    cancer lesions” (88). Blue light is a natural signal to the brain that it is daytime; therefore, it is time to be awake and productive in society. However, Ford also warns that the amount of blue light exposure can be detrimental to health because it affects the production of melatonin in the brain. Barone states, “People normally produce melatonin in the evening starting a few hours before bed as part of our natural circadian rhythm” (10). Melatonin is a sleep-inducing hormone produced by the pineal gland in the brain. When secretion is inhibited by the body -- because it still thinks it’s daytime with the excessive blue light emittance -- the natural sleep cycle is disrupted (Komada et al 320). The natural sleep cycle, or circadian rhythm, is defined as “the biological clock that keeps us in sync with this daily cycle” (Barone 10). It allows the body to respond to daylight in order to differentiate between night and day (Barone 10). Ford mentions, “Melatonin is secreted by the pineal gland in the presence of darkness” (88). Therefore, with the increased light at night and right before bed people are not receiving good sleep because their brains are not producing as much melatonin due to increased blue light emittance. Likewise, “Blue light exposure at night has been shown to affect the quality of sleep” (Ford 88). This suppressed melatonin production could have serious consequences: it could cause developing tumors that can cause cancers (Ford 90). The short-wavelength…
