Your brain vibrates, too, and it’s happy doing so. As a lifelong performing musician, I’ve been working for a long time with the vibrations you can hear, feeling the strain of pitches that produce more waves when played together, creating a harsh sound or feel, and those that vibrate together. The lowest notes we can hear vibrate at a very low frequency. Our brains like to vibrate like that for rest and healing, but there are also ways to produce those waves between different notes. Specific pitches also have a greater effect on specific parts of the physical and energetic body. I use bowls and gongs, instruments, and my voice. Not just the words I say, but the timbre is important.

Delta waves are the lowest (slowest) frequency waves we find present in the brain during deep, dreamless sleep, and we don’t hear them consciously. Theta waves are also quite low and slow, but approach a more audible range. Theta waves are present when we’re drifting off to sleep, when the world is fading away, and sometimes in meditation, bridging the conscious with the subconscious. Alpha waves come next, and are associated with the creative dreamers and great inventors of the world. Beta waves are where most people live their lives when we’re in a state of doing and reacting. Gamma waves occur when we are in an alert flow state and create a connection across different parts of the brain, allowing us to process very quickly. There is some emerging evidence that this activity also aids in immune function.

Among all brain wave patterns, delta waves show the strongest correlation with physical healing and restoration processes. These slow-frequency waves dominate during the deepest stages of sleep, when the body prioritizes repair and recovery functions. Delta waves have been specifically linked to several crucial healing mechanisms within the body.

During delta-dominated states (read: in deep sleep), tissue regeneration and cell growth increase significantly. This makes delta waves especially important for recovery from injuries, surgeries, or any condition requiring cellular repair. The slow oscillations of delta waves create an environment conducive to the body’s natural healing abilities, allowing resources to be directed toward restoration.

The release of essential hormones for healing and rejuvenation also occurs predominantly during delta states. While in deep delta sleep, the body produces increased amounts of melatonin, a powerful antioxidant that protects cells from damage, and DHEA, often referred to as the “youth hormone” due to its role in maintaining cellular health. These hormones play vital roles in the body’s recovery processes and immune system functioning.

Research shows that delta brain waves help improve immunity by increasing the production of cytokines, proteins that regulate immune response and combat infection. This makes delta waves crucial for recovery from illness. Similarly, delta waves are associated with reduced inflammation, which further supports recovery from injuries and inflammatory disease.

For all that delta waves support the physical being, theta waves support neurological function and psychological health. Theta brain waves govern the part of our mind where memories and feelings are stored and where beliefs and behaviors are formed, so theta states are super useful for psychological healing, processing trauma, relieving anxiety, and reframing negative thought patterns because the mind is more receptive to suggestion and change. Our work uses these waves patterns so you can feel calm, focused, and healed.
