Autumn According to Chinese Medicine: Grief, Letting Go, and Preparing for Change

Read Time 11 Minutes

Research now confirms what Chinese medicine has understood for over 2,000 years: grief and unprocessed loss have measurable effects on the immune system. Bereaved individuals exhibit evidence of reduced antibody response to vaccination, elevated cortisol levels, heightened systemic inflammation, and impaired immune responses, including reduced functional activity of natural killer cells. In other words, what we carry emotionally shows up physically. And autumn, in TCM, is exactly the season when the body is most primed to release what it has been holding.

Most of us experience autumn as a time of change: back-to-school schedules, shorter days, the first cold in the air. But in the framework of seasonal living, it is something more specific. It is the season of completion, of refinement, and of conscious release — physically and emotionally. The Lungs are asking for more attention. The unprocessed grief is asking to move. And the body, if you listen to it, knows exactly what to do.

If any of this connects to something deeper you are carrying — old loss, stored stress, or patterns of emotion that feel stuck in the body — our post on Healing Trauma Through Body and Spirit explores this territory in a way that pairs closely with what we cover here.

For now, let’s start with what autumn actually is in Chinese medicine.

Why Autumn Belongs to the Metal Element

Contraction, Refinement, and the Energy of Completion

Every season in Traditional Chinese Medicine corresponds to one of the Five Elements. Autumn belongs to Metal.

Metal energy is different from the upward surge of Wood in spring or the expansive heat of Fire in summer. Metal moves inward and downward. It contracts, refines, and distills. Think of how autumn in nature works: the tree draws its energy down from the leaves into the roots. What is no longer needed falls away. What is essential gets stored for winter.

That is the quality autumn asks of us, too. This is the season to finish things rather than start them, to simplify rather than expand, and to honestly assess what we are still carrying that no longer belongs with us.

In Chinese medicine, autumn is governed by the Lungs and Large Intestine. These two organ systems together form the Metal element pair, and they share a surprisingly unified purpose.

The Lung and Large Intestine: One System, Two Functions

Most people understand the Lungs as the organs of breathing. In TCM, they carry a larger role: they govern the intake of pure Qi from the air, they regulate the body’s defensive energy (Wei Qi), they manage the skin as a surface organ, and they descend energy downward through the body to keep everything moving in the right direction.

The Large Intestine is the Lung’s partner in this process. Its job is to release: physically eliminating what the body no longer needs, and energetically doing the same. When these two organs work together well, there is a natural rhythm of intake and release, of holding what is nourishing and letting go of what is not.

When either one is compromised, that rhythm breaks down. And in autumn, the season when both organs are most active and most sensitive, that breakdown becomes most visible.

Organ	Physical Function	Emotional Function
Lungs	Breath, Qi intake, immunity, skin	Receiving inspiration, processing grief
Large Intestine	Eliminating physical waste	Releasing emotional stagnation, letting go

Grief as Medicine: Understanding Autumn’s Emotion

Grief Is Not Just Sadness

Every season in Chinese medicine carries its own emotional signature. Autumn’s is grief. But the way TCM uses that word is broader than most people expect.

Grief here is not limited to the kind that follows a death. It includes the quiet sadness of things ending, the loss of a version of yourself you grew out of, the feeling that something important slipped by before you had a chance to fully appreciate it, the heaviness that comes with big transitions, even good ones. It includes the emotional residue from relationships that changed, chapters that closed, and seasons of life that passed faster than you were ready for.

In other words, most adults are carrying some form of grief most of the time. And most of us have learned to keep moving through it rather than actually moving through it.

Healthy Grief vs. Suppressed Grief

Chinese medicine makes an important distinction between grief that moves and grief that stays.

When grief is allowed to move through you, it does what it is supposed to do: it honors the loss, processes the change, and then releases. You feel sad, you express it somehow, and eventually you feel lighter. The Lungs can breathe more deeply. The body relaxes. The immune system, which had been under strain, begins to recover.

When grief is suppressed, it doesn’t disappear. It settles. TCM has always described the Lungs as the organ where held grief lives in the body. Modern research is increasingly confirming this: key findings in pathological grief reactions include altered cortisol rhythms, elevated oxytocin levels, increased pro-inflammatory cytokines, and immune system dysregulation. The body holds what the mind tries to move past.

Healthy Grief Expression	Suppressed Grief Patterns
Sadness that comes and goes in waves	Flat, numb emotional state most of the time
Ability to cry and feel relief afterward	Difficulty crying or emotion that feels stuck
Energy recovers after the grieving period	Persistent fatigue that doesn’t improve with rest
Clear breathing, open chest	Shallow breathing, tight chest, frequent sighing
Seasonal transitions feel manageable	Seasonal changes feel disproportionately hard
The immune system remains reasonably strong	Frequent colds, low immunity, and recurring illness

💡 Worth noticing: If you find yourself sighing frequently and can’t explain why, TCM considers this a direct sign of the Lungs trying to release suppressed grief. The body is doing what it can on its own. Supporting it consciously makes the process considerably easier.

