Ask any massage therapist, acupressure professional, or other alternative health therapist and they will tell you that what they do can be considered not only therapeutic, but also as preventative maintenance for your body. Alternative health treatments are designed to improve your circulation, rid your body of toxins, and grant you relaxation so your immune system can function properly. Not everyone has the time, money, or inclination to make recurring appointments with massage therapists and other alternative medicine professionals, but luckily there are plenty of books that can teach you enough about these forms of natural health treatments to where you and your partner can learn how to do basic moves on each other.
For example, you can buy a basic reflexology book which will categorize moves based on the ailment; a stomach ache is treated with specific rubbing on a certain body part and the book explains it thoroughly, just like headaches, muscle pain, or any other common discomfort. Of course, not every alternative treatment will have a reliable do-it-yourself book. You probably wouldn't want to attempt acupuncture on your own, even with a trusted partner. Always consult your medical professional before attempting any do-it-yourself herbal remedies.
