40 Hz (Alzheimer's?)(Pure Tone)

Any donations are so appreciated :) https://cash.app/$VibrantVibes7

40 Hz is believed to enhance cognitive function, improve memory and attention, reduce stress and anxiety, better focus and concentration, and improve sleep quality.

40 Hz stimulation, using light or sound, has shown promise in reducing symptoms of Alzheimer's disease by enhancing brain activity, promoting the clearance of harmful proteins like beta-amyloid, and improving cognitive functions. This non-invasive therapy has been associated with preserved brain volume and better neural connectivity in early studies.

For Alzheimer's it is recommended to listen to 40 Hz for one hour a day. I'm not in the medical field but I've done a lot of research.
(I don't know if it's just a coincidence but when I listened it made my headache go away just a fyi lol)
