All your thoughts, mental and emotional states are related to a specific physiological reaction of your body, i.e. the frequency range of waves that appear in your brain. Throughout the day, when you work, feel happy or stressed, and when you fall asleep, your brain jumps to different wave frequencies. This means that its electrical activity changes.
In this article, you will learn:
- What brain waves are.
- What the types of brain waves are: delta, theta, alpha, beta, gamma.
- How they affect your functioning.
Your brain’s electrical activity is the result of the communication between your brain cells – neurons. To do this, they use chemicals called neurotransmitters (such as serotonin and dopamine). This communication occurs at the interface between nerve cells at places called synapses. It goes on without interruption, even while you are sleeping. It only stops when you die.
This activity can be monitored with a device called an electroencephalographer (EEG), which records it as line waves. Thanks to this device, it is possible to effectively diagnose brain damage and dysfunctions, as well as determine the mental state of a person.
What are Brain Waves?
Brain waves are an exact reflection of what is happening in the brain, what is its emotional and mental state, and what are its limitations or possibilities in the implementation of an action or task.
The waves that the brain produces have different frequency ranges. Frequency is the number of vibrations that occur per second. It is measured in hertz (Hz). Some are slower and some are faster.
Your level of functioning and the states of consciousness associated with it change depending on your activity. This is because the work of your brain changes depending on your state of consciousness. Each of these conditions has a different frequency of brain waves. The frequency of your brain waves depends on what you are doing and feeling. When you feel tired, slower, dreamy, and slower, your brain works at lower frequencies. And when you feel overly alert, hyper-alert, and feel wired, your brain is working at higher frequencies.
We distinguish 5 types of brain waves:
Delta (1-4 Hz) SLEEP STATE, UNCONSCIOUSNESS
They are slow waves. They are accompanied by a state of rest and regeneration during deep sleep. As your brain works on these waves, your growth hormone is released and your cortisol levels drop. It is thanks to them that your body regenerates. These waves dominate in infants up to about 6 months of age. They also happen in a state of severe depression and in people with mental disorders.
It is a state of unconsciousness, astral travels, dreams, access to collective layers of the unconscious.
Theta (4-8 Hz) SUBCONSCIOUSNESS
The first sleep state. These are the waves that accompany the states of meditation, hypnosis, and trance. They are active during most sleep phases. During their activity, logical relationships and the ability to focus attention disappear. It is also a state where creativity is awakened and learning opportunities are increased. These waves dominate in children from about 6 months to 6-7 years of age. As you remember, the entire process of imprinting, i.e. programming your subconscious, is taking place at the same time. Thanks to these waves, you have access to all your brain’s memory. They stimulate your intuition and relieve stress. In this state, you feel less pain.
It is a state of shamanic trances, spiritual connection, light sleep.
Apparently, Thomas Edison used theta waves to write down his ideas. He fell asleep holding a metal ball in his hand over a metal plate. As it fell, it woke him up just as his brain was going into theta waves.
Theta waves are important waves because, in addition to helping you achieve the ideal mental and physiological state that is necessary for your body to heal itself, they also allow you to access the wisdom of your unconscious mind, which is not available in states of greater alertness.
Thus, by entering the state of functioning of the brain at theta frequency, it is able to reprogram its subconsciousness. You can change your beliefs, thinking patterns, and emotional reactions. These waves also help you learn new things and improve your long-term memory. These waves are also associated with psychic abilities.
Alpha (8-12 Hz). THE GATE TO THE SUBCONSCIOUSNESS
These waves are associated with a state of wakefulness accompanied by a state of deep relaxation. In 90% of people, they appear when you close your eyes. It is a state of rest, peace of mind, creativity, and tranquility. They reduce stress. You use them when you are daydreaming or fantasizing. These waves are responsible for dreams and creative plans. Support visualizations. In this state, you are still but not sleepy. These waves make you less depressed, friendlier, and brilliant. These waves disappear during both physical and mental effort.
Mystical state before and after sleep. Intuition.
If you have a problem with this frequency you have problems with memory. This frequency is used by Reiki healers.
Beta (12-32 Hz) AWARENESS
These are the waves that accompany you in your daily activities. You live the greater part of your life in these waves. That’s when you are focused and concentrated on receiving stimuli and experiencing emotions. And also when you think logically and communicate with your surroundings. This is when your senses are most productive.
However, staying in beta waves for too long causes stress, and chronic stress harms your well-being and health. You can stimulate these waves with coffee or energy drinks.
They enable you to function in physical reality.
Gamma (above 40 Hz) SUPERCONSCIOUSNESS, TRANSCENDENCE
These waves are involved in integrative and associative processes when processing complex information. Their appearance means high mental activity, including perception and awareness. These are the least-understood waves by scientists. They also occur during extreme emotions and experiences, as well as during REM sleep, when we experience dreams. Gamma waves are quite rare in common people, but they are found in Tibetan monks or mystics.
These waves are responsible for the state of self-awareness, insight, and the last level of awareness.
Can Brain Waves Be Controlled?
At the beginning of the 20th century, it was discovered that brain waves can be influenced by using various stimuli, e.g. visual and auditory stimuli through appropriate music or flashing light with the appropriate frequency. So it turned out that in this way we can shape our own reality.
Your daily experiences of the world and the functioning of your brain waves are inseparable. So when your brain waves are working out of balance, health, emotional and mental problems start to emerge. Over-agitation is associated with anxiety disorders, sleep problems, nightmares, hyperactivity, impulsive behavior, anger, aggression, depression, and chronic pain.
Brain rhythm instability is associated with tics, obsessive-compulsive disorder, panic attacks, migraines, dizziness, anorexia, bulimia, and diabetes.
You can influence how your brain waves work in many different ways and with many different tools. Through meditation, visualization, hypnosis, biofeedback, mindfulness, through the Theta Healing method, Silva method or the Ilchi Lee method of Brainwave Vibration. You can choose the method that suits you best.
It’s crucial to understand that managing your own brainwaves in a healthy way has an impact on your health and well-being. You spend hours working on the condition and shape of your body, but do you spend even a moment on your own brain waves? Maybe it’s time to change it?
