Audio-Visual Stimulation (AVS) is a scientifically validated device-based method for changing, balancing and safely normalising the brain's excitation and inhibition processes. Using glasses with built-in LEDs and headphones, specific rhythms of light and sound pulses are delivered to the brain.
By changing the rhythm and other parameters of this natural sensory stimulation, AVS gradually encourages the brain towards situationally appropriate states — such as deep relaxation, sleep, calm concentration, or energisation of the nervous system.
AVS increases blood flow to the cerebral cortex, boosts glucose metabolism in the brain and stimulates the release of beneficial neurotransmitters — without the negative side effects associated with medication.
Therapeutic Applications of AVS
Due to chronic stress, neurotransmitter imbalances or poor nutrition, the brain may be unable to adapt its level of arousal. DAVID AVS devices help the brain exit these problematic states by gradually encouraging a shift in the frequency of dominant brain rhythms.
The method has been proven effective for:
- Anxiety
- Insomnia and sleep disorders
- Chronic stress — for relaxation and recovery
- Migraine and tension headaches
- Attention deficit and concentration problems
- Chronic pain
- Overcoming addictions
- Early-stage dementia and cognitive decline in older adults
What Does a Session Feel Like?
Typically, after 6 to 8 minutes into a relaxation or sleep programme, most users report:
- The quieting of inner dialogue and distance from anxious thoughts
- Reduced muscle tension and a sense of groundedness
- A pleasant warming of the palms and feet
- Slow, deep, diaphragmatic breathing
- Feelings of deep relaxation, contentment and peace
- Visual imagery, colours and light patterns
A key goal of AVS is to create a dissociative state — a distancing from thoughts and bodily sensations — similar to deep relaxation. The restorative benefits of this state for the body, brain and psyche are what make AVS so valuable across such a wide range of health challenges.
