Direct Answer: What Is the Autumn Equinox in TCM?
The Autumn Equinox (Qiufen) marks the point of perfect balance between day and night, after which yin energy begins to dominate as days shorten. In TCM's Five Element system, autumn belongs to the Metal element, which governs the Lung and Large Intestine organs. The primary environmental pathogen of autumn is dryness, which directly attacks the Lungs — the most externally exposed organ. To stay healthy during autumn, focus on eating white, moistening foods (pears, lily bulb, lotus root, honey), practicing breathing exercises to strengthen Lung qi, protecting yourself from wind and dryness, and embracing the emotional theme of letting go. The equinox is a natural checkpoint to adjust your diet, sleep schedule, and lifestyle for the contracting energy of the season.
The TCM Framework: Metal Element and the Lungs
In TCM's Five Element theory, each season corresponds to an element, organ pair, emotion, and climate. Autumn is governed by the Metal element, which represents clarity, purity, contraction, and the ability to let go.
| Aspect | Autumn Correspondence |
|---|---|
| Element | Metal |
| Organs | Lung (Yin) and Large Intestine (Yang) |
| Emotion | Grief / Sadness |
| Climate / Pathogen | Dryness |
| Color | White |
| Taste | Pungent |
| Direction | West |
| Time of peak activity | 3:00 AM to 5:00 AM (Lung), 5:00 AM to 7:00 AM (Large Intestine) |
The Huangdi Neijing describes autumn as the season of "gathering and collecting": "In the three months of autumn, all things in nature reach their full maturity. The heavens are clear, the air is crisp. One should retire early and rise early, maintaining a calm and peaceful mind to harmonize with the autumn qi." This passage from Suwen Chapter 2 remains the foundational text for autumn living.
The Lung: The Most Vulnerable Organ
In TCM, the Lungs are called the "tender organ" because they are the most externally exposed internal organ — they connect directly to the outside air through the nose and throat. The Lungs govern qi and respiration, control the skin and body hair, and regulate the water passages. Because of this external connection, the Lungs are the first organ attacked by external pathogens like wind, cold, and especially dryness.
Autumn dryness specifically depletes Lung yin, leading to:
- Dry cough with little or no phlegm
- Dry, sore throat and dry nasal passages
- Dry, flaky skin and lips
- Thirst
- Constipation (the Large Intestine is the Lung's paired organ)
The Large Intestine: The Art of Letting Go
The Large Intestine is the Metal element's yang organ, paired with the Lungs. Its function is to eliminate waste — physically and emotionally. Autumn is the season of letting go, just as trees shed their leaves. Emotional stagnation, particularly unprocessed grief, can manifest as constipation or bowel irregularity. Supporting the Large Intestine through fiber-rich foods, adequate hydration, and emotional release practices is essential in autumn.
Actionable Steps: Autumn Wellness Practices
1. Eat White, Moistening Foods
The color white corresponds to the Metal element and the Lungs. Eating white, moistening foods is the most direct way to nourish Lung yin and combat autumn dryness:
- Pear (Li): The premier autumn fruit. Clears Lung heat, generates fluids, moistens dryness. Steamed pear with rock sugar is a classic remedy for dry cough.
- Lily bulb (Bai He): Nourishes Lung yin, calms the mind. Add to soups or congee. See our lotus seed and lily porridge recipe.
- Lotus root (Lian Ou): Clears heat, generates fluids, stops bleeding. Slice into soups or stir-fry with vinegar.
- White radish / Daikon (Luo Bo): Clears phlegm, aids digestion, resolves food stagnation. Excellent in autumn soups.
- Chinese yam (Shan Yao): Tonifies Spleen and Lung qi, nourishes Kidney yin. Steam or add to stew.
- Honey (Feng Mi): Moistens the Lungs and Large Intestine. Add to warm water or tea (never give honey to children under 1 year).
