Final answer:
The incorrect statement about massage therapy is that it is unregulated in most states; in fact, many states require licensure. Massage therapy also stimulates endorphin release and can relieve sports injury pain, and it has ancient roots in practices referenced by Hippocrates. So the correct answer is Option C.
Step-by-step explanation:
The statement that 'It is unregulated in most states' is not true about massage therapy. Massage therapy is a regulated practice in many states, requiring practitioners to have a license or certification to practice. Massage can help stimulate the release of endorphins, which are the body's natural painkillers and mood elevators. It is also effective in relieving pain from sports injuries, and indeed, it is an ancient art referenced by historical figures such as Hippocrates. Since massage therapy is regulated, practitioners must adhere to strict hygiene and safety standards, which reduces the risk of exposure to pathogens. In contrast, acupuncture, another form of alternative medicine, may pose a risk of pathogen exposure if needles are not properly sterilized.
