Swollen feet usually improve with a combination of elevation, movement, compression, and dietary changes. Most cases of foot swelling result from fluid pooling in the tissues due to gravity, prolonged sitting or standing, high sodium intake, or medication side effects. The good news is that mild to moderate swelling often responds well to simple strategies you can start today.
Elevate Your Feet Above Your Heart
The single fastest way to reduce foot swelling is to lie down and prop your feet up so they sit higher than your heart. This lets gravity work in your favor, pulling fluid out of your lower legs and back into circulation. Aim to get your feet roughly 12 inches (about 30 cm) above heart level. A stack of pillows, a folded blanket on the arm of a couch, or a wedge cushion all work. Try to hold this position for 15 to 20 minutes at a time, repeating several times throughout the day.
If you work at a desk, even resting your feet on a footstool or low chair helps slow the buildup of fluid, though it won’t drain swelling as effectively as lying down with full elevation.
Use Ankle Pumps and Calf Exercises
Your calf muscles act as a pump that pushes blood and fluid upward out of your feet. When you sit or stand for hours without moving, that pump shuts off and fluid accumulates. Ankle pump exercises reactivate it.
To do an ankle pump, point your toes down as far as they’ll go, then pull them up toward your shin as far as they’ll go. That’s one repetition. You can do these slowly, holding each position for about 10 seconds, or at a faster pace of roughly one pump per second. Five minutes per session is enough to meaningfully improve blood flow. Try to fit in a round every hour or two when you’re sitting for long stretches, such as during flights, road trips, or desk work.
Walking is equally effective. Even a short five-minute walk engages your calves and helps push fluid out of your feet. If standing in place is unavoidable, shifting your weight from foot to foot or rising onto your toes and back down mimics the same pumping action.
Try Compression Socks
Compression socks apply graduated pressure to your lower legs, tightest at the ankle and looser toward the knee. This steady squeeze prevents fluid from settling into your tissues and helps push it back toward your heart.
For mild, occasional swelling, a light compression level of 15 to 20 mmHg (listed on the packaging) is a good starting point. These are widely available at pharmacies and online without a prescription. For moderate to severe swelling or chronic venous issues, medical-grade socks in the 30 to 40 mmHg range provide stronger support, though you may want guidance from a healthcare provider on sizing and fit at that level.
Put compression socks on first thing in the morning before swelling has a chance to develop. They’re harder to get on and less effective if your feet are already puffy.
Cut Back on Sodium
Salt causes your body to hold onto water, and excess sodium is one of the most common dietary drivers of foot swelling. Keeping your daily intake around 2,000 mg or less can make a noticeable difference in fluid retention. For reference, a single teaspoon of table salt contains about 2,300 mg, and many restaurant meals or processed foods contain well over 1,000 mg per serving.
The biggest sources of hidden sodium tend to be canned soups, deli meats, frozen meals, soy sauce, cheese, bread, and fast food. Reading nutrition labels and cooking more meals at home gives you far more control. Season with herbs, citrus, garlic, and spices instead of salt. Most people who reduce sodium notice less puffiness within a few days.
Drink More Water, Not Less
It sounds counterintuitive, but drinking more water can actually reduce swelling. When your body senses that water intake is low, it produces more of a hormone called vasopressin that signals your kidneys to hold onto fluid. Research on healthy volunteers found that people who habitually drank less water carried larger body fluid volumes than those who drank more. Staying well hydrated keeps that hormone level low, allowing your kidneys to release excess fluid normally.
There’s no magic number that works for everyone, but aiming for six to eight glasses a day is a reasonable baseline. If your urine is consistently dark yellow, you’re likely not drinking enough.
Soak in Epsom Salt Water
Soaking your feet in warm water with Epsom salt is a widely recommended home remedy, and there’s some evidence behind it. A small clinical study on pregnant women with foot swelling found that soaking feet in lukewarm water mixed with about 30 grams (roughly two tablespoons) of Epsom salt for 20 minutes per day reduced swelling by nearly 74% over three days. That outperformed foot exercises alone in the same study.
The warm water likely helps by promoting circulation, while the magnesium sulfate in Epsom salt may contribute to drawing fluid out of tissues. Fill a basin with comfortably warm (not hot) water, dissolve a couple of tablespoons of Epsom salt, and soak for 15 to 20 minutes. It’s low risk and inexpensive enough to try as part of your routine.
Add Natural Diuretic Foods
Certain foods gently encourage your kidneys to flush extra fluid. The Cleveland Clinic highlights several worth adding to your meals: cucumbers, watermelon, celery, asparagus, grapes, pineapple, lemons, garlic, onions, bell peppers, and ginger. These tend to be high in water content and potassium, which helps balance sodium levels.
Herbs like parsley and dandelion also have mild diuretic properties. For beverages, hibiscus tea (which is caffeine-free), green tea, and black tea can all help with fluid balance. These foods won’t produce the dramatic effect of a prescription diuretic, but as part of a lower-sodium, whole-food diet, they support your body’s ability to manage fluid on its own.
Check Your Medications
Foot swelling is a known side effect of several common medication classes. Blood pressure drugs called calcium channel blockers are among the most frequent culprits, causing swelling by widening blood vessels in a way that increases pressure in the tiny capillaries of your legs. Diabetes medications in the thiazolidinedione class have a similar effect through a different mechanism, increasing both fluid retention and blood vessel permeability.
Other medications linked to foot and leg swelling include pain drugs like ibuprofen and naproxen (NSAIDs), steroids, certain nerve pain medications, some antipsychotics, nitrate drugs for chest pain, and insulin. If your swelling started or worsened after beginning a new medication, that connection is worth raising with your prescriber. There are often alternative medications that don’t carry the same risk.
Swelling That Needs Urgent Attention
Most foot swelling is harmless and responds to the strategies above. But certain patterns signal something more serious. Swelling in only one leg, especially when paired with pain, cramping, warmth, or skin that turns red or purple, could indicate a deep vein thrombosis (a blood clot in a deep leg vein). This requires prompt medical evaluation.
If swelling in your feet is accompanied by sudden shortness of breath, chest pain that worsens when you breathe or cough, a rapid pulse, dizziness, or coughing up blood, these are warning signs of a pulmonary embolism, which is a medical emergency. Swelling that develops rapidly in both legs alongside difficulty breathing can also point to heart or kidney problems that need evaluation rather than home remedies.
