prevent fluid from accumulating in the first place, which is easier than trying to reverse swelling after it develops.
Swelling During Pregnancy
Some degree of foot and ankle swelling is normal during pregnancy, especially in the third trimester. The growing uterus puts pressure on veins that return blood from the legs, and hormonal changes cause the body to retain more fluid. Elevation, gentle walking, and compression stockings all help.
What’s not normal is sudden, significant swelling of the hands, arms, or face, or rapid weight gain over a few days. These can be signs of preeclampsia, a serious pregnancy complication involving high blood pressure. Ankle swelling alone is generally considered normal during pregnancy. But swelling that appears in the arms, hands, or face, especially alongside headaches, vision changes, or upper abdominal pain, needs prompt medical attention.
When Swelling Signals Something Serious
Most foot and ankle swelling is harmless, but certain patterns deserve attention. Swelling in only one leg, particularly when accompanied by pain, cramping, warmth, or skin that looks red or purple, can indicate a deep vein thrombosis (DVT), a blood clot in the veins of the leg. DVT can sometimes occur without noticeable symptoms, which is why new one-sided swelling always warrants evaluation.
A DVT becomes dangerous if the clot breaks loose and travels to the lungs, causing a pulmonary embolism. Warning signs include sudden shortness of breath, chest pain that worsens with deep breathing or coughing, a rapid pulse, dizziness, or coughing up blood. This is a medical emergency.
Swelling that persists despite home measures, gets progressively worse over weeks, or comes with shortness of breath when lying flat may point to heart, kidney, or liver problems. In these cases, the swelling is a symptom of a larger issue, and treating the underlying condition is what ultimately resolves it. Doctors sometimes prescribe medications that help your kidneys release excess salt and water through urine, which can provide relief while the root cause is being managed.
Putting It All Together
For everyday swelling, the most effective approach combines several strategies at once: elevate your legs above heart level for 20 to 30 minutes a few times daily, do ankle pumps and heel raises throughout the day, keep sodium under 2,000 mg, wear compression socks during long periods of sitting or standing, drink plenty of water, and take regular movement breaks. Most people see meaningful improvement within a day or two. Chronic or worsening swelling that doesn’t respond to these measures points to something beyond simple fluid pooling and benefits from a medical workup to identify the cause.
