Whether it's deep breathing or visualization, implement a strategy for coping with stress. Cognitive behavioral therapy may actually help you react to triggers in a more calm fashion where your body won't react the same way. Sometimes diet can trigger increased perspiration. Keep a food log. Also record when you find you're sweating the most. Look at the correlation to see if certain foods are setting you off. Many times caffeine and spicy foods can exacerbate the problem. If you can pinpoint the trigger, eliminate it from your diet. If the problem persists, consult your dermatologist about Botox injections, which paralyze the nerves in the sweat glands.
