Sleep Frequency Chart (Hz)

The complete breakdown of sleep-related frequencies and what they do

Frequency (Hz) Brainwave Type Sleep Stage Best Use
0.5 - 1 Hz Deep Delta Deepest Sleep Severe insomnia, maximum restoration
1 - 2 Hz Delta Deep Sleep (Stage 3) Physical healing, immune boost
2 - 3 Hz Delta Restorative Sleep General sleep improvement (RECOMMENDED)
3 - 4 Hz Delta/Theta Border Sleep Onset Falling asleep faster
4 - 6 Hz Theta Light Sleep / REM Dream enhancement, relaxation
6 - 8 Hz Theta Pre-Sleep Relaxation Calming racing thoughts, wind-down

How Sleep Frequencies Work

Understanding the science behind Hz and sleep

🌊

Brainwave Entrainment

Your brain naturally synchronizes with external rhythmic stimuli. When you hear a 2 Hz binaural beat, your brain shifts toward that frequency - the same frequency as deep sleep.

📉

Gradual Frequency Descent

The best approach is to start at 6-8 Hz (relaxed wakefulness) and gradually decrease to 2 Hz (deep sleep), mimicking your natural sleep onset process.

🔄

Sleep Cycle Support

Throughout the night, your brain cycles through frequencies. Low-level Delta audio can help maintain deeper sleep phases and reduce nighttime awakenings.

⏰

Circadian Rhythm Alignment

Using specific frequencies at consistent times helps train your brain's internal clock, making it easier to fall asleep at your target bedtime.

Frequently Asked Questions

Common questions about sleep frequencies

What frequency (Hz) is best for sleep? +
Delta waves at 2-3 Hz are optimal for deep sleep. This frequency matches your brain's natural deep sleep state (Stage 3 NREM). For falling asleep, start at 4 Hz and gradually decrease to 2 Hz.
What Hz is deep sleep? +
Deep sleep occurs at Delta frequencies between 0.5-4 Hz. The deepest, most restorative sleep happens at 1-2 Hz. This is when growth hormone is released and physical healing occurs.
Is 432 Hz good for sleep? +
432 Hz is a carrier tone frequency, not a brainwave frequency. For sleep, you need Delta waves (0.5-4 Hz). 432 Hz can be used as a pleasant carrier tone with Delta binaural beats layered on top.
How long should I listen to sleep frequencies? +
Listen for 20-30 minutes as you fall asleep. For full-night support, you can play Delta frequencies at very low volume throughout the night. Set a timer if you prefer silence after falling asleep.
What Hz helps with insomnia? +
For insomnia, start with 4-6 Hz Theta to calm an overactive mind, then transition to 2-3 Hz Delta. The gradual decrease helps your brain naturally move through sleep stages rather than jumping directly to deep sleep.
