Biofeedback

Biofeedback is an alternative medicine with the intent to give the patient greater awareness of their physiological functions, which will supposedly help the patient control these processes. With this premise, it is un suprising that some claims are utter bullshit.

The promising
There is some evidence that shows that biofeedback could potentially help with stress.

The woo
Some take biofeedback one step further and claim unsubstantiated and embarassing crap that would make anyone with any dignity ashamed, and that's why many of these claims are made by quacks, cranks, and new agers. These include claims of more desirable brainwaves, being able to reach spiritual or higher consciousness, and stuff that is just plain impossible for the human body to do.
