Effect of Blue Light Emissions on Sleep Quality in College Students Eleanor Hatton, Ada Laurer, Lily Stemberger, & Sophia Stil a Research Methods Project supervised by Dr. Laura Wilson (Fall 2021) Laurer-poster check out these “elevator” talks from each group member
Those of you who took me for Biological Psychology know that I am very interested in this study! I know that much of the theory on how light impacts melatonin release supports the idea that blue light exposure would disrupt sleep quality, so your findings make sense. However, since you used a correlational analysis to assess the relationship between device use and sleep quality, you do have limitations to inferring that causal relationship from what you collected. Can you envision any other explanations for this relationship that might involve sleep quality being the causal variable instead of device use – or even a possible third variable that might help to explain the relationship?
I found this study to be not only interesting but also extremely useful to our current situation. As college students, we are always using blue-light emitting devices. Hearing that excessive use of these devices can be causing sleep problems is very concernig. I think it is awesome that significant results came out of this study and it could definitely be used to advocate for every college student to own a pair of blue light glasses.
I thought that your study was especially relevant to not only our society’s increased use of technology, but the implications that the results have for college students. Do you think there could have been any other contributing factors concerning quality of sleep?
Interesting study! Blue light is something that is talked about a lot in psychotherapeutic treatments for sleep difficulties (e.g., CBT for insomnia). Do you think it’s also possible that people who have a hard time sleeping are more likely to use blue light-emitting devices at night? How could you design a study that looks at the direction of this effect (blue light —> poorer sleep quality vs. poor sleep quality —> more blue light)?
Also, Ada and Sophia, I love the stats interpretations ☺
Good job guys! I think this is a really interesting topic especially among college students because phone usage is so high. I’m glad you guys were able to support your hypothesis!
Good job on your research and presentation! This was a very relevant study for us to see and interpret as college students ourselves, so keeping this in mind and maybe applying less blue light device usage before bed would be very beneficial to college students. I’m also curious if any of your participants had specialized things to minimize blue light, such as glasses or a night setting on their device? Good work!
I found this project very relevant and useful!! Bow, nearly all college students use our devices to do homework, for entertainment, etc. This study reminded me that I should try to limit my use of blue-light emitting devices when it is time for me to go to sleep.
This was a really interesting study! I think your poster was clear and laid out well, making it easy to follow the information you presented. I think this topic is relevant to today’s world because college students are so consumed with technology for school and in their social lives. I think it would be interesting to see the outcome of this study if it was replicated with younger kids! Will growing up with technology and constantly being on blue light emitting devices have an impact on a child’s sleep quality?
This is a very interesting topic to conduct a study on! Nowadays, there is a lot of talk in the news and media about blue light causing problems in your sleep cycle. I think that your data is a really good start on combatting the facts behind this. I really liked how you structured your poster! It was very easy to follow and was not too much thrown at you! You guys did a really good job!
This study is very impactful and important especially since most college students, and students, in general, spent the majority of the last two years online doing school work. We can see from your project and also past research that blue-light impacts how we learn and sleep. I know for me being a contact wearer that looking at screens hurts my eyes and daily functioning if I am looking at it for too long throughout the day.
I thought this study is extremely relevant, not only for college students but for even younger individuals who are growing up with phones at an early age. I am glad the results showed significant results because it’s such an important topic. Teaching students that decreasing the use of blue light emitting devices may help them with sleep. College students especially complain consistently about sleep issues and this is most likely it! Overall this was a great study, you all did a great job.
Nice job! I believe more studies about technology affecting the youth in sleep, mental health, and development should be an upcoming type of research. Technology changes so rapidly, but we as humans cannot keep with it, so I want to know how it is affecting us. Do you think if you had a control group that did not use blue light devices for an hour before bed, this would show a greater significance of the impact blue light use has on sleep? Thank you so much, and great job with your study!
Great job, your study was extremely interesting and engaging! This is such an important topic as so many people are constantly absorbing blue light through their electronic devices.
I really enjoyed learning about your study and wondered if the results for the blue light emissions would have a higher impact on sleep quality if tested on either younger or older individuals. Your study was very easy to follow and the poster was very easy to read and understand. You all did a great job, overall!
