If you want to have dry underarms then you must learn to stay calm. When people are trying to cure excessive sweating, or at least cope with the condition they’re told they have to learn to cope with their stresses and learn to relax themselves quickly. Nerves cause our sweat glands to open larger then usual, so for someone who already sweats a lot this can be a killer, causing them to sweat even more. In contrast if they’re able to calm themselves when these situations strike they’re better prepared to manage the condition, and stop any additional sweating before it ever starts.
