Itchy with sweat. How to stop ?

I sweat, there is severe itching. 3 years.if you are kindly requested to tell me the treatment.

Stay very clean. Do not drink caffeine. Take cool showers or baths. Put antipersperant on all places you sweat most, folds of your skin, leg-butt creases, under your breasts, across forhead. The itching is probably coming from drying salt in your sweat, or yeast growth, clean areas everyday. Should help, good luck.
