In Traditional Chinese Medicine (TCM), psoriasis is considered to be related to a combination of factors, including internal imbalances and external environmental influences. It is recommended to address the condition holistically, combined with lifestyle modifications.

1. Internal constitution factors: Traditional Chinese medicine believes that some people are born with a constitution that is prone to heat or blood stasis, which easily generates internal heat and affects skin health.

2. Emotional impact: Long-term emotional tension and excessive stress may lead to poor blood circulation, thereby aggravating or triggering skin problems.
3. External environmental stimuli: Wind, cold, or damp environments may invade the skin surface and affect normal skin metabolism.
4. Dietary and lifestyle habits: Preference for spicy and greasy foods, excessive drinking, or irregular work and rest may contribute to damp heat in the body.
In daily life, it's important to maintain emotional stability and avoid overwork; a light diet is recommended, with adequate intake of fresh fruits and vegetables; adjust clothing according to weather changes to minimize skin irritation. If symptoms are severe, it's advisable to consult a professional Traditional Chinese Medicine (TCM) practitioner for diagnosis and treatment.
