Hyperhidrosis is excessive sweating far beyond what the body needs to do normally
to control our body temperature.
Everyone sweats to some extent. This is an important process to help the body to
control its temperature and hydrate the skin. It is usually tightly controlled so
that just enough moisture is released which will then evaporate from the surface
of the skin. This action helps to keep us cool. We sweat more when exercising and
this can result in our bodies becoming damp because the moisture cannot evaporate
Excessive sweating results in moisture laying on the surface of the skin instead
of evaporating like it normally would. For people with hyperhidrosis this causes
them problems with needing to wash more frequently and change wet clothes, sometimes
several times a day. It can occur on any part of your body but most often is found
under your arms, on the palms of hands, soles of feet, forehead and upper lip and
trunk of the body.
For most people the usual causes of sweating might be exercise, some foods, especially
spicy foods, types of clothing and possibly stress. For those suffering from hyperhidrosis
there may be no apparent trigger to their increased sweating. Indeed, someone with
hyperhidrosis is just as likely to sweat too much when it is cold as when it is hot
and stress is not normally a trigger.
