Personally no matter how much I sleep, I always find myself super exhausted when I wake up in the morning. I tried to do some research to make sure I take full advantage of my sleep.
I’ve gotten into this bad habit of falling asleep while using my phone in bed and waking up with my phone right by my pillow. My mother always told me this was bad for me and I always acknowledged, but never really considered why. After lots of research I am very surprised with what I found.
In a study conducted it was found that people who use their phones after they turn the lights off, are significantly more tired and have side effects.
The null hypothesis in this study is that there is no relationship between using your phone past the time you turn your lights our and how tired you are. The alternative hypothesis is that there is a relationship between how tired you are and if you used your phone after the lights are out.
This experiment consisted of 258 students to do a stratified random sample. The participants had a mix of males and females of different marital statuses, occupations and ages. The people were prompted to answers questions about who they slept and felt. The results were amazing!
The relationship between cell phone use after lights out and how tired a person was resulted in p-value of .04.
The relationship between cell phone use after lights out and stress, the quality of sleep resulted in a p-value of .001
In both of these cases, you would reject the null, and accept the alternative hypothesis which was that there is a relationship between how tired you are and if you used your phone after the lights were out.
It is important to note that the file drawer problem can be ruled out because there was a finding that resulted in a p-value of 0.23. This finding was the relationship between using cell phones after lights out and sleep quality. In this case you would accept the null hypothesis which goes against the other results, and rules out bias findings.
A logical person from these finding can take steps to better their sleep. One way you could better the way you sleep is by not going into your bedroom until you are completely done using your phone, or not turning off the lights until you are completely done using your device. Another way to help you sleep better is to turn your phone off completely when going to bed, put it on airplane mode, or consider charging it on the other side of the room.
