Patients with Yin deficiency are prone to catching colds. However, generally speaking, it does not cause colds. It might be that some individual patients are prone to colds, so it varies from person to person, and there is no specific situation. Yin deficiency mainly causes physical weakness, poor health, and reduced immunity, which can then easily lead to colds and other symptoms. Therefore, if Yin deficiency occurs, it is crucial to treat it promptly with medication and also to eat more foods that nourish Yin and supplement Yang in the diet.
