Understand the Science Behind 40Hz

The research that’s changing how we approach cognitive decline. Learn why gamma brainwaves matter and how we’ve made this therapy comfortable enough to use every day.

The power of gamma brainwaves

Gamma brainwaves coordinate communication across brain regions. In Alzheimer’s, these waves weaken and fall out of sync, disrupting the signals that carry memory, recognition, and focus. Learn why restoring them matters.

Invisible Spectral Flicker (ISF)

Traditional 40Hz devices use harsh strobe lights that cause nausea and headaches. EVY’s patented ISF technology transitions between two shades of white so smoothly it’s barely perceptible. Same frequency. Zero discomfort.

Understanding the Differences in 40Hz Stimulation

The science behind 40Hz is proven. The difference is whether a device lets you stay consistent long enough to benefit.

Frequently Asked Questions

What is 40 Hz Light Stimulation?

40 Hz light stimulation is a therapeutic approach that involves exposing individuals to light flickering at a frequency of 40 hertz (Hz), where the light blinks on and off 40 times per second. This technique is primarily explored for its potential benefits in treating Alzheimer’s disease. The key aspects of 40 Hz light stimulation include:

Gamma Rhythms Restoration: The therapy aims to stimulate the brain and restore gamma rhythms, which are important for cognitive functions and are often disrupted in Alzheimer’s patients.
Reduction in Alzheimer’s Pathology: Studies have shown that 40 Hz stimulation may reduce the levels of amyloid and tau proteins in the brain, which are hallmarks of Alzheimer’s pathology.
Improvement in Cognitive Functions: Preliminary studies indicate that this therapy may improve cognition and preserve synapses in Alzheimer’s patients.
Non-Invasive Nature: As a non-invasive therapy, it delivers sensory stimulation through light and sound, offering a safer alternative to more invasive treatments.
Potential for Widespread Application: Ongoing research and clinical trials are exploring the broader applicability and effectiveness of this therapy in treating Alzheimer’s disease.
