Electronic Devices Keep You Up at Night

Question

Electronic devices produce blue light. Blue light is short-wavelength enriched light that has been proven to slow the production of your natural melatonin release. Blue light can also affect the quality of sleep you are getting. Children are most affected by the lack of sleep from blue light, because their brains are still developing.

I found this when researching issues that can affect sleep. I found numerous other articles that also supported this claim. This article was written by Danielle pacheco and medically approved by Kimberly trong.

I thought your fact check was really good. I thought you provided a great source to go with the claim. The source provided very helpful evidence to why using electronic devices at night isn't good for someone's health, the article also provided tips on how to solve this issue which I thought was a great addition to the article.

---

I agree with this fact check and appreciate the explanation, however it would've been good to know a few more of the other articles you found that prove this claim just to add extra supports. I liked how you went into more than just whether it was right or wrong but gave an example.

---

I like how you have multiple sources have proven that using electronics before bed can make it harder to fall asleep. This is because the blue light emitted from screens reduces the body's natural production of melatonin, the hormone that regulates sleep.

---

This is a good claim due to the way its being backed up and the evidence that was brought into your claim with your sources good job!

---

I agree with this statement that electronic devices can disrupt sleep patterns due to the blue light and how it stimulates our brain making us more alert and awake. The article provided was clear and had good details to support the statement. A clear understanding on the science behind how it affects us and ways how we can prevent technology disrupting our sleep routine.

Answer 1

This is shown to be true. Multiple reputable sources, most with .org domains, have said this is true. The blue light from screens can decrease your body's natural melatonin production. This is why it is recommended to turn off devices about 45 minutes before you go to sleep. Many doctors have backed this claim.

The claim that I have chosen to fact check was that electronic devices keep you up at night and I completely agree with this claim as how i had personal experience with it. As how there has been a whole bunch of studies and surveys that all agree with the positive that electronics do keep you up when you are just laying down in bed. As I readed the article, this source is pretty reliable.

---

I think you showed the importance of getting rid of blue light before sleep, and it's good that you cited reputable sources like UCLA Health and Cleveland Clinic. I recommend you included specific details from these sources to support the claim even more.

Answer 2

The article claims that “Electronic devices keep you up all night” while this article talks about the waves and blue light that electronic devices produce, it doesn't give any proof of a research conducted by any source. Through my research I found a study conducted at a Vietnamese university where they found that smartphones are the most used devices among the students in the Vietnamese university and that the “Ed usage within 2 hours before bed time was associated with poor sleep quality” (“Electronic Device Use before Bedtime and Sleep Quality among University Students”). This proves the claim of the article, as I looked at this study I also found many more studies related to Ed usage having a strong connection with poor sleep.

Comments

I appreciate you citing a study to back this claim! That being said, you have not provided any of your used sources, including the aforementioned study. Doing so will make your fact check quite a bit stronger!

---

This was a helpful answer to add since many people are brushing over the lack of specific research in the article. However, I think it would be helpful to add a link or a citing to the source that you have mentioned. Otherwise, it's hard to verify whether this is true or not.

---

I think this response was very helpful just due to the fact that you supported the original reporters claim with evidence. I appreciate how you used a study as evidence, although I do wish that you provided us with a link so we could have looked into this study further and easier.

---

This is a great fact check that makes sense, but without providing your sources, that does make it less credible. If you add your source I think it will add a lot of reliability to your fact check and make it more believable.

---

This was a very helpful response, you gave credible sources that prove the original statement.

---

I appreciate the citation you used to back your claim and allows me and others to check the veracity of the claim. I would have loved to see a claim from an article and a link posted to the article so we can check the authority of the writer. Other than that good job and keep up the good work.

---

This is a really good factcheck. I think that you did a great job providing a lot of evidence that supports your claim and adding in text citations to back your claim is very helpful. The only thing that I would add would be a link to the sources that you used so that we can make sure you used a credible source.

---

It's good that you pointed out the lack of research in the article and back up your claim with a study. I recommend adding a link to your sources so we can make sure the source is credible.

