From a Traditional Chinese Medicine (TCM) perspective, "Damp-Heat" is the primary cause of the bodily heaviness and mental fatigue common in summer. It originates from a dysfunction in the body's fluid metabolism combined with a state of mild inflammation.Symptoms of Damp-Heat include various bodily warning signs, such as: a feeling of heaviness in the limbs, fatigue, poor digestion, oily skin, and a dry or bitter taste in the mouth.Gua Sha promotes blood circulation, activates the immune system, and guides metabolic waste out from deep tissues.The Bladder Meridian on the back is the body's largest detoxification channel; scraping this area can directly regulate the functions of the internal organs (Zang-Fu).The "sha" (the red marks that appear after treatment) is a positive sign of metabolic waste being expelled and is not a traumatic bruise.After a session, one should rehydrate with warm water, keep warm and avoid drafts, rest fully, and maintain a light diet.Precautions: Pregnant women, individuals with an extremely weak constitution, and patients with bleeding disorders should avoid Gua Sha therapy.
