Irritability may be caused by stress, fatigue, hormonal changes, chronic pain, sleep disturbances, or underlying health conditions such as anxiety, depression, thyroid disorders, and nutritional deficiencies.
Just like physical health, maintaining mental health requires early action. Early signs such as low mood or depression, irritability and frustration, insomnia or difficulty sleeping, loss of appetite, and persistent fatigue should not be ignored.

Kampo’s Perspectives on Irritability
1. Liver Qi Stagnation
In Kampo, irritability is most commonly attributed to Liver Qi stagnation, where the flow of Qi becomes obstructed due to stress, frustration, or emotional suppression. This can lead to symptoms such as mood swings, chest tightness, frequent sighing, and a feeling of fullness in the chest or abdomen.
- Western Medicine Link – In Western medicine, irritability and mood swings related to stress are often linked to chronic activation of the stress response. Emotional suppression and ongoing frustration can stimulate the sympathetic nervous system, leading to muscle tension, shallow breathing, chest tightness, and hormonal imbalances involving cortisol and serotonin—key regulators of mood.
These physical and emotional reactions resemble the manifestations of Liver Qi stagnation in Kampo theory.
2. Liver Fire
When Liver Qi stagnation progresses, it can generate internal heat, resulting in Liver Fire rising. This pattern is associated with more intense irritability, sudden outbursts of anger, a flushed face, headaches, a bitter taste in the mouth, and sensations of heat in the upper body.
- Western Medicine Link – Symptoms like sudden anger, flushed face, headaches, and upper body heat may be associated with autonomic nervous system dysregulation and stress-related hypertension. Intense emotional stress can trigger sympathetic overactivation, leading to elevated blood pressure, vascular dilation in the face and head, and stress-induced headaches.
These reactions, often seen in individuals with poor emotional regulation or chronic frustration, closely mirror the Kampo concept of Liver Fire rising.
3. Spleen Qi Deficiency
In Kampo, the Spleen is responsible for producing Qi and Blood by transforming food and drink into energy. After childbirth, the strain of delivery, breastfeeding, irregular meals, and poor recovery can weaken the Spleen. This may lead to persistent fatigue, poor appetite, easy bruising, muscle weakness, and a sense of being mentally and physically worn out.
- Western Medicine Link – In Western medicine, this symptom pattern may correspond to stress-related fatigue, burnout, or generalized anxiety disorder. Chronic mental strain and emotional overload can disrupt the hypothalamic-pituitary-adrenal (HPA) axis, leading to sleep disturbances, fatigue, digestive issues, and impaired cognitive function such as poor concentration. Palpitations and irritability may also result from autonomic imbalance.
These effects align with the Kampo view of Heart and Spleen deficiency, where overwork depletes mental and physical reserves.
4. Blood Deficiency
Blood deficiency is another underlying pattern where the mind and spirit lack sufficient nourishment. In this case, irritability is often accompanied by emotional hypersensitivity, insomnia, dizziness, paleness, and dry skin, reflecting a broader depletion of vitality.
- Western Medicine Link – In Western medicine, this pattern resembles iron-deficiency anemia, where reduced red blood cell levels lead to fatigue, irritability, dizziness, pale skin, and insomnia. Emotional sensitivity and poor concentration may result from low oxygen delivery to the brain.
These signs reflect overall depletion, similar to Blood deficiency in Kampo, where the mind and body lack proper nourishment.
5. Yin Deficiency with Empty Heat
Chronic irritability may also arise from Yin deficiency, where the body’s cooling and moisturizing functions are impaired, leading to the development of internal heat. This results in irritability alongside symptoms such as night sweats, dry mouth, low-grade fever sensations, and a thin, dry body constitution.
- Western Medicine Link – In Western terms, this pattern resembles conditions involving autonomic dysregulation, perimenopausal changes, or chronic stress-induced inflammation. Symptoms like night sweats, dry mouth, low-grade heat sensations, and irritability may relate to hormonal imbalance (e.g., estrogen decline) and nervous system overactivity.
This mirrors the Kampo concept of Yin deficiency, where internal cooling is weakened, allowing heat and restlessness to rise.
