The Different Types of Brainwaves
The brain is made up of electrical signals that cause thoughts, emotions and behaviors. These impulses create brain waves which can be measured using portable EEG devices and neurofeedback equipment.
Different brainwave patterns exist on a frequency spectrum, just like colors. These waves are generally measured in cycles per second (Hz) for accuracy.
Delta Waves (0.5-3.5 Hz): These slowest of all brainwaves are often associated with deep sleep and healing. Additionally, they help people focus and concentrate during meditation.
Theta Waves (3-8 Hz): These waves have numerous benefits, such as relieving anxiety and chronic pain. Furthermore, they help people relax and improve their sleep quality.
Alpha Waves (8-12 Hz): These waves occur when we’re relaxed and focused, helping us remain focused, learn new things, and maintain a feeling of well-being.
Beta Waves (13-38 Hz): When you’re alert and thinking, these waves are present. They help keep you alert, improve concentration, sharpen visual acuity, and raise IQ scores.
Low Beta Waves (12-15 Hz): These waves occur when your brain is engaged but not overly anxious or excited. They may be especially beneficial for individuals suffering from attention-deficit/hyperactivity disorder or depression.
Gamma Waves (38-100 Hz): These waves are the fastest of all brainwaves and they occur when you are engaged in cognitive thought. They play an essential role in information processing and sensory binding, helping your brain process complex thoughts simultaneously.
These waves are linked to high levels of intelligence, creativity, compassion and natural feelings of contentment. Unfortunately, they may be lacking in some people which can lead to learning difficulties, diminished mental processing or cognitive decline.
