Wellbeing for a person overall is key to growth both physically and mentally, and sleep is one of the main sources of energy to keep a person’s wellbeing consistent. A person’s physical and mental development depends substantially from their teen to young-adult years. Furthermore, sleep is universally agreed upon to be beneficial no matter the person. One reason for this might be the belief that a good night’s sleep is the foundation for good performance (Silvani et al., 2022). Blue light is far more accessible in today’s world than before, and because of that, it is a versatile tool, and may be used for many different purposes.
The surge of device usage in the modern world has led to multiple differences in human function, mainly being sleep. The media and many other sources consider the negative outcomes of blue light, yet the positive outcomes are usually left behind. The goal of this study investigated how prolonged exposure to blue light impacts sleep quality in teenagers and young adults.
Google Scholar and PubMed were the two main search engines used to research through a boolean search of “((blue light) AND (sleep) AND (high school))” and “OR ((college) AND (young adults)”, giving 18,728 results. After screening and eligibility, ten articles were selected.
Ten articles were selected after general search and screening. The majority of selected articles indicated that both sleep quality and duration increase with lower amounts of blue light. Similarly, literature review indicated that greater amounts of blue light increased alertness, sleep latency, and cognitive functioning.
Blue light has rewarding benefits as evinced by positive effects on cognitive function. However, there appears to be a tradeoff, as blue light exposure can have negative effects on sleep quality, duration, and sleep efficacy.
