Swelling
Improving blood flow will make your face and legs look slimmer
Our bodies are made up of approximately 60% water, so even a slight delay in water circulation can cause swelling.
Because the face and legs are masses of muscles, if you don't move them for a long time, they will harden and the flow of blood and water will stop. Similar to relieving stiffness, you can expect to relieve swelling by warming the internal organs and replenishing minerals to relieve muscle and blood vessel tension (contraction) and drain water.
