If you forget to inform you therapist about your health conditions you could aggravate your condition and end up having a poor experience. By informing your therapist of any allergies and ailments beforehand, this influences the spa treatment of choice and ensures that your experience will meet your expectation and be beneficial.  Always inform the spa of special needs you might need to be addressed, such as pregnancy, heart conditions or food requests, such a diabetic diet to ensure a perfect experience.
