Recent studies suggest that blue light exposure can impact human circadian rhythms. this suggests that blue light disrupts the function of the gland(s).

pineal

Explanation:

The pineal gland is a small structure located at the posterior end of the third ventricle, above the diencephalon roof, connected to it by small branches, right in the center of the human brain.

There is controversy about the functions attributed to the pineal gland. However, it is known to be fundamental in contributing to various cycles considered vital in the body, such as the sleep cycle and the regulation of sexual and reproductive efforts and circadian cycles in general.

Therefore, if exposure to blue light can affect human circadian rhythms. This suggests that blue light disturbs the function of the pineal gland.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
