See my Meditation Collection for 10, 15 or 20 minute videos like this. Also available in Alpha, Beta, Gamma, Theta and Delta Waves (see below). The Transcendental Meditation (TM) tradition often recommends 20 minutes, twice daily. Interventions based on the Relaxation Response (Benson, 1975) also often recommend 20-minute. 1. Alpha Waves Alpha waves are the most common brain waves that occur at the beginning of meditation as you try to go into a deeper state of mind. They are electromagnetic oscillations with a frequency range of 8-12 Hz. Function: Alpha waves calm the nervous system. They lower blood pressure and heart rate. The waves lower the production of stress hormones and promote relaxation. 2. Beta Waves Beta waves occur with a frequency range of 12-30 Hz. They become active when the brain is working on goal-oriented tasks, such as planning an event or pondering over an issue. Function: Beta waves create awareness and improve concentration. They increase logical thinking and develop your conversational abilities. 3. Theta Waves Theta waves are often associated with the ‘third eye’ as they help us tap into our wisdom, according to spiritual teachings. These become predominant when we do any task that is automatic like driving, washing clothes, shampooing hair, folding clothes, etc. They are also present in daydreaming and paranormal phenomenai . Function: Theta waves provide a positive mental state and encourage creativity. They improve your problem-solving skills and increase your memory. The waves improve your focus and keep you calm and balanced. 4. Gamma Waves Gamma waves are associated with intense focus. Function: Gamma waves decrease anxiety and fear and increase positive emotions. They reduce depressive feelings and symptoms. 5. Delta Waves Delta waves are high amplitude brain waves with a frequency of 0-4 Hz. These brainwaves are associated with the deepest stages of sleep.
