How Light Affects Brainwaves

No doubt about it the discovery and subsequent study of brainwaves has had  tremendous impact in our understanding the way our brain functions. Brainwaves result from the brains electrical activity.

As odd as it sounds the brain does generate a certain level of electricity, measurement, and study of this is what forms the basis of brainwave technologies.

The frequency of brainwave activity is measured in hertz, forms the basis of the categorization of brainwaves into Beta waves, Alpha waves, Theta waves, and Delta waves. The instrument used to measure this is the EEG electroencephalograph.

Research has proven that light has an effect on brain waves. Years ago, researchers discovered that strobing- which is also known as repetitive light stimulation had an effect on brainwaves, it was discovered that it made them to follow and pulse at the same speed or frequency.

This is known as the frequency-following effect.  Brainwave activity has been observed to have a tendency to always kind of mirror light, especially flickering light.

This has been strongly observed in the  Alpha and Beta wave states. If you don’t believe this, try and focus on watching a flickering fire, you’ll observe that there is a very strong tendency for you to fall into some kind of relaxed or even dreamy state while looking at or gazing at the flickering fire.

This light stimulation effect is being seriously employed in brainwave technologies these days to help achieve different states of awareness from relaxation to meditation to improvement of perception.

Traffic lights also have been observed to have an effect on brain waves. For example it has been observed that those who are farther away from the traffic light especially at the red stoplight in traffic, have reactions that are better than the reactions  of those near the light by a very high margin.

This is practically observed in the fact that if you are the one at the back of the cue, your reaction time to the change of light from red to green will be faster than that of those who are closer to the light such that, you may have started moving your car into gear only to discover that those ahead of you have not yet reacted to the traffic light change.

If you’ve found yourself in such positions before you now know why the cars in front of the queue seem to be taking forever to move.

Today, the effect of light on brainwaves is being employed in brainwave technologies. Manufacturers of mind machines use this effect to develop machines that produce the strobe effect and help to draw the mind into different states of awareness hence enhancing relaxation and productivity.

It has been discovered that when the light effect is used together with sound effects, wonderful results occur.

Brainwave studies and technologies now have been found to be very useful in dealing with health issues as they help you relax and control the frequencies of your brainwave activity. The Internet offers you easy access to these advances. Check it out, you’ll be amazed at the results.
