If You sweat a lot so use a lot of deodorant during workouts such as the hardcore kick boxing workouts taught by Stephanie, Personal Trainer in Houston, You may wish to switch to non aluminum deodorants. Recently, the FDA ruled that deodorants must have a warning label that they can be hazardous. This is because most deodorants contain aluminum which increases the risk of Alzheimer's and Parkinson's disease. The new rule affects ninety percent of the deodorants on the market. For natural deodorants without aluminum, try Jason's natural cosmetics Tea Tree Deodorant stick (helps with odor), or Kiss My Face Liquid Rock deodorant (helps with wetness).
