🔍 Quick Summary

Excessive or unusual sweating may signal an underlying condition.
1️⃣ Introduction
Sweating is the body’s way of cooling itself.
• occurs with heat, exercise, or stress

👉 Not all sweating is abnormal—but patterns matter.
2️⃣ How it happens
Sweat glands are controlled by the nervous system.
• body temperature rises → sweat glands activated
• sweat evaporates → cools the body
• nerves regulate the amount of sweating
👉 Overactivity of this system can lead to excessive sweating.
3️⃣ Types
• Primary (focal) sweating
- affects specific areas (hands, feet, armpits)
- often starts early in life

- affects the whole body
- may be due to medical conditions
