Hello sir.. The place where you are residing I actually a humid place...so normally you tend to sweat out more as compared to other places..it's because you stay in a coastal area...apart from this..your body weight might also be a reason why you sweat a lot...try to reduce your weight if its a reason...the other reason may be thyroid issues..we just need to find out what the cause is in you...you can consult a physician ..thank you
