Brainwaves described

It is very important to understand how your brain works and how it contributes to your state of mind. Most of us are used to focus on our emotions trying to become happier or a more spiritual being. What most of you don’t know is that your brain waves and your subcionscious mind play a big part in this pursuit of happiness.
Let’s take a look at your brain wave frequencies and how they affect the state of mind. Each frequency is measured in cycles per second (Hz) and has its own set of characteristics. Each of these waves represent a specific level of brain activity and a unique state of consciousness.

Let’s begin with Beta. Its range is 14-40Hz and is the wave of your wide awake state.
Beta brain waves are associated with normal waking consciousness and an increased state of alert, logic and critical reasoning.
Beta brain waves are essential for your effective functioning throughout the day, but they can also translate into a stressful, restless and anxious mind. 
Imagine Beta as that annoying little inner critic that gets louder and louder. Once it gets lounder, it means that your brain waves are high into above mentioned range and that stress is just around the corner or it has already arrived.
The majority of adults operate at Beta, this is why stress is the most common problem these days.

10 interesting facts about our brain

Our brain is made up of about 75% water.

While awake, our brain generates between 10 and 23 watts of power, enough energy to power a small light bulb.

There are no pain receptors in the brain, so the brain can feel no pain.

There are over 150,000 km of blood vessels in the brain.

If our brain loses blood for 8 to 10 seconds, we will lose consciousness.

Boredom is brought on by a lack of change of stimulation, is largely a function of perception, and is connected to the innate curiosity found in humans.

Our brain consists of about 100 billion neurons.

The human brain is the fattest organ in the body and may consists of at least 60% fat.

Women tend to take longer to make a decision, but are more likely to stick with the decision, compared to men, who are more likely to change their mind after making a decision.

Our skin weighs twice as much as our brain.

About brainwaves

Our brain is made of billions of cells called neurons. To communicate with each other, neurons use electricity. The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using sensitive medical equipment, measuring levels of electricity over areas of the scalp.
The combination of electrical activity of the brain is commonly called a 'Brainwave pattern', because of its cyclic, wave-like nature.
Our mind regulated its activities by means of electric waves which are registered in the brain, emiting tiny electrochemical impulses of varied frequencies, which can be registered by an electroencephalogram (EEG).
With the discovery of brain waves, came the discovery that electrical activity in the brain will change depending on what the person is doing. For instance, the brainwaves of a sleeping person are vastly different than the ones of someone wide awake. Over the years, more sensitive equipment has brought us closer to figuring out exactly what brainwaves represent and with that, what they mean about a person's health and state of mind.
The known brainwaves and their associated mental states are:
- Beta emited when we are consciously alert, or we feel agitated, tense, afraid.
- Alpha when we are in a state of physical and mental relaxation, but aware of what is happening around us.
- Theta which is a state of somnolence with reduced consciusness.
- Delta when there is unconsciousness, deep sleep or catalepsy.
