Delta Brain Waves: Why They Give You The Best Night's Sleep
You've been asleep for about an hour.
You've slipped beyond the realm of dreams into deep sleep.
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 dreamless sleep.
What are delta brain waves?
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.
There are five types of brain waves that range from very slow to very fast. Delta waves are the slowest.
Imagine you’re watching the waves at the beach. You start counting how many times they crash onto the shore per second.
The number of times the waves crashed onto the shore is their frequency. In science, this frequency is called Hertz (Hz).
The frequency of delta brain waves are between 0.5-4 Hertz. This means delta waves peak 0.5 to 4 times per second.
Benefits of delta waves include deep sleep, healing and 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:
- Delta waves - between 0.5 and 4 Hz, dominant during deep, dreamless sleep
- Theta waves - between 4 and 8 Hz, dominant during light sleep or deep calm
- Alpha waves - between 8 and 12 Hz, dominant when you feel relaxed and idle
- Beta waves - between 12 and 30 Hz, dominant when you're alert and focused
- Gamma waves - between 25 and 100 Hz, dominant when you’re actively involved in problem solving, processing information 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 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. You mind and body integrate musical patterns in unison with your own biological rhythms - like tapping your feet 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?
Meditones are precisely tuned frequencies of sound, that when heard with headphones, guide your brain into effortless calm.
Here’s how they work.
When two frequencies are combined they make a humming vibration. When you listen to this vibration with a pair of headphones, your brain synchronises to that frequency.
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 meditones at 2Hz, you’ll start to produce delta brain waves and sink into deep sleep. Effortlessly.
The technical term for meditones is binaural beats and their results are completely backed by science.
But all you need to remember is that they make you calm without you having to do a thing. Just listen with headphones, and the meditones effect occurs naturally and easily.
Delta brain waves and music
Slower paced music is perfect for inducing a relaxed state of mind. By combining delta meditones and calming music, you can easily begin to reap the benefits of delta brain waves, such as:
- deep sleep
- healing & rejuvenation
- greater calm & wellbeing
Inside the Seekers' Sanctuary we have hours of calming meditones music for delta brain waves. You can easily filter by brain wave on the Explore page. Or check out our Ultimate Sleep Playlist.
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 in turn will help you have deeper sleep and feel calmer.
