Swollen feet usually go down within a few hours when you combine elevation, movement, and a few simple changes to your routine. The swelling happens when fluid builds up in your tissues faster than your body can drain it, and most of the time, you can reverse it at home by helping that fluid move back into circulation.
Elevate Your Feet Above Your Heart
The fastest way to reduce swelling is gravity. Lie down and prop your feet on pillows so they sit above the level of your heart. This position lets pooled fluid drain back toward your core instead of sitting in your ankles and feet. Aim for about 15 minutes at a time, three to four times a day. If you can only do it once, the best time is at the end of the day when swelling tends to peak.
A recliner alone usually isn’t enough. Your feet need to be genuinely higher than your chest, so lying flat on a couch or bed with a stack of pillows under your calves works better than simply kicking back in a chair.
Use Your Calf Muscles as a Pump
Your calf muscles act like a built-in pump for your circulatory system. Every time they contract, they squeeze fluid and blood upward out of your lower legs. Sitting or standing still for long stretches lets fluid pool, so even small movements make a measurable difference. In one study, simple calf contractions while seated reduced leg fluid volume by over 50 milliliters, and tiptoe raises produced even larger fluid shifts of around 80 milliliters per rep.
You don’t need a gym. Try these throughout the day:
- Calf raises: Stand and slowly rise onto your toes, then lower back down. Repeat 15 to 20 times.
- Ankle pumps: While sitting or lying down, point your toes away from you, then pull them back toward your shin. This activates the same pump mechanism.
- Walking: Even a 10-minute walk engages your calves, feet, and ankles enough to push fluid back into circulation.
If you work at a desk, set a reminder to do ankle pumps or calf raises every 30 to 60 minutes. The key is breaking up long stretches of stillness.
Cut Back on Sodium
Salt makes your body hold onto water. If your feet are swelling regularly, your sodium intake is one of the first things to look at. A reasonable target is under 2,000 milligrams per day, which is tighter than what most people eat. The average American consumes well over 3,000 milligrams daily, and most of it comes from processed and packaged foods rather than the salt shaker on the table.
The biggest offenders are canned soups, deli meats, cheese, chips, fast food, and frozen meals. Cooking more at home and reading nutrition labels gives you control over how much sodium you’re actually taking in. You’ll often notice a difference in swelling within a day or two of cutting back.
Drink More Water, Not Less
It sounds backward, but staying well hydrated actually helps reduce fluid retention. When your body senses it isn’t getting enough water, it holds onto what it has, which can worsen swelling. Drinking enough water signals your kidneys to release excess fluid rather than store it. There’s no magic number, but if your urine is pale yellow, you’re generally in good shape.
Try Compression Socks
Compression socks apply gentle, graduated pressure that prevents fluid from settling into your feet and ankles. They’re most effective when you put them on in the morning before swelling starts, rather than after your feet are already puffy.
Compression levels are measured in millimeters of mercury (mmHg), and the right level depends on how much swelling you’re dealing with. For mild, everyday swelling from sitting or standing too long, 15 to 20 mmHg provides light support and is available without a prescription. A level of 20 to 30 mmHg is the most commonly prescribed range for moderate swelling or chronic issues like venous insufficiency. Higher levels (30 to 40 mmHg and above) are reserved for more significant conditions and should be fitted with guidance from a healthcare provider.
Soak in Epsom Salt
A warm Epsom salt bath is a popular home remedy, and there is some supporting evidence that soaking in magnesium sulfate for 10 to 15 minutes can help reduce swelling and discomfort in the lower extremities. The warm water itself also helps by promoting circulation. This isn’t a substitute for the strategies above, but it can provide noticeable short-term relief, especially at the end of a long day.
Check Your Medications
Several common medications cause foot and ankle swelling as a side effect. Blood pressure drugs called calcium channel blockers are among the worst offenders. Nearly half the people taking them experience some degree of swelling. Other medications linked to puffy feet include certain blood pressure drugs like beta blockers, hormone treatments (including estrogen, testosterone, and corticosteroids), nerve pain medications like gabapentin and pregabalin, anti-inflammatory painkillers like ibuprofen and naproxen, and some diabetes and antidepressant medications.
If you started a new medication and your feet began swelling shortly after, that connection is worth raising with whoever prescribed it. Don’t stop taking a medication on your own, but there may be alternatives that don’t cause this side effect.
What’s Causing the Swelling
Occasional swelling after a long flight, a hot day, or hours on your feet is common and harmless. It happens because gravity pulls fluid downward and your circulation can’t keep up. Pregnancy, eating a salty meal, and alcohol can all trigger temporary puffiness for similar reasons.
Swelling that keeps coming back or won’t go away can point to something deeper. Chronic venous insufficiency, where the valves in your leg veins weaken and let blood pool, is one of the most common causes. Heart, kidney, or liver problems can also lead to persistent edema because these organs regulate how your body handles fluid. Thyroid disease and sleep apnea are less obvious culprits that can contribute as well.
Signs That Need Urgent Attention
Most foot swelling is a nuisance, not an emergency. But certain patterns are red flags. Swelling in only one leg, especially if it’s accompanied by pain, warmth, or redness in the calf, can signal a blood clot known as deep vein thrombosis. This is particularly concerning if it came on suddenly or followed a long period of immobility like a road trip or surgery.
A blood clot becomes dangerous if a piece breaks off and travels to the lungs. Seek emergency care if you experience sudden shortness of breath, chest pain that worsens when you breathe or cough, a rapid pulse, dizziness or fainting, or coughing up blood. These are signs of a pulmonary embolism, and they require immediate treatment.
