Introduction

Excessive exposure to air conditioning, combined with a damp environment and weak individual metabolism, may exacerbate dampness in the body. If one remains in an air-conditioned room for prolonged periods in a humid environment, or if the air conditioner filter is not cleaned timely, cold and damp air may more easily enter the body. Additionally, air conditioning reduces perspiration, making it easier for damp pathogens to accumulate within the body. This may lead to symptoms of dampness accumulation such as heaviness in the body and joint discomfort, potentially worsening the condition.

Generally speaking, excessive exposure to air conditioning combined with a humid environment and weak individual water metabolism may increase dampness in the body. However, if the environment is dry and the body's water metabolism functions normally, this typically does not occur. If you have concerns, it is recommended to seek medical advice in advance. Detailed analysis is as follows:

If staying long-term in an air-conditioned room with a humid environment, or if the air conditioner filter is not cleaned timely, cold and damp air may easily enter the body. Additionally, air conditioning reduces perspiration, making it easier for dampness to accumulate internally, which may trigger symptoms of excessive dampness such as bodily heaviness and joint discomfort. In such cases, internal dampness may be exacerbated.

If the air-conditioned environment is dry, and regular ventilation and filter cleaning are maintained, along with good spleen and stomach function allowing normal water metabolism, even with frequent exposure to air conditioning, obvious symptoms of excessive dampness might not occur, and it may not be directly associated with increased dampness.

When using air conditioning, attention should be paid to regulating environmental humidity and regularly opening windows for ventilation, avoiding staying in enclosed spaces for extended periods. If persistent symptoms such as physical fatigue and thick, greasy tongue coating occur, reduce the use of air conditioning and seek timely medical attention to determine if symptoms are related to dampness before proceeding with appropriate management.

How to properly regulate cold-damp-heat constitution

Adjusting a constitution characterized by cold, dampness, and heat typically involves modifying dietary patterns and using traditional Chinese medicine therapies. Long-term persistence is essential when regulating such a constitution; quick results should not be expected. If significant fatigue, abdominal distension, or worsening of thick, greasy tongue coating occur during the process, it is advisable to consult a professional TCM practitioner to develop a personalized plan. Daily attention should be paid to bodily responses, and调理 methods should be adjusted according to seasonal changes.

Is eczema caused by excessive dampness in the body?

When eczema presents with skin erythema, papules, and exudation, and the patient simultaneously exhibits symptoms such as thick, greasy tongue coating, sticky bowel movements, and heavy limbs, it may be related to excessive internal dampness. Accumulation of dampness in the skin can easily trigger inflammatory responses, leading to eczema flare-ups or worsening. In such cases, resolving dampness through regulation may help alleviate symptoms.
