什麼是手汗症？
自主神經系統分成交感和副交感神經系統，而人的汗腺是由交感神經系統所支配。手掌多汗症（Palmar Hyperhidrosis ）乃因交感神經功能亢進引起，導致兩側手掌流汗量比正常人多且異常。
What
is the cause of Palmar Hyperhidrosis (excessive sweating of the hands)?
The autonomic
nervous system is divided into the sympathetic and parasympathetic nervous
system. The sweat glands are predominantly controlled by the sympathetic
nervous system. Excessive hand sweating is caused by hyperfunction of the
sympathetic nervous system.
