Raising the body's level of serotonin, a mood elevating chemical within the brain that creates a feeling of well being and relaxation. Offsetting excess levels of adrenaline generated by pressure and stress, magnesium ions relax and reduce irritability by lowering the effects of adrenaline. Pour 150-200g of the salts under running water immediately before getting into your warm bath. Soak for at least 20 minutes before using any other soap products.
