Elevating your feet, staying active, and reducing salt intake are the most effective ways to bring down swollen feet and ankles at home. Most swelling in the lower legs comes from fluid pooling due to gravity, prolonged sitting or standing, or excess sodium in the diet. The good news: simple physical strategies can move that fluid out within hours, and a few habit changes can keep it from coming back.
Elevate Your Feet Above Your Heart
The single fastest way to reduce swelling is to lie down and prop your feet up so they’re higher than your chest. Gravity has been pulling fluid downward all day, and elevation reverses that flow, letting it drain back toward your core where your kidneys can process it. A stack of pillows, a couch armrest, or a recliner all work. The key is getting your feet genuinely above heart level, not just slightly raised on an ottoman.
Try to elevate for at least 20 to 30 minutes at a time, and do it multiple times throughout the day if swelling is persistent. Many people notice their feet are most swollen in the evening, so elevating after dinner is a good routine to build. If you work at a desk, even a short midday session with your legs up on a chair can make a noticeable difference.
Use Ankle Pumps to Activate Your Calf Muscles
Your calf muscles act as a pump for the veins in your lower legs. When you contract them, they squeeze fluid upward through your vessels. Sitting or standing still for hours shuts this pump off, and fluid accumulates.
Ankle pumps are the simplest way to restart it. Sit or lie with your legs extended, then point your toes toward your knees as far as you can, hold briefly, and point them away from you. Alternate back and forth for two to three minutes, and repeat two to three times per hour when you’re sitting for long stretches. You can do these at your desk, on a plane, or in bed. Walking is even better if it’s an option, since every step engages that same pumping action.
Cut Back on Sodium
Salt makes your body hold onto water. The more sodium in your bloodstream, the more fluid your kidneys retain to keep concentrations balanced. For people dealing with regular swelling, staying under 2,000 mg of sodium per day is a widely recommended target. For context, a single fast-food meal can easily contain 1,500 mg or more.
The biggest sources are processed and restaurant foods, not the salt shaker on your table. Canned soups, deli meats, frozen meals, soy sauce, and bread are common culprits. Reading nutrition labels and cooking more meals at home gives you the most control. Most people who make this switch notice less puffiness within a few days.
Drink Enough Water
It sounds counterintuitive, but drinking too little water can actually make swelling worse. When you’re dehydrated, the ratio of salt to water in your blood rises. Your brain responds by releasing a hormone that tells your kidneys to hold onto fluid rather than let it go. Staying well-hydrated keeps that signal turned off and allows your kidneys to flush excess fluid normally.
That said, chugging large amounts at once isn’t helpful either. Your body detects a sudden rush of water and triggers a reflex to dump much of it before it’s absorbed. Sipping steadily throughout the day is more effective than drinking a liter all at once.
Try Compression Socks or Stockings
Compression garments apply gentle, graduated pressure to your lower legs, helping push fluid upward and preventing it from pooling around your ankles. They come in several pressure levels, measured in millimeters of mercury (mmHg):
- 15 to 20 mmHg (mild): Good for prevention, travel, or very mild swelling. A comfortable starting point if you’ve never worn compression before.
- 20 to 30 mmHg (moderate): The most commonly recommended range for everyday edema. Balances effectiveness with comfort for daily wear.
- 30 to 40 mmHg (firm): Used for more significant or stubborn swelling, particularly in the lower legs where gravity’s pull is strongest.
Put them on first thing in the morning before swelling starts, since they’re designed to prevent fluid from accumulating rather than squeeze it out after the fact. If you’re not sure which level you need, starting at 15 to 20 mmHg lets you build tolerance.
Move Regularly Throughout the Day
Long periods of sitting or standing are the most common trigger for swollen feet in otherwise healthy people. If you work at a desk, set a reminder to stand up and walk for a few minutes every hour. If your job keeps you on your feet, take brief sitting breaks with your legs elevated when you can, and shift your weight or walk in place rather than standing motionless.
Any form of regular exercise helps long-term. Walking, swimming, and cycling all engage the muscles that push fluid out of your legs. Swimming has an added benefit: the water pressure around your body acts like natural compression and can reduce swelling during the activity itself.
How to Tell If Swelling Is More Serious
Most foot and ankle swelling is harmless, caused by gravity, heat, salt, or inactivity. But certain patterns warrant prompt medical attention.
Swelling in only one leg, especially if it comes on suddenly with pain, warmth, or redness, is a red flag for a blood clot (deep vein thrombosis). One-sided swelling always deserves a closer look. Swelling in both legs can still involve a clot, but it’s more commonly related to heart, kidney, or liver function, medication side effects, or simply lifestyle factors.
You can get a rough sense of severity by pressing a finger into the swollen area for a few seconds. If it leaves an indent that slowly fills back in, that’s called pitting edema, and the depth and rebound time indicate how significant it is. A shallow 2 mm dent that rebounds immediately is mild (grade 1). An 8 mm pit that takes two to three minutes to fill back in is severe (grade 4) and needs medical evaluation.
Swollen Feet During Pregnancy
Some ankle swelling during pregnancy is completely normal, especially in the third trimester, as your body carries extra blood volume and your growing uterus puts pressure on the veins returning blood from your legs. Elevation, ankle pumps, and comfortable shoes all help.
What’s not normal is sudden swelling of the hands, arms, or face, or unexpectedly rapid weight gain from fluid retention. These can be signs of preeclampsia, a serious pregnancy complication involving high blood pressure. Ankle puffiness alone is common and expected, but swelling that moves above the ankles to the hands and face, especially if paired with headaches or vision changes, needs immediate attention.
When Medication May Be Needed
If lifestyle changes aren’t enough, doctors sometimes prescribe water pills (diuretics). These work by telling your kidneys to release more salt and water into your urine, which reduces fluid volume throughout your body. There are several types that act on different parts of the kidneys, with varying strengths. Some are mild, others are potent enough for people with significant heart or kidney problems.
Diuretics treat the symptom, not the cause. If your swelling is related to a medication you’re taking (calcium channel blockers for blood pressure are a common culprit), your doctor may adjust that prescription instead. Persistent or worsening swelling that doesn’t respond to elevation, compression, and dietary changes is worth investigating, since it can point to underlying heart, kidney, or vein problems that benefit from targeted treatment.
