Hot Flashes & Night Sweats

Also called:Hot flashesHot flushesNight and day sweats

From the TCM perspective: TCM perimenopausal disorders / tidal fever; rooted in the kidney, involving heart and liver.

Overview

Hot flashes and sweating are episodic waves of heat in the face and body with perspiration, common in perimenopause but also in other states of yin-yang imbalance. TCM holds that around age 49 the tiangui is exhausted; kidney yin deficiency is the root, with liver constraint transforming to fire, damp-heat, or yin-yang/construction-defense disharmony.

Daily self-care

Dress in layers and carry a change of clothes; keep rooms cool, exercise regularly and manage weight.
Track triggers (spicy food, hot drinks, alcohol, stress, heat) and avoid them; slow breathing can reduce episodes.
If symptoms disrupt sleep and daily life, seek a gynecology/menopause assessment; quitting smoking also reduces hot flashes.

When to seek medical help

The following warning signs require prompt medical evaluation — do not rely on self-treatment:

Periods stopping before age 40 with hot flashes or symptoms: evaluate premature ovarian insufficiency.
Hot flashes with persistent fever, night sweats or marked weight loss: prompt evaluation for other disease.
Chest pain, palpitations, severe low mood or self-harm thoughts: seek care promptly.