- White fungus (Bai Mu Er): Nourishes Lung yin, generates fluids. Sweet white fungus soup with rock sugar is a classic autumn dessert.

2. Practice Breathing Exercises
Autumn is the ideal time to strengthen Lung qi through breathing practices:
- Abdominal breathing: Sit comfortably, place one hand on your abdomen. Inhale slowly through the nose for 4 counts, feeling the abdomen expand. Exhale through the nose for 6 counts, feeling the abdomen contract. Practice for 5 to 10 minutes daily.
- Lung sound (Tchou): From TCM's Six Healing Sounds practice. Inhale deeply, then exhale with a "sssss" sound (like a snake) while visualizing stale air leaving the Lungs. Repeat 3 to 6 times.
- Autumn walks: Walk in clean, fresh air (especially in forests or parks) to exercise the Lungs naturally. Morning walks between 5 AM and 7 AM align with the Large Intestine meridian's peak time.
3. Protect Against Wind and Dryness
- Cover the neck: In TCM, wind enters through the neck and attacks the Lungs. Wear a light scarf in autumn, especially on windy days.
- Avoid overexposure to dry air: Use a humidifier indoors if air is dry. Keep indoor humidity between 40% and 60%.
- Stay hydrated: Drink warm water throughout the day. Add a slice of pear or a spoonful of honey for extra moistening.
- Don't sleep with windows open on windy nights: Autumn wind carries dryness-cold that can invade the Lungs during sleep.
4. Adjust Sleep Schedule
The Huangdi Neijing recommends "retiring early and rising early" in autumn. Go to bed earlier (by 10 PM) to support the body's contracting yin energy, and wake early to align with the clean, crisp morning air. This contrasts with summer's late bedtimes and winter's extra sleep.
5. Support Emotional Release
Grief is the emotion associated with the Metal element and the Lungs. Autumn naturally brings a sense of melancholy as nature contracts. Rather than suppressing this feeling, TCM encourages healthy emotional release:
- Journal about what you need to let go of — old resentments, outdated habits, or relationships that no longer serve you.
- Practice gentle Qigong or Tai Chi to move stagnant emotional energy.
- Spend time in nature observing the changing season — the falling leaves model the natural process of release.
- Deep breathing itself is an act of letting go — each exhalation releases physical and emotional tension.
Drink chrysanthemum tea with a few goji berries in autumn. Chrysanthemum clears heat from the Lungs and Liver, while goji berries nourish Liver and Kidney yin. See our chrysanthemum tea guide.
Contraindications and Precautions
- Asthma and COPD: Autumn is a high-risk season for respiratory conditions. Follow your doctor's treatment plan and use TCM practices as complementary support only.
- Cold-type cough: If your cough produces clear, watery phlegm and you feel cold, the pattern is cold-damp rather than dryness. Use warming foods like ginger tea rather than cooling, moistening pear.
- Spleen deficiency: If you have loose stools and poor digestion, eat pears and raw fruits in moderation. Steam or cook them to reduce their cooling nature.
- Allergies: Autumn allergens (ragweed, mold) can worsen Lung symptoms. Consult your allergist for appropriate management.
- Excessive pungent foods: While the pungent taste corresponds to Metal, too much spicy food in autumn can worsen dryness. Use moderate amounts of ginger, garlic, and pepper.

The Bottom Line
The Autumn Equinox is nature's invitation to contract, collect, and let go. By aligning with the Metal element — eating white, moistening foods to protect your Lungs from dryness, practicing breathing exercises to strengthen respiratory qi, adjusting your sleep schedule, and embracing emotional release — you can transition smoothly into the yin half of the year. The Lungs are tender; protect them with a scarf, hydrate with warm teas, and eat steamed pears. The Large Intestine mirrors the emotional theme of letting go — if you find yourself holding on to what no longer serves you, remember the trees shedding their leaves. Release, contract, and gather your energy inward for the colder months ahead.
