<span>When alpha waves are dominant in your brain (8-12 Hz), you will feel very relaxed. This happens when you are waking up in the morning.</span>
Alpha waves can be created thru aerobic exercise. Progressive relaxation also increases alpha waves. Biofeedback<span> is a technique used to create alpha brain waves also, in order to prevent or treat conditions like headaches, chronic pain, and high blood pressure. </span>
