Sweat is the body’s way of regulating temperature and has many health benefits. However, many people suffer from excessive perspiration, also called hyperhidrosis, which can be uncomfortable, socially awkward and embarrassing. For some, profuse sweating can negatively impact on their everyday life to affect their emotional wellbeing and self-esteem.
The miraDry is a recent innovation in the treatment of axillary hyperhidrosis (underarm sweating). This revolutionary new technology uses electromagnetic energy to eliminate sweat glands, providing a lasting solution to excessive sweating.
Why do we sweat?
Whether the extra heat comes from physical exercise, over-stimulated nerves due to stress, consuming hot food or drink, or from high air temperatures, sweating is the body’s way of naturally regulating its temperature. As the water in the sweat evaporates, the surface of the skin cools.
Perspiration is mainly water but also contains salt (sodium chloride) as well as traces of ammonia, calcium, chloride, copper, lactic acid, phosphorus and potassium. These substances, called electrolytes, help to regulate the balance of fluids in the body.
There are two types of sweat glands. The eccrine glands, which people are born with, are the most numerous. They are found everywhere in the body but mostly in the forehead, palms and soles of the feet. The apocrine glands develop at puberty and are concentrated in the armpits and pubic region. The sweat from the apocrine glands is thicker than that produced by the eccrine glands and can be triggered by emotions.
Sweat itself is odourless. It’s the bacteria that live on the skin and break down the sweat that can cause an unpleasant odour.
miraDry, the new treatment for hyperhidrosis
The miraDry is a non-invasive, in-clinic treatment that uses precisely-controlled electromagnetic energy to eliminate underarm sweat glands. These destroyed sweat glands are not believed to grow back after treatment, so results are long lasting – and immediate.
Clinical data shows the average sweat reduction after miraDry treatment is 82 percent, with a patient satisfaction rate of 90 percent.
For best results, a three-month follow up is planned and some patients may then benefit from a touch-up procedure though most will not require it. The treatment itself is painless due to local anaesthesia and usually requires no downtime.
