Here is a chart showing these four waves
Chart of Brain Wave qualities
Beta Brainwaves 14-40Hz — Awake Conscious & Reasoning
Beta brain waves are associated with normal waking stateand a good sense of alertness, logic and critical reasoning.
Beta brain waves are important for effective functioning throughout the day, they can lead to stress, anxiety and overthinking.
Alpha 7.5-14Hz — Deep Relaxation Brainwaves
Alpha brain waves are present in deep relaxation, lovely daydream or during light meditation.Typically when the eyes are closed,
It is an optimal time to program the mind for success, floow up with affirmations and creative visualization.
Alpha brain state allow acces to greater imagination, memory, learning and concentration.
Acces your subconscious mind, base of your conscious awareness.
Alphai state get you in touch with your intuition, it becomes clearer and more profound the closer you get to 7.5Hz frequency.
Theta 4-7.5Hz — Deeper Meditation, Approaching Sleep
Theta brain waves are present during deep meditation and light sleep, including the all-important REM dream state. It is the realm of your subconsciousness and only experienced momentarily as you drift off to sleep from Alpha and wake from deep sleep (from Delta).
It is said that a sense of deep spiritual connection and unity with the universe can be experienced at Theta.
Your mind’s most deep-seated programs are at Theta and it is where you experience vivid visualizations, great inspiration, profound creativity and exceptional insight. Unlike your other brain waves, the elusive voice of Theta is a silent voice.
It is at the Alpha-Theta border, from 7Hz to 8Hz, where the optimal range for visualization, mind programming and using the creative power of your mind begins. It’s the mental state which you consciously create your reality. At this frequency, you are conscious of your surroundings however your body is in deep relaxation.
Delta 0.5-4Hz — Deep Sleep and Restful Slumber
The Delta frequency is the slowest of the frequencies and is experienced in deep, dreamless sleep and in very deep, transcendental meditation where awareness is fully detached.
Delta is the realm of your unconscious mind, and the gateway to the universal mind and the collective unconscious, where information received is otherwise unavailable at the conscious level.
Among many things, deep sleep is important for the healing process — as it’s linked with deep healing and regeneration. Hence, not having enough deep sleep is detrimental to your health in more ways than one.
Gamma 40Hz) and Higher – Insight and Informatin Proccessing
This range is the most recently discovered and is the fastest frequency at above 40Hz. While little is known about this state of mind, initial research shows Gamma waves are associated with bursts of insight and high-level information processing.
