1. Wash thoroughly every day Although sweat itself has a neutral odour, we often associate it with an unpleasant smell. The smell is due to the fact that the bacteria found naturally on the skin break down the substances in sweat. It is this process that emits the unpleasant odour. So, if you feel you might smell, it is important that you wash the bacteria away.
2. Use antiperspirant If your regular deodorant is not enough, try an antiperspirant. Antiperspirants prevent sweat (sweat odour, moisture and sweat stains) by reducing sweat production in the sweat glands. Depending on the efficiency of the antiperspirant, the effect lasts from a few hours to several days. If you choose an antiperspirant that is fragrance free, you can easily use your regular perfume and deodorant with it. Use it in the evening on clean, dry, undamaged skin.

3. The appropriate clothes If you sweat a lot, choose clothes made from natural materials such as cotton, which are better at absorbing sweat. Otherwise, it is also a good idea to avoid blouses in bright colours, where you can clearly see if you are sweating under your arms.
