Artificial lights that appear on mobile phones and tablets can causes sleep deprivation in modern humans. It messes with our sleep period, push us to be awake by turning our bodies that it’s actually daytime. Failing to get sufficient sleep can lead us to lack of concentration in everything we do, can affect us also to depression and personal changes.
For young children and teenagers, lack of sleep can happen to poor academic performance and attention dysfunctions. Deep sleep is essential as it is the time when our body restore cells and repairs damage suffered during the day. Using the handsets before bed causes people to take longer to reach the deeper stages of sleep and to spend less time in them.
According to Dr. Chris Idzikowski, director of the Edinburgh Sleep Centre, “There is now more than sufficient evidence from a large number of reputable investigators who are finding that smartphones exposure an hour before sleep adversely affects deep sleep.”
Some were exposed to radiation that mimicked what a person receives when using a smartphone. Radiation may activate the brain’s stress system, making people more alert and less able to fall asleep, according to Professor Bengt Arnetz. He added: “We find an effect from mobile phones from exposure scenarios that were realistic. This suggests that they have measurable effects on the brain.”
