Understanding Excessive Sweating on Hands and Feet

Excessive sweating, medically known as hyperhidrosis, can affect various parts of the body, including the palms, soles of the feet, and under the armpits. While it is a natural response to rising body temperature and high emotional states, some individuals experience excessive sweating without these triggers. Even caffeine and certain medical conditions contribute to this condition.

Understanding the Mechanism

The human body contains approximately two to five million eccrine sweat glands that release fluid onto the skin surface in response to increased body temperature. This fluid evaporates, cooling the body. In contrast, apocrine sweat glands, specifically responsible for underarm sweating, are involved in the production of sweat that can lead to odour when mixed with bacteria.

Common Triggers of Excessive Sweating on Hands and Feet

Hot and Humid Weather Stress and Anxiety Caffeinated Drinks and Alcohol Hypoglycaemia (Low Blood Sugar) Medications (including painkillers, cardiovascular drugs, and antidepressants) Menopause Hyperthyroidism (Overactive Thyroid)

Effective Treatments for Excessive Sweating on Hands and Feet

For mild cases, over-the-counter scented antiperspirants can provide temporary relief, masking odour and reducing perspiration for a day or two. For more persistent cases, stronger antiperspirants containing aluminium chloride are recommended.

Dermatologists in Singapore may use Botox (Botulinum toxin) injections, which can provide temporary relief for up to six months. Another option is iontophoresis, where a low electric current is used to temporarily block sweat glands.

For severe cases, doctors may recommend a surgical procedure called endoscopic transthoracic sympathectomy. This procedure severs the sympathetic nerves that control sweat glands through a minor incision in the armpit. Patients can usually resume normal activities within a few days.

Coping Strategies for Excessive Sweating on Hands and Feet

Here are some practical steps to help manage excessive sweating:

Apply Antiperspirants: Use antiperspirants on palms and feet before bed to help reduce sweating. Avoid Triggers: Limit caffeine and spicy foods that can trigger the sympathetic nervous system. Proper Hygiene: Take daily showers but avoid saunas and hot showers to prevent rapid body temperature rise. Maintain Foot Dryness: Keep feet dry after bathing or showering to prevent bacterial growth that can cause odour. Go Barefoot: Allow your feet to air out when possible. Allow Shoes to Dry: Ensure shoes are dry and breathable before wearing them. Choose Breathable Clothing: Wear loose-fitting socks and clothing made of natural fibers to absorb moisture and allow air to circulate. Practice Relaxation Techniques: Use meditation and deep breathing to manage stress, a common trigger for excessive sweating.

Conclusion

Excessive sweating on hands and feet can be managed with various treatments and lifestyle adjustments. It’s important to identify and address underlying triggers and consider medical interventions when necessary. If you feel that your excessive sweating is affecting your daily life, consult a healthcare provider for personalized advice and treatment options.
