Consistent light exposure has a greater effect than intermittent exposure. [14] In rats, constant light eventually disrupts the cycle to the point that memory and stress coping may be impaired. [15] The intensity and the wavelength of light influence entrainment. [2] Dim light can affect entrainment relative to darkness. [16]
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.
Blue light has a significant impact on numerous physiological processes in human health. [3] The widespread use of blue light in modern technology brings up a concern about the potential consequences of excessive blue light exposure. [4] Such exposure has been associated with disruptions in ocular health, sleep patterns, and well-being. [4] [5]
According to Harvard Medicine, blue light can help boost focus and mood during the day but can disrupt sleep at night and suppress the release of melatonin—the sleep hormone. Blue light has also ...
This is because blue light can suppress the body’s production of melatonin, the sleep hormone, but how much blue light affects melatonin is unclear, Adair says.

Using technology before falling asleep can affect a student's sleep pattern. [13] The blue light that is emitted from the screens of cell phones, computers, and other devices stops the production of melatonin, [13] a hormone that controls the sleep-wake cycle of the circadian rhythm. [13]
