Brain Waves Overview

Humans exhibit five distinct brain wave types: gamma, beta, alpha, theta, and delta, each with specific frequencies and roles.
Brain wave patterns can be recorded using an electroencephalograph (EEG).
The ability to transition between brain wave frequencies is crucial for managing stress, focusing, and sleep.

Gamma Waves

Frequency range: 40 Hz to 100 Hz (Highest frequency).
Associated with higher cognitive tasks, learning, memory, and perception.
Optimal for binding sensory experiences and involved in REM sleep.
Low gamma activity linked to learning disabilities and mental challenges.
Excessive gamma can result in anxiety and stress, while insufficient gamma can contribute to ADHD and depression.
Can be increased through meditation.

Beta Waves

Frequency range: 12 Hz to 40 Hz (High frequency).
Dominant while awake; support conscious thought, logical reasoning, and task completion.
Excessive beta activity can lead to stress, anxiety, and difficulty relaxing, while too little can result in daydreaming and poor cognition.
Stimulated by caffeine and other stimulants.
Essential for focus, memory, and problem-solving.

Alpha Waves

Frequency range: Bridges conscious and subconscious states between beta and theta.
Plays a role in relaxation and mental coordination.
Typically present during calm, relaxed states, promoting creativity and stress reduction.
Balances higher frequency activities of beta waves and lower frequencies of theta waves.

Theta Waves

Frequency range: 4 Hz to 8 Hz.
Linked to deep relaxation, meditation, creativity, and emotional connection.
Often present during light sleep and REM, aiding in memory consolidation.
Inappropriate dominance can lead to daydreaming or lack of focus.

Delta Waves

Frequency range: 0.5 Hz to 4 Hz (Lowest frequency).
Associated with deep sleep and restorative processes.
Crucial for healing and regeneration, as well as immune system support.
Excessive dominance could indicate issues with memory or cognition.
