The mechanism of red light therapy – How targeted light improves hearing
Red light therapy has been used in medicine for decades to promote healing processes in the body—for example, to relieve chronic pain or accelerate wound healing after injuries and operations.
What makes it special is that the light waves penetrate deep into the tissue—including the inner ear, where they stimulate processes that supply weakened hair cells with new energy and improve hearing.
"What happens inside the ear – Activating cells, improving hearing
650 nm red light specifically reaches the hair cells in the inner ear, where it triggers photobiomodulation—a natural process where light energy is absorbed by cells and used to improve their performance.
Central to this process is the increase in ATP production, the main source of energy for cells. This additional energy primarily supports hair cells that have been damaged by age, noise, or poor circulation.
The light also helps to reduce inflammatory processes in the tissue surrounding the hair cells – a common side effect of aging.
Additionally, red light sends regenerative signals that improve cell metabolism, repair damaged structures, and promote overall hearing performance.
This strengthens and improves hearing beyond what the body could achieve on its own.
More clarity for your ears thanks to natural cleaning
In addition to activating cells, the light also supports the natural self-cleaning process of the ear.
It promotes the movement of the fine cilia in the ear canal, which help transport dirt and debris outward.
This keeps the ear clean and healthy, and hearing clear and sharp – for an optimal sound experience in everyday life.
ReHears helps with various hearing problems
With age, hair cells lose energy and resilience, which impairs hearing and leads to symptoms such as tinnitus. ReHears re-energizes these cells and stabilizes overactive signaling pathways.
Particularly effective for:
- Age-related hearing loss
- Tinnitus
- Sensorineural hearing loss
- Noise-induced hearing loss
- Circulatory disorders in the inner ear
This makes hearing clearer and more stable – especially in everyday life, where it is important to understand conversations and consciously perceive sounds.
Studies confirm the effectiveness of ReHears
Numerous studies confirm the effectiveness of 650 nm red light for hearing problems and tinnitus—with no known side effects. ReHears uses this gentle yet powerful technology to re-energize your hearing, stabilize hair cells, and restore balance to overactive signaling pathways.
Give your hearing the support it deserves – and take control of the change yourself. For greater clarity, peace of mind, and quality of life in your everyday life.
