How Dry Makes You Sick

Understanding Dryness in Traditional Chinese Medicine

When we think of dryness, the first image that often comes to mind is a desert—a vast landscape with little water, dry soil, and an atmosphere lacking moisture. Dryness is not only a condition of geography or weather. According to Traditional Chinese Medicine (TCM), dryness is also one of the natural climatic influences that can affect the balance of the human body.

In nature, dryness is most closely associated with autumn. As summer gradually gives way to autumn, the air becomes cooler, moisture decreases, and plants begin to lose their vitality. Leaves turn yellow, the earth becomes dry, and the environment enters a period of transformation.

The human body, as a part of nature, responds to these seasonal changes. In Traditional Chinese Medicine, the relationship between human health and the natural environment is an essential principle. Just as the earth requires sufficient moisture to nourish plants, the human body requires adequate fluids to nourish the skin, organs, tissues, and internal systems.

Dryness itself is not necessarily harmful. It is one of the natural influences that maintains the changing rhythms of the world. However, when dryness becomes excessive or the body's nourishing fluids become insufficient, it may disturb the internal balance and develop into what Traditional Chinese Medicine describes as pathogenic dryness.

The Relationship Between Dryness and the Lung System

In Traditional Chinese Medicine, autumn corresponds to the Metal element, and the Lung system is associated with Metal.

The Lung system plays an important role in governing Qi, supporting respiration, and distributing fluids throughout the body. It is also closely connected with the skin, body hair, nose, and throat.

The Lung is traditionally described as a delicate organ that prefers moisture and is particularly sensitive to dryness.

When the body is exposed to excessive dryness, the Lung system may be among the first to experience an imbalance.

Common manifestations of dryness affecting the Lung system include:

• Dry mouth and throat

• Dry cough or coughing with little phlegm

• Dryness of the nose

• Rough, dry, or uncomfortable skin

• Increased thirst

• A feeling of insufficient moisture in the respiratory passages

• Dryness that becomes more noticeable during autumn

From the perspective of Traditional Chinese Medicine, these manifestations may reflect an imbalance in the Lung's ability to distribute fluids and maintain proper nourishment.

The Lung system is also closely connected with the body's defensive Qi, known as Wei Qi. When the Lung system is balanced, it helps maintain harmony between the internal body and the surrounding environment.

When dryness disturbs this balance, the body's natural ability to adapt to seasonal changes may become weakened.

How Excessive Dryness Consumes Body Fluids

One of the important characteristics of pathogenic dryness is its tendency to consume Jin Ye, the body's nourishing fluids.

In Traditional Chinese Medicine, Jin Ye refers to the fluids that moisten and nourish the organs, skin, muscles, joints, and other tissues.

These fluids are essential for maintaining softness, flexibility, and internal harmony.

When dryness becomes excessive, it may gradually consume these nourishing fluids. As the body loses moisture, different manifestations can develop depending on which organ systems are affected.

For example, dryness affecting the Lung may produce a dry cough and throat discomfort. Dryness affecting the skin may result in roughness, flaking, or itching. When dryness influences the Intestine system, bowel movements may become dry and difficult.

This illustrates an important principle of Traditional Chinese Medicine: although dryness may initially appear on the surface, its influence can extend into the body's internal systems.

For this reason, maintaining sufficient nourishment and supporting the proper distribution of fluids are important aspects of preserving balance.

Dryness and the Skin

Traditional Chinese Medicine teaches that the Lung governs the skin and body hair.

The skin is not considered an isolated structure. Its condition is connected with the circulation of Qi, Blood, and body fluids, as well as the balance of the internal organs.

When the Lung system distributes fluids properly, the skin receives nourishment and maintains its natural softness.

When dryness becomes excessive, the skin may lose moisture and become rough, tight, flaky, or itchy.

In the framework of Traditional Chinese Medicine, certain persistent skin conditions, including psoriasis, may involve patterns of Blood Dryness, Blood Heat, Wind-Dryness, or other internal imbalances.

Some traditional approaches also describe the accumulation of pathogenic influences as dryness-related toxins.

However, the underlying pattern may differ from person to person. The same outward manifestation does not necessarily indicate the same internal imbalance.

Traditional Chinese Medicine therefore emphasizes understanding the relationship between the skin and the body's overall condition rather than focusing only on the external appearance.

External Dryness and Internal Dryness

Traditional Chinese Medicine distinguishes between dryness that originates from the environment and dryness that develops through internal imbalance.

External Dryness

External dryness is commonly associated with seasonal and environmental changes, particularly during autumn.

When the atmosphere becomes dry, the body may be exposed to an increased drying influence.

