Excessive perspiration of the feet

Excessive perspiration of the feet is often a taboo subject. It can become embarrassing, and even get in the way of certain activities. It’s not always easy to identify its causes, but solutions do exist for limiting plantar hyperhidrosis.

What is plantar hyperhidrosis?

Although sweating is a natural physiological phenomenon, it can become troublesome if it becomes excessive. Oversweating on the soles of the feet is a symptom of excessive perspiration, called plantar hyperhidrosis.

Excessive perspiration of the feet is characterized by a hyperactivation of sweat glands. It is these glands, located under the skin, that secrete sweat.

What causes plantar hyperhidrosis?

The causes of oversweating of the feet have not yet been clearly identified. However, certain factors and certain situations are known to trigger sweating of the feet:
  • Intense physical activity
  • Wearing of totally airtight shoes (rubber soles, boots, etc.) that do not allow feet to breathe
  • Wearing of nylon socks or stockings, which encourage sweating
  • Poor foot hygiene

What are the consequences?

Excessive perspiration of the feet results in maceration. This softens the corneal layer and can cause bacterial infections, skin mycoses and even wounds.

Moreover, plantar hyperhidrosis is often accompanied by bromhidrosis, i.e. foul smelling feet. This phenomenon is explained by the decomposition of the organic matter present in sweat and by the proliferation of bacteria and fungi.

What can I do?

Excessive perspiration of the feet is a phenomenon that can be particularly troublesome. Fortunately, there are solutions.

To prevent plantar hyperhidrosis, it is first recommended to:
  • Wash feet regularly: once or several times a day if necessary, paying special attention to drying them well, without forgetting the interdigital folds to avoid maceration caused by a humid environment
  • Change socks once or several times a day and opt for natural materials that allow skin to breathe
  • Use insoles with absorbent properties that can be removed and therefore easily washed
There are lots of solutions available in pharmacies for limiting the sweating phenomenon and for getting rid of odors: astringent solutions and powders (talc), antiperspirant products containing aluminium salts (lotions, creams), soaking solutions containing an antibacterial agent, etc.

If, despite these preventive measures, plantar hyperhidrosis persists, you should consult a health professional to find an appropriate solution.
