[6] [4] Light seems to have therapeutic antidepressant effects when an organism is exposed to it at appropriate times during the circadian rhythm, regulating the sleep-wake cycle. [ 6 ] [ 4 ] In addition to mood, learning and memory become impaired when the circadian system shifts due to light stimuli, [ 6 ] [ 20 ] which can be seen in studies ...
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device.
Hearing aids can mask or cover up the tinnitus, and many with hearing loss and tinnitus find relief by using hearing aids.

But what the tech giant demonstrated was a renewed focus on health, boasting two “groundbreaking” features on the new Apple Watch and AirPods Pro 2: sleep apnea detection and hearing aid features.
Blue light exposure, particularly in the evening or at night, suppresses the production and release of melatonin. When light stimulates and activates the SCN, [21] the paraventricular nucleus (PVN) of the hypothalamus receives more signals from a neurotransmitter called GABA. GABA is an inhibitory neurotransmitter that aids in controlling ...
