Between 3 and 5 AM, during the Yin Shi period, the lung meridian is dominant. At this time, the yin and yang of the universe are alternating, and the human body's Qi and blood are transitioning from stillness to movement. If you wake up at this moment and find your body slightly damp, or even your clothes and bedding wet, while there is no heat outside—the latter is not "heat sweat," but rather a signal emitted by the body. In clinical practice, one may sweat even when it is not hot, or become perspiring with slight tension or anxiety...
Title: Understanding the Pathophysiology of "Sweating Without Heat"
In traditional Chinese medicine, sweating without heat is often associated with a body constitution that is prone to dampness and coldness. This condition is believed to be caused by an imbalance in the body's Yin and Yang, leading to a weakened spleen and kidney function. The spleen is responsible for transforming and transporting the nutrients from the food we eat, while the kidneys are responsible for storing essence and regulating water metabolism. When these organs are weakened, they fail to properly transform and transport the body's fluids, resulting in dampness accumulating in the body. This dampness can manifest as sweating without heat, especially during the early morning hours when the lung meridian is active.
Title: Prevention and Treatment of "Sweating Without Heat"
To prevent and treat sweating without heat, it is important to address the root cause of the imbalance in the body's Yin and Yang. This can be achieved through a combination of dietary adjustments, lifestyle changes, and herbal medicine. Dietarily, it is recommended to avoid cold and raw foods, as well as excessive intake of sweet and greasy foods. Instead, one should focus on consuming warm and nourishing foods, such as porridge and soups. Lifestyle changes include avoiding overexertion, ensuring adequate rest, and practicing relaxation techniques such as tai chi or qigong. In terms of herbal medicine, a practitioner of Chinese medicine may prescribe herbs that help to strengthen the spleen and kidney, such as Astragalus, Codonopsis, and Cistanche.
