As children spend more time in front of computermonitors, they typically spend less time in physical activities. According toCNN Health(2017), children up to age 8 spend an average of 2 hours and 19minutes every day on screen media and for 8- to 12-year-olds, the average timespent using screen media every day was 4 hours and 36 minutes, so children whospend a great amount of time on the Internet also engage more in othersedentary behaviors. The sedentary lifestyle associated with computer usage canbe a prime risk factor for obesity, according to clinical psychologistKaleyvani Geeseeny Sawnmy, author of “The impact of Internt use onChildren/Adolescent”. In a study published in the PMC, it was discovered that those who spent the most time on acomputer were 1.5 times more likely to be overweight and 2.5 more likely to beobese than those who did not use a computer at all.
Even those childrencomputer users who had high levels of physical activity were 1.86 times morelikely to be overweight or obese than people who spent no time on computers.The Internet not only contributes to physical inactivity but commercialsand other programs also encourage us to eat more. It takes away from the timechildren spend on physical activities and also leads to increased energy intakethrough snacking and eating meals in front of the computer. Those habits of”sit time” and “snacks”, and also product advertisements online, influencechildren to make unhealthy food choices.
Furthermore, computer use is linked toboth repetitive motion injuries like carpal tunnel and eye strain. According toa survey which was mentioned in “Internet Use and its Impact on IndividualPhysical Health”, Internet users commonly complaint about dry eyes(73.7%),declining eyesight(64.1%), cervical pain(48.1%), and other things. The Internet,on the other hand, affects on the student’s academic performance.
For instant, onlinegames or Social media sites totally distract children from studying. Instead oflistening carefully what teachers say in class, youngsters often think or chatwith their friends about how they can improve their ability in the games orwhere are they going to hang out in their cyber world and so on. Moreover,after school, they just go straight to the computers, ignoring their homeworkand lessons to review, letting their grades lower more and more. Furthermore,teenagers may use the Internet to cheat during the exams. According to the datafrom a survey about using cellphone to cheating in the exams, 45% of students are believed to use the cellphoneto access the Internet and 20% admitted that they’d already done this.