When Grief Gets Stored in the Body

This is the part that most autumn wellness articles skip entirely. Grief that goes unprocessed doesn’t just affect your mood. It affects your lungs, your immune function, and your overall resilience going into winter.

In clinical practice, patients who arrive in autumn already depleted from a year of emotional stress, change, or loss are consistently more susceptible to respiratory illness in the months that follow. This is not a coincidence. It reflects exactly what TCM has mapped for thousands of years: the Lung-grief-immune connection is a causal chain, not a metaphor.

If you are carrying grief or emotional weight from the past year, including the everyday kind from difficult transitions, relationship changes, or simply the accumulated stress of living, autumn is the most efficient season to address it. The body’s energy is already moving in the direction of release. You are working with a current that is already flowing, not against one.

If your grief feels larger than seasonal support can reach, the work we explore in Healing Trauma Through Body and Spirit goes into the deeper body-based approaches that help stored emotion actually move.

What Happens When Grief Goes Unprocessed

The Lung-Grief-Immune Connection

The connection between emotional suppression and physical illness is one of the most well-documented areas in modern psychoneuroimmunology, and it maps almost exactly onto what TCM described in its classical texts.

When grief or emotional stress is held chronically in the body, cortisol levels rise and remain elevated. Cortisol showed a weak negative correlation with lymphocyte percentage, suggesting a potential reduction in immune responsiveness with elevated cortisol levels. In simple terms: the more stress hormones circulating, the less effectively your immune system can do its job. And autumn, with its transition into cold and flu season, is exactly when you need your immune defenses at their strongest.

TCM describes this as Wei Qi (defensive energy) becoming weakened by the Lung’s burden of held grief. When the Lungs are occupied carrying unexpressed emotion, they have less capacity to protect the body at its surface — the skin, the mucous membranes, the respiratory tract. The result is a person who catches every cold that goes around, who takes longer to recover, and who arrives at winter already depleted.

Supporting your emotional health in autumn is not separate from supporting your physical immunity. In Chinese medicine, they are the same work.

Signs Your Lungs Are Carrying More Than Air

How do you know if your Lung energy needs autumn support? Here are the signs worth paying attention to:

• Shallow breathing or a frequent feeling of not being able to take a full breath
• Recurring respiratory issues: colds, sinus congestion, dry cough that lingers
• Dry skin that worsens significantly in autumn regardless of hydration
• A low-grade sadness or sense of melancholy that you can’t quite locate
• Difficulty letting go of things: physically (clutter, old items), relationally (past hurts), mentally (overthinking completed situations)
• Grief or loss from earlier in the year that you haven’t fully acknowledged or processed
• Feeling emotionally flat or numb rather than genuinely sad

If several of these feel familiar, your Metal element is asking for attention this season.

The Art of Letting Go: What It Actually Requires

Letting Go Is a Physical Act, Not Just a Mindset

This is where most autumn advice misses the mark. “Let go” gets said as if it’s simply a decision you make. In reality, letting go is something the body has to be resourced and supported enough to actually do. You cannot think your way out of emotional patterns that are stored in the body. You have to move them through the body.

Deep, conscious breathing is the most direct physical tool for this. The Lungs literally release what is no longer needed with every exhalation. Expanding that exhalation, consciously lengthening it beyond what feels automatic, initiates the body’s relaxation response, lowers cortisol, and physically signals the nervous system that it is safe to release what it has been holding.

This is not breathing as exercise. It is breathing as medicine. Five to ten minutes of slow, deliberate breathing where the exhale is at least twice as long as the inhale can measurably shift the body’s state within a single session.

The Large Intestine’s Role in Release

The Large Intestine in TCM is understood as the organ of physical and emotional letting go. When it is functioning well, the body eliminates what it no longer needs efficiently and completely, both physically and energetically. When it is compromised, things stagnate.

In clinic, over thirty years of practice, one of the most consistent patterns we see in autumn is the combination of emotional holding and digestive sluggishness. The two systems are linked. When people begin supporting their Large Intestine through warming, fiber-rich autumn foods and movement, they often describe a simultaneous shift in their emotional state: a sense of things loosening, of being slightly lighter, of it becoming easier to let go of thoughts and feelings that had felt stuck.

This is not accidental. The body is one system. Supporting the physical releasing capacity of the Large Intestine genuinely supports the emotional releasing capacity of the Metal element.

How to Support Your Lungs and Emotional Wellbeing This Autumn

Breathing Practices That Actually Work

The single most important thing you can do for your Lungs in autumn costs nothing and takes five minutes.

Extended exhalation breathing: Inhale slowly for four counts, exhale for eight counts. Repeat for five to ten minutes daily, ideally in the morning in fresh outdoor air if possible. This directly strengthens Lung Qi, supports the body’s natural releasing process, and activates the parasympathetic nervous system.

Gentle chest-opening movement: Qi Gong practices that open the chest and expand the ribcage are specifically designed to free constrained Lung energy. Even simple arm circles combined with deep breathing can shift how the Lungs feel after a few minutes.

Spending time outdoors in cool, fresh air: The Lungs are nourished by clean, crisp air. Autumn’s cool, clear air is genuinely medicinal for this organ system. Daily walks in fresh autumn air, particularly in nature, directly support Lung health in a way that indoor environments cannot replicate.

