Our generation is addicted to cellphones, so much so that cellphones have begun to rule our lives. Every once in a while find ourselves glued to the screen. For many of us the obsession continues even while we eat or head to the bed at night, we are constantly stuck to it, texting or watching videos into the wee hours of the night. Are we to assume that such a habit comes with no negative consequences or does it show affect slowly and steadily? What about the teenagers who seem to be addicted to their smartphones all the time? According to a study done by Australian researchers at Murdoch and Griffith Universities, late night mobile phone use has devastating effects on teenagers’ mental healthUsing Cell Phone Late At Night May Put Teenagers at Risk of Depression

Funded by the Australian Research Council, it is the world’s first long-term assessment of adolescent mental health regarding late night mobile phone usage. The process was conducted as an annual survey over four years and included 1,100 students from 29 schools. When the subjects began the process, they were in Class 8 of High School. When the programme concluded, they had hit Class 11.

For the study, the researchers examined students’ quality of sleep, along with mood, aggression, coping skills, self esteem and whether they experienced any symptoms of depression. The questionnaires focused on what time of the night students continued to receive or send text messages and phone calls.

“We found that late night phone use directly contributed to poor sleep habits, which over time led to declines in overall well-being and mental health,” said lead researcher Lynette Vernon. “We have demonstrated how poor sleep is the key link connecting an increase in night-time mobile use with subsequent increases in psychosocial issues.”

Around two thirds or 65 per cent of students in Class 8 who owned a mobile phone were reported to use it regularly after “lights out”. When the study concluded four years later, the figure was 78 per cent, finding that “as their levels of mobile phone use grew over time, so did their poor sleep behaviour”, co-author Kathryn Modecki said.

According to Mark Levi, a Sydney-based sleep doctor, the scientific reason why mobile phones can have such a negative influence on sleeping patterns is due to the unnatural light they produce. “Blue light in your bedroom retards your sleeping, it affects your hormones, it affects your melatonin secretions, your insulin secretions, it affects a lot of balance in the body,” Levi told Xinhua on Tuesday.

“So the more you sit in bed and watch TV, play with your tablet, phone and have your phone beeping at 3 in the morning, all these things affect the slow waves of your sleep pattern and will give the person poor quality sleep. Blue light is a real, real problem in the bedroom. It’s a big, huge problem.”

For Levi, the findings of the study are no surprise, “there is no question, no question at all that it’s a growing issue with teenagers, adolescents and the young”, the sleep expert said.

“When a phone is beeping all night or they are watching a screen all night, it’s affecting their sleep a lot and we’re seeing child with sleep patterns that are disturbed and it’s going to affect their attitude, their cognitive skills, concentrations skills, their moodiness during the day.”

Despite the damning findings, Vernon said the answer to solving the problem was not to simply ban teenagers from using their devices but to find ways of promoting better sleep habits to adolescents.
