| Brainwave Frequency | Associated Characteristics |
|---------------------|---------------------------|
| Delta (0.5 - 4 Hz) | Deep relaxation, sleep, healing, unconscious mind |
| Theta (4 - 8 Hz) | Creativity, intuition, memory, learning, sleep, healing |
| Alpha (8 - 13 Hz) | Relaxation, meditation, memory, learning, creativity, reducing anxiety |
| Beta (13 - 30 Hz) | Conscious thought, mental activity, anxiety/excitement, movement, self-control, REM sleep |
| Gamma (25 - 140 Hz) | Cognitive functioning, concentration/focus, creativity, positive mood states, increased brain activity, neurostimulation/meditation |
| Brainwave | Frequency | Characteristics | State of Mind |
|-|-|-|-|
| Gamma | Above 30Hz | Bursts of insight, high-level processing | Hyperconscious
| Beta | 12-30Hz | Alert, focused on outer world | Active thinking
| Alpha | 8-12Hz | Relaxed, inward focus | Light meditation
| Theta | 4-8Hz | Dreamy, imaginative | Deep meditation
| Delta | 0-4Hz | Deep dreamless sleep | Unconscious
- Children have more Theta and Delta brainwave activity as their brains focus on the inner world
- Stress produces incoherent brainwaves
- Meditation creates synchronized, coherent brainwaves

Delta waves are the slowest and are associated with deep sleep, healing, and regeneration[10]. Theta waves are related to light sleep, relaxation, and meditation[10]. Alpha waves are linked to relaxed wakefulness, daydreaming, and creativity[10]. Beta waves are connected to active thinking, focus, and problem-solving[10]. Lastly, gamma waves are the fastest and are associated with high-level cognitive functioning, perception, and learning[10].
