Excessive sweating

Excessive sweating

Excessive sweating happens when the sweat glands (eccrine glands in particular) overreact to stimuli and are generally overactive, producing more sweat than what’s necessary. This can have a huge impact on your daily activities and life over all. What is excessive sweating or hyperhidrosis? Hyperhidrosis is characterised by excessive, non-functional sweating. In case you believe that you suffer from Hyperhidrosis you should seek medical advice, as it can be caused by a medical condition or be a side effect of medication. 


Cause of excessive sweating

Why do I sweat so much? Sweat is essential to human survival and serves as the body’s coolant, protecting it from overheating. Sweat often appears when you are physically active or are located in a hot environment, but it can also be triggered when you are emotionally affected such as when you are feeling stressed, anxious or experiencing fear. Sweating can also be a response to hormonal changes such as puberty, pregnancy and menopause. That’s all normal but your experience can still be uncomfortable. Excessive sweating can also be a side effect of different medications or diseases. If you suspect the reason for your excessive sweating is caused by either or, you should seek medical advice. 

Why do I sweat so easily?

People who are fit, will sweat more and faster than people who are not. That’s simply because they have trained their body to sweat whenever they are physically exerting. Meaning they start sweating when their body registers overheating.

  • Climate (heat and humidity)

  • Embarrassment
  • Stress
  • Excitement
  • Nervousness
  • Fear
  • Anxiety
  • Anger


  • Disease-included sweating
