Although Gamma brainwaves are faster than Beta brainwaves, the latter are considered the fastest brainwave frequency by many.
This is probably because Gamma waves were the latest to be discovered, and there are still some who don't mention them at all.
Having said that, Beta brainwaves range in frequency from 12 Hz to 38 Hz and though they are generally produced by the brain's left hemisphere, they can also be produced in synchrony by both hemispheres.
Beta brainwaves are prevalent among adults, specially when they are wide awake and are associated with lucid thinking, social skills, focused concentration and peak performance.
In children, Alpha is the prevalent brainwave pattern, but as people grow older, Beta brainwaves increase to the point that they usually become the predominant pattern.
It is a fact of life, part of the natural evolution process that human beings experience.
No single brainwave pattern is better than the others.
Each type of brainwave serves a purpose and the lack of either of them might result in imbalances that should be looked into.
There are many benefits related with a healthy Beta brainwave activity, which we will point out before long.
Just as there are benefits, there are also drawbacks like stress, anxiety, insomnia and tension.
These usually appear when Beta activity is higher than usual.
Following are the benefits of having healthy Beta brainwave levels.

1. Quick Thinking.
   
Beta brainwaves help you process information at a quick pace, giving you the ability to think fast and speed up your ideas.

2. Social Skills.
   
Have you ever felt like talking non stop? Beta brainwaves might have had something to do with it.
When your beta activity increases, your conversational skills get a boost.
It could definitely help next time you want to socialize.

3. Focused Attention.
   
Beta activity helps you direct your attention to your primary objective and cast aside all other matters that may distract you.
When you read a book, for example, you are in Beta.

4. Higher IQ.
   
Recent studies have shown that people with dominant Beta activity usually score higher in IQ tests.
This comes as no surprise, since people who read and solve math problems, have a better chance of building a smart brain.

5. Higher Energy.
   
Beta brainwaves raise your stamina.
So if you normally feel worn out and wish you were more energetic, chances are you might have low Beta levels.

6. Peak Performance.
   
This is a common benefit to other brainwave patterns too.
With Beta, though, it's easy to see that if you can focus your attention for longer periods of time and your energy level is higher, then your performance will likely improve.

7. Positive Thinking.
   
Since the left hemisphere is associated with positive thoughts and beta brainwaves are primarily produced there, people with healthy Beta activity tend to have more positive thoughts.

8. Logical Thinking.
   
This comes naturally when you can focus your attention at solving a problem or learning a subject, because your brain is able to dig deeper into the subject and find a rational course of action.

Modern science has developed tools and techniques that can help you increase your beta brainwaves so that you can experience all their benefits.
Brainwave Entrainment is one of such techniques that utilizes sound stimuli to entrain your brain in as little as six months.
Eventually, you learn how to master your brain and access brainwave patterns at will.
This is in contrast to traditional methods like meditation or yoga, which usually take years to dominate.
