When you put one foot in front of the other to walk or when you pick up a pen to write, you are consciously in control of these things. You direct your body to make them happen.
However, there are things your body does that you don't directly control. Things such as your heart rate, skin temperature, and blood pressure. These are all maintained involuntarily without you even having to think about them. Changes in your heart rate or blood pressure when you are nervous or anxious, are reactions that happen automatically within your nervous system.
Biofeedback is a technique that can help you gain more control over these automatic functions. It can be used to help prevent or treat all sorts of conditions including migraines, anxiety, stress, chronic pain, incontinence, panic attacks, high blood pressure and many others. Biofeedback also promotes relaxation and can lower blood pressure and downregulate resting heart rate.
By harnessing the power of your mind to gain control over these bodily systems, you can alleviate a lot of health and well-being issues previously found difficult to treat.