External dryness is traditionally divided into two patterns:

Warm-Dryness

Warm-Dryness is more commonly associated with the early autumn period, when the weather remains relatively warm but moisture begins to decrease.

It may be characterized by dryness of the throat, nose, and mouth, together with a dry cough and sensations of warmth.

Cool-Dryness

Cool-Dryness is more closely associated with the later autumn period, when temperatures decrease and the air becomes both cool and dry.

It may involve dryness accompanied by an aversion to cold, nasal discomfort, or other manifestations associated with cool climatic conditions.

Internal Dryness

Internal dryness develops when the body's nourishing fluids become insufficient or are not properly distributed.

In Traditional Chinese Medicine, this may be associated with prolonged imbalance, insufficient Yin, excessive internal Heat, or disturbances involving the Lung, Stomach, Kidney, and other organ systems.

Internal dryness may be more persistent than seasonal dryness and can affect multiple parts of the body.

Understanding whether dryness is external or internal is important because Traditional Chinese Medicine approaches different patterns according to their underlying characteristics.

The Connection Between the Lung, Spleen, and Kidney

Although dryness is especially associated with the Lung, the maintenance of body fluids involves several organ systems.

The Lung distributes fluids and supports the regulation of water passages.

The Spleen transforms and transports nourishment and fluids, helping provide the resources required by the body.

The Kidney plays an important role in the regulation of water metabolism and the preservation of Yin.

These systems work together to maintain the proper movement and distribution of fluids.

When one system becomes imbalanced, the others may also be affected.

For example, insufficient transformation of fluids may reduce nourishment available to the Lung. Likewise, prolonged dryness may gradually influence the body's deeper Yin resources.

This interconnected relationship explains why Traditional Chinese Medicine considers the whole body when evaluating persistent dryness.

Supporting the Body During the Dry Season

Traditional Chinese Medicine places great importance on living in harmony with seasonal changes.

During autumn, the focus traditionally shifts toward nourishing Yin, moistening dryness, supporting the Lung, and conserving the body's essential resources.

Several familiar foods are traditionally associated with these principles.

Pears are valued in Chinese dietary traditions for their moistening qualities.

Tremella mushroom, also known as white fungus or snow fungus, is commonly used in nourishing soups and desserts.

Lily bulb is traditionally associated with nourishing Yin and moistening the Lung.

Lotus seeds, red dates, and other ingredients may also be included in seasonal dietary preparations according to the desired balance.

The selection of ingredients should reflect the individual's constitution and the nature of the dryness pattern.

Sydney Tremella Soup: A Traditional Food for Moistening Dryness

One traditional dietary preparation for autumn is Sydney Tremella Soup, commonly made with Asian pear and Tremella mushroom.

This gentle, nourishing soup has long been enjoyed in Chinese households, especially during dry seasons.

In Traditional Chinese Medicine dietary theory, pear is traditionally associated with generating fluids and moistening dryness, while Tremella is valued for its Yin-nourishing and moistening properties.

Together, they form a familiar seasonal preparation intended to support comfort and nourishment when the body experiences mild dryness.

Traditional Ingredients

• 1 Asian pear (Sydney pear)

• 10–15 grams of dried Tremella mushroom

• 3–5 red dates, if desired

• A small amount of rock sugar, according to preference

• Water as needed

Preparation

1. Soak the dried Tremella mushroom in clean water until softened.

2. Remove the firm yellow base and divide the Tremella into small pieces.

3. Wash the pear and cut it into pieces, removing the core.

4. Place the Tremella in a pot with water and simmer gently until it becomes soft.

5. Add the pear and optional red dates.

6. Continue simmering until the ingredients are tender and the soup develops a smooth texture.

7. Add a small amount of rock sugar if desired and serve warm.

This soup may be enjoyed as part of a balanced seasonal diet.

In traditional dietary practice, it is particularly associated with nourishing fluids and moistening dryness. It should not be regarded as a universal treatment for every condition associated with dryness.

When Dryness Becomes Deeply Rooted

In Traditional Chinese Medicine, an imbalance that persists over time may become more complex.

What begins as mild seasonal dryness may, in some individuals, be accompanied by deeper patterns involving Yin deficiency, Blood Dryness, internal Heat, or disturbances in the movement of Qi and fluids.

When dryness becomes prolonged, simply adding moistening foods may not fully address the underlying pattern.

Traditional Chinese Medicine emphasizes identifying the root of the imbalance, distinguishing between excess and deficiency, and understanding which organ systems are involved.

The guiding principle is not merely to remove dryness from the surface but to restore harmony in the body's ability to generate, preserve, and distribute nourishing fluids.
