Beta Alpha Theta Delta Brainwaves
The fastest computer you can imagine is slow compared to your brain.
There are five categories of brain waves, ranging from the least activity to the most. You’ve probably heard of Beta and Alpha. The brain wave categories include Delta, Theta, Alpha, Beta and Gamma. Some researchers lump Gamma and Beta into the same category, calling them both Beta waves.
Delta Brain waves: Up to 4 cycles per second
Delta – up to 4 pulses per second (240 per minute) is the slowest brainwave. Delta brainwaves have the greatest amplitude and slowest frequency, and may occur when you’re in a deep, dreamless sleep. Most adults are so perpetually wound up that they can’t even achieve Delta in their sleep, but newborns and children sleep in Delta very frequently. That’s what it means when people talk about sleeping like a baby; babies sleep deeper sleep than most adults do.
Theta Brain waves: 4-8 cycles per second
Theta waves are associated with creativity, dreams and Extra-sensory perception. When you’re in dreaming sleep, during the rapid eye movement state of sleep (REM) that’s the Theta state. Theta is when your conscious mind is disengaged, and it’s the goal of deep meditation and relaxation. We achieve Theta any time tasks become so automatic that you can mentally disengage from them. The ideas that often bubble up during the theta state are free flow and occur without mental censorship. Theta is often the state of mind we’re in when showering or taking a bath. (Eureka!) Many adults only attain theta waves in their sleep, and can not seem to attain Theta when they are awake, except perhaps in the shower.
Alpha Brain waves: 8-12 cycles per second
Alpha waves were first discovered in 1908 by an Austrian Psychiatrist named Hans Berger. Alpha is the state of mind when you are awake, but very relaxed, like when you’re daydreaming. It’s an effortless state of consciousness. Most people go into Alpha state when they are watching television or a movie. Children tend to play in Alpha. Low Alpha – just before crossing into Theta – is that state of being “not quite all there” that you experience just before you fall asleep or when you’re just waking up.
Beta Brain waves: Over 12 cycles per second
Beta waves are the awake state, and indicate a strongly engaged mind. Engaged in what is the question. Beta waves can mean a calm conversation where your brainwaves are 14 cycles per second… but beta waves can also mean high beta or gamma waves that result in stress, anxiety, fight or flight reactions or a full blown panic attack.
The Beta state is also where we focus, learn, create, study, memorize, write and change our lives. So, let’s look at beta brainwave patterns a little deeper.
