Your lymphatic system acts like your body’s built-in drainage network, collecting excess fluid from tissues and helping return it to your bloodstream. Unlike your heart pumping blood, the lymphatic system doesn’t have its own central pump—it relies heavily on movement, muscle contractions, and breathing to keep lymph moving.
When that flow slows down, fluid can accumulate in your tissues. That can leave you waking up puffy, feeling swollen or heavy, noticing stubborn bloating, or simply not feeling like yourself in your own body.
