Delta brain waves are generated mainly in the right hemisphere of the brain, like alpha and theta waves. The range of delta brain waves is associated with empathy, unconsciousness and a reduced sense of awareness. We fall into a deep sleep when delta waves begin to dominate over the other waves in our brain. Healthy delta wave activity in the brain causes a developed state of empathy, understanding and compassion for others. Delta wave activity reduces the level of cortisol, which is the hormone that accelerates the aging process.
The emanation rate of delta waves: 0.5-4 Hz.
Our brain emits theta waves when a person is almost asleep or just woke up. They are important waves as they define the bridge between consciousness and subconsciousness. In the theta state we can influence the crucial part of subconsciousness that is unavailable in the usual wakeful mind. When we are at the theta state we gain increased capabilities of deep healing, development and growth.
At the same time, it could be dangerous to activate the theta state too much for some people with already a high level of these waves. It could cause sleepiness, distraction and suggestibility.
The emanation rate of theta waves: 4-8 Hz.
Alpha brain waves occur naturally in the period of slight relaxation, or when the eyes are closed, but the person is actually not asleep.
Children are in a state of activity of alpha waves most of the time, more so than adults. Alpha waves reduce stress and anxiety and alike theta waves contribute to enhanced learning and the development of intuition and creativity.
However, remember that if alpha waves are produced in sufficient quantities, their excessive activation may cause a loss of concentration and depression (when exhaustion, laziness and sleepiness cause depression in your case), as well as heightened suggestibility.
The emanation rate of alpha waves: 8-12 Hz.
Beta brain waves usually occur in the waking state and are dominating waves for a healthy adult. When a person is talking, the activity of beta waves naturally accelerates and becomes predominant. However, beta waves also determine the active, loaded, anxious thinking or active concentration.
Therefore, if you are an energetic person or you are in a state of stress, you should avoid the stimulation of beta waves. In addition, an increase of beta activity before falling asleep contributes to hyposomnia.
The emanation rate of beta waves: 12-40 Hz.
Gamma brain waves (subgroup of beta waves) are the fastest waves that reflect the peak activity of the consciousness of a human being.
The emanation rate of gamma waves: 35-45 Hz.
Modern methods of computer analysis of brain electrical activity revealed that in the waking state all waves are present in the brain. The efficiency of the brain is connected to the synchronization of oscillations observed in all ranges of waves in symmetric areas of both hemispheres of the brain. Perhaps the most important aspect linking brain waves with a person’s health is the ability to modify these waves according to the requirements of the situation.
