Clapping hands is harmful to the kidneys or nourishing the kidneys

The impact of clapping on the kidneys depends on the specific method and frequency. Moderate clapping may promote local blood circulation, while excessive force may cause tissue damage. In traditional Chinese medicine theory, there is a reflex relationship between palm acupoints and internal organs. Gentle tapping of the palm may regulate the circulation of qi and blood by stimulating areas such as the Laogong acupoint. The vibration generated by moderate tapping can promote microcirculation in the hands, indirectly affecting the function of the organs connected to the meridians. The traditional health preservation method of Ba Duan Jin, which involves the movement of "climbing the feet with both hands to strengthen the kidneys and waist", also includes the concept of promoting the flow of qi and blood in the kidney area through physical activity. However, it should be noted that the tapping force should be slightly warm on the skin to avoid using violent strikes. Modern medicine believes that the kidneys are located in the deep retroperitoneum, and simple palm tapping is difficult to have a direct impact. Excessive force tapping may cause rupture of subcutaneous capillaries or soft tissue contusions, which can actually increase the metabolic burden on the body. Especially for patients with pre-existing kidney disease, improper external stimulation may trigger fluctuations in the condition. There have been cases in clinical practice where prolonged forceful tapping of the waist in an attempt to "tonify the kidneys" ultimately led to subcapsular hematoma.

For kidney care, it is recommended to maintain a regular sleep schedule and drink water reasonably. A daily water intake of around 2000 milliliters can help eliminate metabolic waste. Traditional dietary supplements such as yam and black sesame can be appropriately added to the diet to avoid a high salt and high protein diet that exacerbates kidney load. Moderate aerobic exercise such as brisk walking and swimming can improve overall blood circulation more effectively than simply tapping. If there are abnormal symptoms such as increased nocturia and lower limb swelling, timely medical examination should be sought instead of relying on physical stimulation such as patting.
