A delta wave is a high amplitude brain wave with a frequency of oscillation between 0.5–4 hertz. Delta waves, like other brain waves, are recorded with an electroencephalogram (EEG) and are usually associated with the deep stage 3 of NREM sleep, also known as slow-wave sleep (SWS), and aid in characterizing the depth of sleep.<ref>[https://en.wikipedia.org/wiki/Delta_wave Delta Wave]</ref> | A delta wave is a high amplitude brain wave with a frequency of oscillation between 0.5–4 hertz.

These are the slowest recorded brain waves in human beings. They are found most often in infants as well as young children. As we age, we tend to produce less delta even during deep sleep. They are associated with the deepest levels of relaxation and restorative, healing sleep. They have also been found to be involved in unconscious bodily functions such as regulating heart beat and digestion. Adequate production of delta waves helps us feel completely rejuvenated after we wake up from a good night’s sleep. If there is abnormal delta activity, an individual may experience learning disabilities or have difficulties maintaining conscious awareness (such as in cases of brain injuries). | |||
* Frequency range: 0 Hz to 4 Hz (Slowest) | |||
* Too much: Brain injuries, learning problems, inability to think, severe ADHD | |||
* Too little: Inability to rejuvenate body, inability to revitalize the brain, poor sleep | |||
* Optimal: Immune system, natural healing, restorative / deep sleep | |||
* Increase delta waves: Depressants, sleep | |||
