Sweating Every Time You Step into the Office? Tips to Overcome 'Stress-Induced Hyperhidrosis'

How does modern medicine explain this emotional sweat? While Korean medicine views the heart as the command center of the mind, modern medicine attributes this role to the autonomic nervous system. The autonomic nervous system is divided into sympathetic and parasympathetic nerves. Balancing each other like a seesaw, they form a regulatory system that governs heartbeat, digestion, and sweat secretion independent of our conscious control.

When confronted with stress or tension, the body signals a fight-or-flight state and activates the sympathetic nerve. The hypothalamic-pituitary-adrenal axis engages, releasing stress hormones such as cortisol and adrenaline to prepare the body for action. As the heartbeat quickens and blood pressure rises, acetylcholine, a neurotransmitter that stimulates sweat glands, is released in large quantities to trigger perspiration. This reaction cools the body and prepares it to face acute demands.

Problems arise when this stress response occurs repeatedly and chronically. Excessive sympathetic activation disrupts the balance with the parasympathetic nerve, leaving sweat glands hypersensitive to minor stimuli. This reaction is particularly pronounced in areas densely populated with eccrine sweat glands that receive strong sympathetic input, such as the palms, soles, armpits, and face. Anticipatory anxiety, where the thought of sweating triggers actual perspiration, often creates a persistent cycle. Extending beyond physical discomfort, it can disrupt professional routines and personal interactions, lowering quality of life and calling for attentive care.
