THE 5 MAIN TYPES OF BRAINWAVE FREQUENCIES

Different patterns of brainwaves can be recognized by their amplitudes and frequencies. Brainwaves can then be categorized based on their level of activity or frequency. It’s important to remember, though, that brainwaves are not the source or the cause of brain states, or of our experiences of our own minds – they’re just some of the detectable reflections of the complex processes in the brain that produce our experience of being, thinking, and perceiving.
I. GAMMA BRAINWAVES
II. BETA BRAINWAVES
III. ALPHA BRAINWAVES
IV. THETA BRAINWAVES
When we’re doing a task that is so automatic that the mind can disengage from it e.g. brushing teeth, showering. Research has also shown a positive association of theta waves with memory, creativity and psychological well-being. [2],[3],[4],[5]    
V. DELTA BRAINWAVES

BENEFITS OF INCREASING DELTA BRAINWAVES 

State of empathy - Delta brainwaves can provide you with the ability to read other peoples emotions and determine their feelings at unconscious levels. In healthy amounts, delta brainwaves cause a person to have an advanced state of empathy, understanding, and compassion for others. If you are always able to relate to others and can "read other people's minds,” you probably have more delta than the average person. If you find yourself getting into trouble for not being considerate enough or for "stepping on other people's toes,” you may have less overall delta brainwave activity. [6]
Advanced healing of body and mind - The delta brainwave rhythm is known to completely rejuvenate, replenish, and heal the entire body and brain. The delta brainwave revives the body after a hard day by regenerating necessary chemicals while a person is asleep. Due to the deepest levels of relaxation that the delta brainwave provides, the body and mind are easily able to restore themselves after minor stress, a rigorous workout, or after boosting your brain power. [6]
Human Growth Hormone (H.G.H.) Release - The delta brainwave is associated with the stimulation of the pituitary gland, which in-turn, is able to release humangrowth-hormone — commonly referred to as H.G.H. It doesn't release enough for you to skyrocket in height and weight. The delta brainwave will not provide adults with a second version of puberty. With that said, there is evidence that it does release slight amounts of H.G.H. in certain individuals. If you are looking to increase your H.G.H., you should definitely consider using delta brainwave entrainment and evaluate how it works out for you! [6]

THE BENEFITS OF INCREASING THETA BRAINWAVES 

 Sleep and Dreaming - Theta brain waves are slow and relaxing brainwaves that are usually associated with us when we sleep and are dreaming. Located in the right hemisphere of the brain, they usually arise when we are dreaming, sleepy, emotional, relaxed or daydreaming. Although we all possess theta brain waves, they are most commonly accessible for people that struggle with ADD, or those that dream in a very relaxed state. Artists are known to have frequent theta brain waves as well as any other highly creative individual. Whenever we are really and truly relaxed, dreaming in a deep slumber or creatively thinking, we may be utilizing theta brain waves. [6]
Musicians, sculptors and artists - Since theta brain waves operate at a much slower rate, there are many benefits to our emotional state of mind. It’s unlikely that many adults will experience theta brain waves during their waking hours, but many children two and under experience it on an ongoing basis. Children have the ability to feel relaxed at all times (except when they cry) but as adults, our brain is usually experiencing alpha or beta brain waves. When we sleep and are totally relaxed, we can easily experience theta brain waves. Musicians, sculptors and artists of many genres are able to experience more theta brain waves than other individuals. This is because they tap into theta brain waves as a way to become creative when there ‘artistic juices’ have run out . [6]
