What is sweating?
Sweating occurs when the sweat glands in your skin secrete a salty fluid
called sweat, or perspiration. Sweating is a normal function that serves to
cool your body, often in hot or humid environments or when you exercise. How
much you sweat depends on how many sweat glands you have. A person is born with
about two to four million sweat glands which start to become fully active
during puberty. Sweating is controlled by the autonomic nervous system, the
part of the nervous system that is not under your control.
Women have more sweat glands then men, but men's
glands are more active.
Sweating is the body's natural way of regulating temperature.People
sweat more when it's hot outside, when they exercise, or in response to
situations that make them nervous, angry, embarrassed, or afraid. Sometimes
however sweating can become excessive.
Excessive Sweating
Excessive sweating means that you sweat much more than normal, even when
you are not hot, anxious, or exercising, you make a lot of sweat. It can
infringe on daily life and can be extremely distressing for sufferers
Reasons for Excessive Sweating
Primary Focal Hyperhidrosis (PFH) - This is the most common
cause of excessive sweating and affects about 1% to 3% of the population, it
usually starts in childhood or adolescence. Primary focal hyperhidrosis does
not cause illness. Basically, you sweat excessively. Although it is a medical
condition, it's not a sign of disease or a drug interaction. People who have it
are otherwise healthy. The symptoms of PFH are fairly specific. It's called
focal or localised because it only affects specific parts of the body, such as
the underarms, groin, head, face, hands, or feet. Symptoms also tend to be
symmetrical, occurring on both sides equally.Experts aren't sure exactly why
this happens, but it seems to stem from a minor malfunction in the nervous
system. There's some evidence that it could run in families.
Secondary General Hyperhidrosis - This less common form of
hyperhidrosis causes sweating all over the body -not just on the hands or feet.
Secondary general hyperhidrosis is also more serious medically. It's called
secondary because it's being caused by something else, such as an underlying
health condition.One telltale sign of secondary hyperhidrosis is excessive
generalised sweating at night.
There are many possibilities and medical conditions
and diseases which can cause this including
- Menopause
- Pregnancy
- Thyroid problems
- Diabetes
- Alcoholism
- Infectious diseases like tuberculosis
- Parkinson's disease
- Rheumatoid arthritis
- Stroke
- Heart failure
- Cancers like leukaemia and lymphoma
Other Causes of Sweating
- Anxiety - People who are anxious or have actual anxiety disorders may sweat more than others. But experts say that anxious sweating isn't the same as hyperhidrosis.
- Medications - Medications can also cause general excessive sweating, such medications are
- Some psychiatric medications
- Some blood pressure medications
- Some medicines for dry mouth
- Some antibiotics
- Some supplements
Treating Excessive Sweating
While there is no cure for PFH, there are ways to help
control the symptoms. They include:
Antiperspirants - Special
over-the-counter or prescription sprays, lotions, and roll-ons can help control
symptoms.
Iontophoresis - This treatment uses
low-level electrical impulses to temporarily disable the sweat glands.
Medications - Some drugs can stop the sweat glands from kicking
into action.
Botox - Injections of Botox can temporarily stop the nerves from triggering
excessive sweating. It is approved for treatment of excessive underarm
sweating.
Surgery - One approach is to cut a nerve in the chest that
triggers excessive sweating. Another is to surgically remove some of the sweat
glands.
Secondary hyperhidrosis can often be treated too,
although the right approach depends on the condition causing it.
Alternative Options for Excessive Sweating
Drink more water - A lot of people are confused by this solution. They
think if they drink more water, it will give them that much more fluid to sweat
out. This is totally incorrect. Drinking more water cools your core temperature
and will alleviate some of the excessive sweating.
Drink Green Tea or Sage Tea at night – These teas contain an astringent
property which will dry out oils and prevent excess moisture from escaping the
skin. It basically dries you from the inside out. In addition to helping your
complexion, green tea will neutralise many of the toxins that create the
pungent odour in sweat.
Avoid spicy foods, alcohol and caffeine - Onions, Garlic, Curry, Coffee and
a whole host of other ingredients are powerful triggers for hyperhidrosis
sweating. Cut out some of these culprits and see gradual but noticeable
results.
Sage Leaf Supplement - It is well documented that Sage leaf helps to
reduce menopausal sweats. In one study, excessive sweating was induced by
medication The sweating was reduced when participants were given an extract of
sage leaf. In a further study 40 patients were given dried aqueous extract of
fresh sage (440mg) and 40 were given infusion of sage (4.5g) herb daily. Both
groups of patients experienced a reduction in sweating.
