Tinea versicolor, a kind of fungal infection, is also one of the common fungal skin conditions that normally affect athletes. Excessive sweating gives a conducive environment for fungus to grow. 

This yeast infection can bring white patches on skin on the upper body, and self-esteem may be badly affected. It is more prevalent in tropical states than others. Management involves proper hygiene, antifungal treatments, and moisture-wicking clothes. Most cases respond to over-the-counter remedies while the stubborn ones may require prescription medication. It is not dangerous, though it may be chronic.
