• Independent variables : Mobile phone use.

• Controlled variables : Age group.



Sleeping disorders have always affected people's lives, performance and productivity. Many causes were beyond these irregularities. Technology was developed to save time, but it seems that it's losing time and health as well. The too much use of mobile phones, e-readers and even computers is supposed to have deleterious effect on our brains and our sleeping cycles. To explore this possible association, we designed a questionnaire on a sample of students (18-23) years old.





Scientific Method

1- The use of Electronic devices including mobile phones before sleep have a direct role in sleeping disturbances.

2- Factors like exposure time and screen brightness can increase this bad effects.


We observed that electronic devices especially mobile phones affect our sleeping cycles and moods.




Test of Hypothesis“Methods”
To test the hypothesis we have designed the following questionnaire, where about students of age group (18-23 ) years old were asked to complete it according to their habits regarding their use of mobile phones and how this would affect them.



To test the hypothesis we have designed the following questionnaire, where about students of age group (18-23 ) years old were asked to complete it according to their habits regarding their use of mobile phones and how this would affect them.



Results
1. Do you usually wake up from sleep during night?





2. How much time you keep looking at your mobile phone before you sleep?





3. During the past week, have you been bothered by:
(a) difficulties falling asleep? (b) repeated awakenings with difficulties going back to sleep?




What is the intensity of your mobile screen brightness?



Explanation
What makes mobile phones cause these bad effects goes back to their light, that stimulates specific cells in the retina which in turn send messages to the brain, so tricking our brains into believing it’s daytime. Then our bodies tend to reduce the release of melatonin hormone ”The sleep hormone” and raise the level of waking hormone, cortisol. The greater deal of blue light emitted from those electronic devices makes them more stimulating than the ordinary light bulbs as the retina is more sensitive to it.
Conclusion
1. The main findings in this questionnaire  suggest that intensive Electronic devices (Mobiles) use can have an impact on mental health among young adults.

2. Intensive mobile phone use enhanced associations with mental health symptoms
