Understanding Perspiration: Triggers, Normalcy, and Medical Concerns

Perspiration (sweating) is the body's primary cooling mechanism. It occurs in response to:

• Heat exposure (environmental or metabolic)
• Physical exertion
• Emotional stress (sympathetic activation)
• Hormonal changes (menopause, thyroid disorders)

Hyperhidrosis (excessive sweating beyond thermoregulatory needs) may be primary (idiopathic, focal) or secondary to medical conditions (infections, malignancies, medications, endocrine disorders). If sweating disrupts daily life, occurs at night, or is accompanied by other symptoms, medical evaluation is warranted.
