Protect your hearing. There are no therapies currently available to reverse loss.

Hearing loss…
+ increases your dementia risk up to 5x
+ coincides with 30–40% faster brain shrinkage

Less auditory input leads to less stimulation, so brain regions tied to sound and cognition atrophy from underuse. This ‘use it or lose it’ effect is real and permanent.

Once those hair cells in your inner ear are gone, they’re gone. Cochlear implants help, but they don’t restore natural hearing. Regenerative medicine is years away from reliable use.

My protocol:
+ Download a decibel meter app
+ Protect your ears at XX dB+
+ Get custom-molded earplugs
+ Carry earplugs everywhere
+ Avoid prolonged exposure to noise over XX dB+ (2hr+)
+ Check your hearing regularly (with a specialist, or using a validated app)