Foods That Nourish Lung Health in Autumn

Autumn calls for a dietary shift: away from the cooling, raw foods of summer and toward warming, moistening, cooked foods that protect the body as the air turns drier and cooler.

Pungent foods are the flavor associated with the Metal element. Small amounts of pungent foods gently stimulate Lung function and help clear congestion: garlic, ginger, radish, daikon, and spring onion all belong here.

White foods correspond to the Metal element and directly support the Lungs: pear (especially cooked with honey, a classical TCM remedy for dry Lung), white fungus (tremella mushroom), lotus root, and cauliflower.

Warming and moistening: Soups, broths, congee, roasted root vegetables, and cooked whole grains all create the internal warmth and moisture that protect the Lungs against autumn dryness. This is the season to rediscover cooking as a nourishing practice. Our post on Why Cook at Home covers this beautifully.

What to reduce: Cold, raw, and heavily processed foods dry out the Lungs and weaken Wei Qi. Dairy in excess can increase mucus production. Alcohol depletes Lung Yin. These are worth reducing progressively through autumn, not necessarily eliminating, but consciously scaling back.

Acupuncture and Herbal Support

For people dealing with persistent respiratory weakness, recurring autumn illness, low immunity, or emotional patterns that feel genuinely stuck, acupuncture and herbal medicine offer more targeted support.

Key acupoints for the Lung system in autumn include Lung 7 (LU7), which opens the Lungs, supports the immune surface, and is particularly indicated for grief and emotional release; and Large Intestine 4 (LI4), which supports the body’s releasing function across both the physical and emotional dimensions.

The clinical research on acupuncture for respiratory health is substantial and growing. A 2024 systematic review and meta-analysis published in PMC evaluated acupuncture for dyspnea and breathing physiology across multiple randomized controlled trials in patients with chronic respiratory diseases, finding meaningful clinical applications across conditions including COPD, asthma, and lung cancer. A 2025 multicenter randomized controlled trial published in Complementary Therapies in Medicine involving 150 patients confirmed statistically significant improvements in respiratory outcomes for COPD patients receiving acupuncture, with both time and group effects reaching significance at p less than 0.05.

For herbal support, Yu Ping Feng San (Jade Windscreen Powder) is the classical formula for strengthening Wei Qi and reducing susceptibility to seasonal illness. Bai He Gu Jin Tang (Lily Bulb Decoction to Preserve Metal) nourishes Lung Yin and is particularly suited to the dry, depleted Lung patterns common in autumn. Both should be used under the guidance of a qualified TCM practitioner based on your specific pattern.

Closing Thoughts

Autumn is not just a beautiful season. It is a biological instruction. The trees are not losing their leaves — they are choosing what to keep. They are drawing their energy inward, releasing what has served its purpose, and preparing the resources that will carry them through winter and into spring. Your body is being asked to do the same. When you give it the support to do that — through breath, through nourishing food, through honest emotional acknowledgment, and through the skilled support of acupuncture and herbs where needed — you move through this season rather than just surviving it. And what waits on the other side of that release is not emptiness. It is space. And space is exactly what a good winter rest needs to fill.

Frequently Asked Questions

Why does Chinese medicine associate autumn with grief and the lungs?

In TCM’s Five Element framework, autumn corresponds to the Metal element, which governs the Lungs and Large Intestine. Grief is the emotion associated with this element because the Lungs are understood as the organ that processes emotional intake and release, just as they process air. When grief is expressed and allowed to move through the body, the Lungs function well, and immunity remains strong.

How does suppressed grief affect immune health in autumn?

Research confirms that unprocessed grief and prolonged emotional stress elevate cortisol levels, which reduce immune responsiveness by lowering lymphocyte activity and impairing the function of natural killer cells. In TCM terms, this is the grief burden weakening Wei Qi, the body’s defensive energy that lives at its surface and protects against seasonal pathogens. 

What does “letting go” actually mean in Chinese medicine?

In TCM, letting go is not just a mindset shift. It is a physical process that the Lungs and Large Intestine facilitate together. The Lungs release on every exhalation. The Large Intestine releases physical and emotional waste through elimination. When both organ systems are supported, the body’s natural releasing capacity increases.

What foods does Chinese medicine recommend for lung health in autumn?

TCM recommends warming, moistening, and mildly pungent foods for lung health in autumn. Key recommendations include pear (especially cooked with honey), white fungus mushroom, lotus root, daikon radish, garlic, ginger, soups, broths, congee, and roasted root vegetables. The shift is from the cooling raw foods of summer toward cooked, warming foods that protect the body against autumn dryness and support the Lung’s immune function.

How can acupuncture support lung health and emotional wellbeing in autumn?

Acupuncture supports the Lung system in autumn by strengthening Wei Qi, opening the respiratory passages, supporting the body’s releasing function, and addressing the emotional patterns held in the Metal element. Clinical research published in PMC in 2024 found meaningful applications of acupuncture for chronic respiratory disease management, and a 2025 multicenter RCT confirmed statistically significant improvements in respiratory outcomes for patients receiving acupuncture.
