At the slowest delta level, sleep is deep and dreamless.ĭuring our waking and sleeping hours, the brain moves through all four of these stages. During delta, brainwaves range from 1.5 to 4 cycles per second. Deep meditation and prayer are practiced in the theta state.ĭelta is the slowest of the four states where sleep occurs. It is often in this state that answers to problems seem to appear. In this state of mind, memories, thoughts and facts that eluded a person in a wakeful state can be recalled. It is the state between wakefulness and sleep.

During theta, brainwaves range from 5 to 8 cycles per second. Theta is an even slower state perfect for daydreaming and intuitive thinking. Meditation is often practiced in the alpha state. In the alpha state, an individual is fully aware of his/her surroundings but in a much more relaxed state of mind than beta. During alpha, brainwaves range from 9 to 14 cycles per second. During beta our minds are the most alert.Īlpha is a slower state more indicative of relaxing and reflecting. This is our normal state of mind when working, going to school and shopping. In beta, an individual thinks and listens, can solve analytical problems, make decisions, and intake and process information. During beta, brainwaves range from 14 to 40 cycles per second. From highest to lowest frequency, these brainwaves are called beta, alpha, theta and delta.īeta is the waking, thinking state. Electrodes placed on the scalp measure the frequency of these brainwaves.

The frequency of these brainwaves can be measured using an electroencephalograph (EEG). By learning to control these states, we can improve our health and well-being.īrainwaves are the electrical movements in the brain. Meditation is the process of slowing our waking beta brainwaves to the slower states of alpha and theta. By raising or slowing our brainwaves, we can altar how we think, feel and act. Control your brainwaves and you control your state of mind.
