Elevating your legs above heart level for 15 minutes, three to four times a day, is the single fastest way to reduce swelling in your legs and feet. But lasting relief usually requires a combination of strategies: compression, movement, dietary changes, and identifying whatever is driving the fluid buildup in the first place. Here’s how to approach each one.
Elevate Your Legs the Right Way
Elevation works by using gravity to move pooled fluid back toward your heart. The key detail most people get wrong is height: your legs need to be above the level of your heart, not just propped on an ottoman. Lying on your back with your legs on a stack of pillows or resting them up against a wall gets the angle right. Aim for about 15 minutes per session, three to four times throughout the day. If you work at a desk or stand for long periods, even a short midday session can make a noticeable difference by evening.
Use Compression Stockings
Compression stockings apply graduated pressure to your lower legs, preventing fluid from settling into your tissues. They come in different pressure levels measured in mmHg. For everyday swelling caused by prolonged sitting or standing, light compression in the 10 to 15 mmHg range is effective at reducing fluid buildup and is comfortable enough to wear all day. A step up, 15 to 20 mmHg, works well for moderate swelling. Stockings rated 20 to 30 mmHg are considered medical grade and are typically used for more persistent edema or varicose veins.
Put them on first thing in the morning before swelling has a chance to develop. If you wait until your legs are already puffy, they’ll be harder to pull on and less effective. Knee-length stockings handle most lower leg and ankle swelling; thigh-high versions are available if swelling extends above the knee.
Move Your Feet and Ankles Throughout the Day
Your calf muscles act as a pump that pushes blood and fluid back up toward your heart. When you sit or stand still for hours, that pump barely activates and fluid pools in your lower legs. Walking is the simplest fix, but when you can’t get up, ankle pump exercises work surprisingly well. Point your toes down for one second, then pull them up toward your shin for one second, and repeat. Research on blood flow during these exercises shows that continuous repetitions with no rest between movements produce the strongest effect on pushing fluid through the veins. Do 20 to 30 repetitions several times a day, especially during long flights, car rides, or desk work.
Any form of regular movement helps over time. Swimming is particularly effective because the water pressure itself acts like natural compression on your legs, and the horizontal position encourages fluid to drain. Walking, cycling, and yoga all engage the calf pump and improve circulation.
Try Gentle Lymphatic Massage
Lymphatic drainage massage uses very light pressure to coax trapped fluid toward your lymph nodes, where it can be reabsorbed. This isn’t a deep tissue massage. The strokes are gentle, just enough to stretch the skin, and always move in a specific direction: toward the heart.
Start at your toes and stretch the skin on your foot toward your ankle. Move to your lower leg and stroke upward toward your knee. On your thigh, work from the knee upward toward your hip, stretching the outer thigh toward the hip and the inner thigh outward and up. Before you start on the leg itself, it helps to gently stretch the skin near your armpit a few times, which opens up the drainage pathway higher in the lymphatic system. You can do this yourself at home for five to ten minutes per leg. The pressure should feel like you’re lightly moving the surface of the skin, not pressing into muscle.
Cut Back on Sodium
Excess sodium causes your body to hold onto extra water, expanding the volume of fluid in your tissues. The recommended daily limit is less than 2,300 mg of sodium, which is about one teaspoon of table salt. Most people consume well over that amount, largely from processed and restaurant foods rather than the salt shaker.
The biggest sources are bread, deli meats, canned soups, frozen meals, cheese, and sauces like soy sauce or ketchup. Reading nutrition labels is the most practical first step. Cooking more meals at home gives you direct control. When you reduce sodium intake, your kidneys start releasing the excess water within a day or two, and you’ll often notice your legs and feet feel noticeably less tight. Drinking enough water throughout the day actually helps this process rather than making it worse, because adequate hydration signals your body to stop retaining fluid.
Consider Magnesium for Hormonal Swelling
If your leg and foot swelling tends to worsen before your period, magnesium supplements may help. A study found that 200 mg of magnesium daily reduced premenstrual fluid retention symptoms, including swelling of the extremities and bloating, though the benefit didn’t appear until the second month of consistent use. This means it’s not a quick fix, but it can make a real difference for cyclical swelling tied to hormonal changes. Magnesium-rich foods like dark leafy greens, nuts, seeds, and dark chocolate contribute too, but a supplement provides a more reliable dose.
Check Your Medications
Several common medications cause leg swelling as a side effect. Blood pressure medications are among the most frequent culprits, particularly a class called calcium channel blockers. These are widely prescribed, and the types that most aggressively relax blood vessels are the most likely to cause puffy ankles and feet. Other blood pressure drugs, including beta blockers and certain vasodilators, can also contribute, especially at higher doses.
Beyond blood pressure medications, over-the-counter pain relievers like ibuprofen and naproxen promote sodium and fluid retention when used regularly. If you take any of these and notice persistent swelling, it’s worth discussing alternatives with your prescriber. Don’t stop a prescribed medication on your own, but knowing this connection exists gives you the right question to ask.
When Swelling Signals Something Serious
Most leg swelling is caused by gravity, inactivity, or diet, and responds well to the strategies above. But certain patterns warrant urgent attention. Swelling that appears suddenly in one leg only, especially with warmth, tenderness, or redness, is the hallmark of a deep vein thrombosis (DVT), a blood clot in the leg veins. “Sudden” in this context means developing within 72 hours. A DVT is diagnosed with an ultrasound and needs treatment right away because of the risk of the clot traveling to the lungs.
Swelling in both legs that develops gradually and worsens over weeks or months can point to heart, kidney, or liver problems. Pitting edema, where pressing a finger into the swollen area leaves a dent that takes several seconds to fill back in, often accompanies these conditions. Swelling paired with shortness of breath, chest pain, or significant weight gain over a few days also warrants prompt evaluation. These patterns don’t always mean something dangerous is happening, but they need to be ruled out rather than managed at home with elevation and compression alone.
