This is what those brainwave synchronization companies selling CDs don't tell you about brainwave synchronization.  Brainwave synchronization does more harm than good.  Don't listen to brainwave synchronization if you know what is good for you!

Typical Side Effects of Brainwave Synchronization

Headache

Days to weeks after listening to Brainwave Synchronization, some people report depression.

Other Side Effects of Brainwave Synchronization

Delta (3Hz-6Hz)

Very Sleepy, difficulty waking up.  Also difficulty concentrating. 

Theta (6Hz-8Hz)

Dreamlike state.  Difficulty concentrating.  Many people have reported seeing "Swirls" while listening to high intensity Theta waves. Shortened attention span. 

Alpha (8Hz-12Hz)

One to two weeks after listening to Alpha waves some people report seeing psychedelic colors for 30-45 minutes. Your vision should return to normal. If this happens, I suggest that you stop listening to brainwaves.

Some people report feeling exhausted and having abnormal fluctuations in their circadian rhythm (irregular sleeping patterns) one to two weeks after listening to Alpha waves. Your sleep patterns should return to normal after about two weeks of not listening to brainwaves.

Many people have reported having vivid dreams and nighmares after listening to Brainwave Synchronization.

Dilated pupils.

Some people may see spots (which are often purple) and have eye pain a few days to weeks after listening to Brainwave Synchronization.

A week or two after listening to Alpha brainwaves, sudden stabbing pains in the back of the head are common.  Following this comes difficulty spelling words, concentrating, and reading.

Paranoia, sensitivity to lights, and sensitivity to sounds are common a week or two after listening to Alpha.

Rapid heart beat.

Pounding heart beats.

Vivid Dreams (and nightmares)
