Some of us sweat more than others

Why do I sweat so much?

On average we sweat about one litre per day, but most of it evaporates so we don’t notice it. We can sweat up to 10 litres a day if we’re really hot or exercising hard.

Where do we sweat?

Most people are concerned about armpit sweat, but this accounts for only 1% of our body’s perspiration.

We sweat from two types of glands:

  • Eccrine glands: These appear all over the body and are mainly for cooling. They cause sweat on our face and head, and are responsible for sweaty hands and sweaty feet.
  • Apocrine glands: These larger glands appear mainly under the armpits and are mostly active when we’re exercising or experiencing strong emotions like stress.

Women have more eccrine sweat glands than men, but men’s eccrine glands are more active, so men actually sweat and have more hot flushes overall.

Sweating can also occur on areas of the body such as the back, groin, chest or even feet. Excessive sweating in these areas can be very uncomfortable. 


How much should I sweat?

Really, there are no guidelines that state what a “normal” amount of sweat is. Some people sweat more than others for a wide range of reasons.

Factors like hot flushes, eating spicy food, wearing clothes made out of synthetic materials, and carrying excess body weight can cause us to sweat more. In general, our bodies adapt to produce sweat when we really need it. 

Using an antiperspirant deodorant like Sure® Women Maximum Protection Confidence or Sure® Men Maximum Protection Clean Scent will help keep you feeling fresh no matter what.

That said, sweating too much can still be a problem. Roughly 1% of people who experience excessive sweating  have a medical condition known as hyperhidrosis.


What is Hyperhidrosis?

With hyperhidrosis, the system that controls when and how much you sweat is “revved up”. This causes sufferers to sweat more than usual and often at inappropriate times.

Hyperhidrosis can affect the whole of your body, or it may only occur in certain areas like your back, the palm of your hands or face and chest.
