What are Beta Brainwaves?
Beta waves are naturally generated by the brain when we are in an awake, alert state of consciousness, and oscillate between 13 to 40 times per second. A highly excited or anxious brain will generate very high levels of Beta waves (25 – 40 Hz). A calm, but highly focused brain generates levels of Beta waves in the range of 14 to 18 Hz.
Beta waves are most present when you are wide awake and alert, as your neurons are firing abundantly, and in rapid succession. Your mind is sharp and focused. You are able to quickly and easily make connections, and you’re primed to do work that requires your full attention.
Increased Beta brainwaves can help you prepare for an exam, give a presentation, or analyze and organize information – in other words, help you to perform activities where mental alertness and high levels of concentration are critical to your success.
Extremely high frequencies of Beta brainwaves are associated with fear, anxiety, excessive thinking, rapid thinking, OCD (Obsessive-Compulsive Disorder), addiction, and states of peak performance.
Too much Beta brain wave activity in the right hemisphere of your brain is linked to anxiety, tension, and worry. If you are highly alert, nervous, or a hypochondriac – you have likely experienced more than the average share of high Beta brain waves. Stressful events and tension are known to increase Beta brainwave activity in the brain.
Beta waves observed in the left hemisphere of your brain are considered healthy, and increased Beta brainwaves may be of great benefit to those suffering from depression and lack of energy. Lower levels of Beta brainwaves (14 to 18 Hz) are optimal for focusing, analyzing, performing calculations, and thinking about your external environment.
