At first thought, if sweating profusely, you'll want to make sure you replenish your electrolytes including sodium, potassium, magnesium, chloride, phosphorus, and calcium. As far as foods and tips that help sweating, here are some general recommendations: - Avoid: caffeine, spicy foods, garlic, onion, and actually alcohol too (Alcohol dehydrates your body at first. That is why you find yourself going to the bathroom so much when you drink. Your body is flushing out all of its fluids. However, this is only the first stage. After that, your body temperature begins to climb causing the acceleration of fluids to be flushed from your sweat pores as well. ) - Put on deodorant at night (Mitchum is a good one to try; or ask your Dermatologist for a clinical strength option) - Eat more of: sage tea, water, fruits, olive oil and other health oils, whole grains, and calcium-rich veggies (think greens and beans)!
