Restful Mind (Part 3) - The Soothing Benefits of Delta Brain Waves

You've been asleep for about an hour. You've slipped beyond the realm of dreams into deep sleep.

What Delta brain waves feel like

Your body is completely still and deeply relaxed. From this place, you undergo deep restorative healing, ready to feel refreshed when you wake up.

This is your brain on Delta waves.

When Delta brain waves are dominant, you’re in a state of deep restful sleep.

Delta brain waves occur naturally during deep dreamless sleep.

What are Delta brain waves?

Delta Brain Waves: 1-4 Hertz

Your brain is made up of billions of neurons that use electrical signals to communicate.

When neurons fire together to send signals to other neurons, the resulting patterns are known as brain waves.

Brain waves are measured by their frequency per second, or in Hertz (Hz). And there are five types of brain waves that range from very slow to very fast.

Delta waves are the slowest.

The frequency of Delta brain waves are between 0.5 and 4 Hertz. This means Delta waves peak 0.5 to 4 times per second.

Benefits of Delta brain waves include:

  • deep, restful sleep
  • healing and pain relief
  • neurological regeneration

Types of brain waves

Delta brain waves are just one kind of brain wave.

There are five types of brain waves, each with a different frequency range and unique benefits. From slowest to fastest they are:

Brain WaveFrequencyBenefits
Delta0.5 - 4 Hzdeep, dreamless sleep
Theta4 - 8 HzREM sleep or deep calm
Alpha8 - 12 Hzcalm focus or relaxation
Beta12 - 30 Hzalert and focused
Gamma25 - 100 Hzspike during active problem solving,
information processing and learning

Delta brain waves and deep sleep

When you’re producing Delta waves, you’re in a state of deep, restorative sleep. Which means Delta brain waves help you to have good quality, healing sleep.

Delta waves may also be responsible for greater levels of calm. One study found that boosting Delta waves helped reduce anxiety in pre-operative patients.

By boosting your Delta waves, you might also experience deeper sleep, neurological regeneration and greater calm.

Can you increase Delta brain waves?

Yes you can.

You can activate Delta brain waves through neurofeedback - a specialised brain training program where you try to consciously induce specific brain waves.

However, an easy and effective way to increase Delta waves is by listening to meditones®.

Because meditones help entrain your brain.

What is Delta brain wave entrainment?

Entrainment refers to the synchronisation of organisms to an external perceived rhythm.

Your mind and body integrate musical patterns in unison with your own biological rhythms - like tapping your foot along with the beat.

But some entrainment rhythms are more subtle.

Music can entrain your heartbeat, your hormones and even your brain waves.

Both brain waves and sound waves are measured in Hertz. Which means we can use sound to stimulate or entrain specific brain wave patterns.

How do meditones entrain Delta brain waves?

When two slightly different frequencies of sound combine, they create a humming vibration. And when you listen to this vibration in headphones?

It creates a fascinating auditory perception called binaural beats.

Your brain responds by creating calm brain waves. Similar to ones you produce during relaxation and restful sleep.

Which means, when you listen to a vibration of 2Hz, your brain will produce brain waves of 2Hz.

Brain waves that are at a frequency of 2Hz are in the Delta range.

So by listening to binaural beats at 2Hz, you’ll start to produce Delta brain waves and sink into deep sleep. Effortlessly.

Meditones are binaural beats combined with beautiful ambient music.

This makes meditones a fantastic option for autistic, ADHD or other neurodivergent people who may struggle with traditional forms of meditation.

Because meditones make you calm without you having to do a thing.

Just listen with headphones, and the meditones effect occurs naturally and easily.

By combining binaural beats and calming ambient music? You can quickly reap the benefits of Delta brain waves, such as:

  • deep sleep
  • healing & rejuvenation
  • greater calm & wellbeing

Inside the Restful app we have hours of calming Delta meditones.

You can easily filter by brain wave on the Explore page.

Takeaway

Electrical activity is always occurring in your brain. But Delta brain waves are dominant when you are in deep, restorative sleep.

You can boost Delta brain waves when you listen to meditones, which can help you have deeper sleep and feel calmer.
