The Relationship of Mobile Phone Usage to Sleep Length of Students


Background of the Study

According to the Global System for Mobile Communications (GSMA) real-time intelligence data, there are now over 8.17 billion mobile connections worldwide. It exceeds the average world population of 7.71 billion indicated by United Nation digital analyst estimates. The total world population that are now unique mobile subscribers is about 66.53% and the Philippines is in the twenty-first rank with 27.20% mobile users with the total current population of 105,341,000 in which 28,627,000 of the raw smartphone penetrations ranked by the numbers of users within each market.

CITATION How191 l 1033 (How Many People Have Phones Worldwide? n.d.)In relation with this, several findings in 2017 shows that an average American adult spends around two hours, fifty-one minutes on their mobile phones per day CITATION Tex17 l 1033 (Text Request, 2017). Considering the convenience these gadgets could offer, it seems to affect the length of time people utilize it worldwide. Additionally, Statista Research Department (2016) have shown a forecast of the average number of mobile phone users in the Philippines from 2014 to 2020.

Based from this, there would be 74.2 million users for 2019. One reason behind this is the mere fact that the activities linked to technology, specifically mobile phones, increase over time.

It has also been pointed out that communication, entertainment, business transactions, jobs directly related to mobile phones, and travelling are the most common reasons why people use their phone often CITATION GDe19 l 1033 (Geo, 2019).

This tempts the users to utilize it more out of habit. Additionally, Twenge (2017) stated that most mobile phones emit blue light which simulates daylight, which in return inhibits the melatonin (a hormone that helps us fall asleep and stay asleep) production of the brain. This becomes the reason why the internal clock of the body, also known as the circadian rhythm, suppresses the release of this sleep-inducing hormone. This is caused by the short wavelength, artificial blue light that is being emitted by the gadgets utilized. The more people use these gadgets, the more it is difficult for the user to sleep. Furthermore, usage of mobile phones before going to sleep reduces the onset of rapid eye movement (REM) sleep which then compromises the alertness of the person in the morning. Continuous habit of this activity accumulates to a significant chronic deficiency in sleep. CITATION Why19 l 1033 (Why Electronics May Stimulate You Before Bed, n.d.)When it comes to reasons why students use their phones, Vorderer, et. al (2016) stated that with the availability of mobile smart devices, many adolescents have developed the habit of being online and connected with other users almost all the time. Furthermore, they found out that smart device usage behaviors at night and behaviors in various social situations during the day indicate that being connected to others seems to be more relevant to the students than browsing the web. Moreover, the participants expressed strong emotional responses about a temporary loss of Internet access. This only shows how dependent the adolescents are in using their smartphones.

With the increasing dependence of people in using their mobile phones, it shows its own benefits and consequences. One important factor that is affected by this is sleep. Sleep is essential for a person. It is the time where the body and mind renew, repairs and develops CITATION Kar17 l 1033 (Karadağ, 2017). Moreover, an adolescent should have an average of eight to ten hours of sleep per night CITATION Hir15 l 1033 (Hirshkowitz, et al., 2015).

Mobile phone usage deprives people from having sufficient sleep. For students, it is necessary for them to get a proper sleep for their mind to function well and show great academic performance CITATION Kwo13 l 1033 (Kwon, Lee, Yoo, & Park, 2013). Excessive use of mobile phones can also result to tiredness, headache, dizziness and sleep disorders. In addition, it can also affect the cardiovascular system, central nervous system, and hormone levels CITATION Sch09 l 1033 (Schüz, Waldemar, Olsen, & Johansen, 2009).

Meanwhile, this study will go deeper between the relationship of mobile phone usage to the sleep length of students. It is important to have a better understanding of using mobile phones, something that is already considered as part of our daily lives, and sleep, which is an essential need of our body.

Statement of the Problem

This study will aim to determine the correlation between mobile phone usage and sleep length of Ateneo de Naga University Senior High School (ADNU-SHS) Science, Technology, Engineering and Mathematics (STEM) Grade 12 students. Specifically, it will seek to answer the following questions:

How long do the respondents use their phones daily?

How long do the respondents sleep daily?

What time of the day do the respondents use their phones?

Is there a correlation between the length of mobile phone usage to the length of sleep?

Scope and Delimitation

This study will focus on the relationship between the length of mobile phone usage and sleep length among Senior high school students. Meanwhile, the respondents of this study will be limited to the Grade 12 STEM students of ADNU-SHS who use their mobile phones regularly.

Definition of Terms

To eliminate ambiguity in the discussion, the following terms will be defined:

  • Technology. This is an application of scientific knowledge to the practical aims of human life, or to the change and manipulation of the human CITATION Kar15 l 1033 (Karadag & Samancioglu, 2015). In this study, this will refer to the machine or equipment used by the Grade 12 STEM students of ADNU-SHS that can either affect their sleep length or not.
  • Mobile Phone. It is a portable device for connecting to a telecommunications network in order to transmit and receive voice, video or other data CITATION Mob19 l 1033 (Encyclopedia Britannica, 2019). This will pertain to the gadget used by students which will be analyzed if the usage of it have a correlation with sleep length of the students.
  • Mobile Phone Usage. It is defined as any application of the cell phone as a tool, including talking, text messaging, game playing or the sheer accessibility of the instrument CITATION Sho16 l 1033 (Should Phones Use A Distraction?, 2016). In this study, this will refer to the access or exercise of the mobile phones by the Grade 12 STEM students of ADNU-SHS that can either have a relationship with their sleep length or not.
  • Sleep Length. It refers to how long a person sleep on a daily basis. Sleep is a basic necessity that constitutes almost one-third of the hours in a human's lifetime. It is a state of irreversible unconsciousness where the body and mind are renewed, repaired and developed CITATION Akc18 l 1033 (Akcay, 2018). In this study, it will pertain to the act that the researchers will be highlighting in this study, by means of analyzing the sleep length of the students. Its relationship to mobile phone usage will also be determined at the end of the study.
