When dealing with swollen feet, also known as edema, the single best drink is pure water. It might seem counterintuitive to drink more fluid when your body is retaining it, but dehydration actually triggers the body to hold onto water, which exacerbates swelling. Proper hydration helps flush out excess sodium, which is a primary culprit of fluid retention. Other beneficial drinks include dandelion tea, which acts as a natural diuretic, and lemon water, which can help with detoxification and fluid balance. Cranberry juice (unsweetened) is also often recommended for its mild diuretic properties. However, it is equally important to know what to avoid: drinks high in sodium, sugar, and caffeine, as well as alcoholic beverages, can significantly worsen swelling by dehydrating the body and causing it to store fluid. For those with persistent or severe swelling, it is always best to consult a medical professional, as edema can sometimes be a symptom of underlying heart, kidney, or liver issues. Alongside drinking water, elevating your feet above your heart and reducing salt intake are the most effective ways to find relief at home.
