Understanding the Causes and Remedies for Excessive Sweating

Normal sweating helps regulate body temperature by releasing moisture through sweat glands. Humans have about 2 to 5 million sweat glands, with areas like hands, feet, and forehead experiencing more perspiration. The armpits contain fewer glands but tend to sweat more visibly because the moisture evaporates slowly, leading to body odor.

When body temperature rises, eccrine glands produce a watery sweat to cool us down through evaporation. Emotional stress or anxiety activates apocrine glands, causing additional sweating.

Several factors can lead to excessive sweating, including fever and tuberculosis, even when there is no apparent illness. In some cases, genetic predisposition or overactive nerve signals cause excessive sweat production, particularly on the hands, feet, and armpits.

Key causes of excessive sweating include:

Hyperthyroidism: An overactive thyroid increases metabolic rate, resulting in increased perspiration. Diagnosis involves blood tests, and treatment options include medication, surgery, or iodine therapy.

Cancer: Certain cancers can lead to excessive sweating as the body fights disease or due to treatment effects, though exact mechanisms are still under study.

Medications: Some drugs, such as psychotropics, blood pressure medications, antibiotics, and supplements, may trigger excessive sweating. Always consult your doctor before stopping any medication.

Diabetes: Blood sugar imbalances in both Type 1 and Type 2 diabetes often result in increased sweating as a symptom of metabolic disruption.

Menopause: Fluctuating estrogen levels cause hot flashes and night sweats, disrupting sleep and daily comfort.

Stress and Anxiety: Psychological factors can elevate body temperature, leading to more sweating. Substance withdrawal, like alcohol or opioids, can also cause heavy perspiration.

To manage excessive sweating, consider these tips:

Use antibacterial soaps with triclosan to prevent infections in sweaty areas.

Avoid spicy foods and exposure to heat to reduce triggers.

Apply antiperspirants regularly, especially on the armpits, to control odor and sweat.

Wear breathable clothing like cotton instead of synthetic fabrics.

Utilize sweat shields to absorb moisture and prevent stains.

Apply aluminum chloride-based antiperspirants overnight for best results.

Clean sweat-prone areas thoroughly, then use sodium chloride to help reduce sweating over time.

If excessive sweating persists, consult a dermatologist for diagnosis and tailored treatment options.
