Spontaneous sweating

Also called:daytime sweatingexcessive sweating

From the TCM perspective: Spontaneous sweating (zìhàn): insecure defensive qi

Overview

Spontaneous sweating is excessive daytime perspiration without heat or exertion, worsening with activity. TCM mainly attributes it to qi/yang deficiency with insecure defensive (wei) qi failing to close the pores; disharmony of ying-wei or damp-heat may also cause it.

☯Common patterns (syndrome differentiation)

Insecure lung-defensive qi

Key distinguishing signs: Sweating with mild fear of wind, frequent colds, fatigue, worse after exertion, pale tongue and weak pulse
Treatment principle: Tonify qi and consolidate the exterior to stop sweating

Yang deficiency

Key distinguishing signs: Cold sweat, cold limbs, intolerance of cold, pale face, early-morning diarrhea, pale moist tongue and deep slow pulse
Treatment principle: Warm yang and tonify qi to secure the exterior

Disharmony of ying and wei

Key distinguishing signs: Sweating with wind intolerance, intermittent mild fever, generalized aching, moderate floating pulse
Treatment principle: Harmonize ying and wei and release the muscle layer

Damp-heat steaming

Key distinguishing signs: Sticky yellow odorous sweat, heavy sensation, bitter sticky mouth, dark urine, yellow greasy tongue coat
Treatment principle: Clear heat and drain dampness, promote qi movement

Daily self-care

Avoid direct drafts after sweating and change damp clothes promptly.
Use warming foods (yam, rice, dates) for qi deficiency; avoid hot, fried and greasy food for damp-heat.
Exercise moderately without overexertion and sleep well to support defensive qi.
