What Are Delta Brainwaves?
Delta waves represent the brain’s slowest frequency range, and cycle at a rate of 1-4 times per second (1 Hz – 4 Hz). Delta waves dominate when you are in a deep sleep, and are the dominant brainwave pattern among infants. High amplitude Delta brainwaves in adults frequently accompany brain injury or brain disorders. They may also be observed in the EEG’s of children with ADHD, along with Theta waves. Loss of bodily awareness is accompanied by Delta waves. For example, Delta brainwaves would be observed in the EEG of an unconscious person. Arrhythmic Delta brainwaves have been observed in college students during problem-solving tasks.
Increasing Delta brainwaves increases your natural ability to release anti-aging hormones, heal your mind, repair your muscles, and access the deepest state of relaxation. Delta waves have been known to reduce levels of cortisol (the hormone released when you are under stress) in the body. Cortisol kills brain cells and has been linked to quicker aging.
Increased Delta brainwave activity has also been shown to increase feelings of empathy – the ability to stand in another’s shoes and understand how they feel. Increased Delta brainwaves allow you to connect with the deeper parts of your unconscious mind, potentially releasing buried memories. Delta brainwave programs are designed to assist you in falling asleep, and reaching deeper levels of meditation and higher levels of spirituality.
