Sweating – are you drinking too much water?

miraDry is a non-invasive procedure for the treatment of underarm sweating (hyperhidrosis) and sweating with odour (bromhidrosis).

It is a safe, effective and lasting treatment option that uses electromagnetic energy to permanently destroy the sweat glands.

However, if you are bothered by excessive sweating, it may be that you simply need to make a few tweaks to your lifestyle.

Drinking fluids and sweating

One of the biggest problems we see with people thinking that they have a problem with excessive sweating is the number of them who have listened to bad advice given by companies selling bottled water or members of the beauty and fitness industry who also earn money by selling water.

It is quite common for people to be told that they need to drink 2 or 3 litres of water a day and are often told this to ‘detox’ or to keep their skin healthy. In fact, it is excessive water which can cause problems with metabolites in the blood leading to lack of concentration and irritability as well as excessive sweating.


most people only need 1 litre of water a day

A normal 70kg person needs 1.5 litres of water a day, which includes all of the water hidden in food, tea, coffee, fruit juice, squash, wine, beer etc. We generally have approximately 0.5 litres of water hidden in our food and so most people only need 1 litre of water a day which includes that found in beverages (see above).

If you go to the gym, or play sport, you may need to add another amount to this but it is rarely more than 0.2 to 0.5 litres.

Therefore people who eat and drink normally and then have another 2 or 3 litres of water on top of this are massively over-drinking. It is not uncommon for some people to have 4 to 5 litres per day and not surprisingly, they sweat excessively.

The simple way to check whether you are drinking too much is to look at your urine. Unless you are eating or drinking things that colour your urine, such as high protein food or drinks, beetroot etc. then most normal people’s urine should be yellow. If your urine is clear, you are almost definitely over-drinking and will be sweating excessively due to your own drinking habits and not due to hyperhidrosis. You will often be able to get rid of most of your sweating problems by drinking normally.

Other reasons we sweat

Other causes of normal but excessive sweating include people who are very fit and who exercise regularly. They tend to have a raised metabolic rate and often sweat easily and more than normal people. This is not hyperhidrosis but is merely normal excessive sweating.

In addition, people who are overweight or who dress inappropriately with many layers and very warm clothes in conditions where they are not needed, can force themselves to sweat excessively which again is normal.

Some people find social situations incredibly stressful and whenever they have to meet other people or go into an uncomfortable situation, they can start sweating excessively. This again is not hyperhidrosis but is excessive sweating due to anxiety. This is best treated by cognitive behavioural therapy, hypnotherapy or counselling and not medical treatments.
