Swollen feet in summer heat: 9 measures that can help

Swollen ankles and feet are a frequent summer complaint, often caused by heat, prolonged sitting, or standing. While usually harmless, this swelling, known as edema, can sometimes signal more serious health conditions. Edema occurs when fluid accumulates in the tissues, most commonly affecting the feet, ankles, and lower legs. Factors contributing to this include extended periods of sitting or standing, high salt intake, excess weight, pregnancy, and varicose veins. Certain medications can also cause swelling as a side effect.

However, it's crucial to recognize when swelling might indicate a chronic venous insufficiency, or problems with the heart, kidneys, or liver. Issues with the lymphatic system, infections, or blood clots can also manifest as swollen legs. If the swelling is mild and you feel otherwise well, simple home remedies can offer relief. Regular movement is key; walking helps pump blood from the legs back to the heart. For those with sedentary jobs, frequent breaks to stand, walk, or exercise the feet and ankles are recommended. Simple exercises like rising onto toes, ankle rotations, and flexing the feet can make a difference.

Elevating the legs is another effective measure. Resting with your feet propped up on pillows, higher than your body, can aid fluid and blood return from the lower extremities. Dietary adjustments are also important. Reducing salt intake can prevent fluid retention, so be mindful of hidden salts in processed foods, cheeses, and cured meats. Maintaining a healthy weight is also beneficial, as excess weight puts additional strain on the legs. Gradual weight loss can alleviate pressure and improve circulation, offering numerous health benefits beyond just reducing leg swelling.