Answer 3

Electronic devices can keep you up at night because their blue light suppresses melatonin, delaying sleep. Engaging content also mentally stimulates the brain, making it harder to wind down. Plus, screen time often leads to staying up later than intended.

 "Studies of college students have consistently demonstrated that blue light in the evenings causes both a reduction in melatonin levels and a phase delay in normal secretion patterns."

I agree with your claim and good job giving us the link to all your sources on which you created your claim from. Would have loved to see specifically which article you are referring to in the quote and what makes your articles more credible than others.

Answer 4

This claim is true! Electronic screens emit a blue light that acts like sunlight, and tells the brain it's time to be awake. This stops the brain from releasing melatonin, which is the crucial chemical that helps regulate your sleep cycle and fall asleep. Electronic use before bed has actual become a major public issue, with a significant drop in sleep quality.

I agree that your claim is well-supported by research, as studies have consistently shown that blue light from electronic screens can suppress melatonin production, making it harder to fall asleep and reducing sleep quality. The links you provided further strengthen this argument by highlighting scientific findings on the effects of screen exposure before bedtime. However, I do think that while the blue light plays a significant role, other factors also contribute to sleep disruption, such as engaging content that keeps the mind active or stress-related phone use. Some studies suggest that using blue light filters or night mode settings can help mitigate these effects, though their effectiveness varies. Additionally, behavioral changes, such as limiting screen time before bed or using alternative relaxation techniques, may also improve sleep quality.

Answer 5

when I first saw this I totally agreed with you. in past I have thought the same thing, and have heard of people who don't use their phone even a couple hours before bed. when reading the article you provided it seems as though there has been extensive research for this topic. I read a different article that agrees with you but they also mention ways to reduce the blue light before bed. one way they mentioned is getting blue light glasses or having a blue light filter on your phone. this way you can use it before bed. but overall your topic is very well done and I agree with everything, but try to mention the ways that you can reduce the blue light.

I enjoy hearing solutions to this problem because everyone is bound to use back lit devices in their day to day. One comment I read said that putting away electronics 45 minutes before bed is very beneficial to you sleep quality, but I like hearing that there are other ways such as using blue-light glasses that make it okay to use our devices right before bed even.

Answer 6

This claim is true based on many reputable sources and studies done. The source given seems to be reputable given it is from a .org website and the writer Danielle Pacheco graduated from University of British Columbia with a degree in psychology and Kimberly Truong is a Stanford trained sleep physician I found multiple sources both listed below that agree with this claim which are .org websites and reputable in the world to confirm this claim.

This is a great answer that verifies the original claim through the quality of both the website and writers and utilizes other good outside sources to verify it. Great job!!

Answer 7

This is True using electronic devices at night can keep you up at night. In an article by UCLA Health they state, "Electronic devices like smartphones, laptops and TVs emit an artificial blue light that mimics sunshine." ("Are Electronic Devices Impacting Your Sleep?", UCLA Health). This means that through staring at screens our bodies are perceiving the light to be sunlight which sends light and dark nerve signals to our brains which help us wake up. Because these nerve signals tell our brains to wake up it prevents us from being able to fall into deep REM sleep which according to Dr. Alan Thomas Charly, "It is essential for brain development, memory consolidation, and emotional control." This means that by watching screens before bed you are inhibiting your body's ability to rest and recharge making them keep you awake at night for longer periods of time.

Answer 8

When I look at this article I found that it claims “Electronic devices keep you up all night.” While it does discuss the blue light and waves emitted by electronic devices, it doesn't really provide much concrete evidence from any specific research study. However, I do believe that my research has led me to a study conducted at a university in Vietnam, which could've found that smartphones were the most commonly used devices among students. The study concluded that “electronic device usage within two hours before bedtime was associated with poor sleep quality” This helps us kind of support the article’s claim that electronics can indeed keep you up. Additionally, I found that multiple studies linking electronic device usage to poor sleep. The connection is well-documented—electronic screens emit blue light, which mimics sunlight and signals the brain to stay awake. This suppresses melatonin production, the essential hormone that regulates the sleep cycle. As a result, electronic use before bed has become a significant public health concern, contributing to a noticeable decline in sleep quality.

Answer 9

Research backs up the claim that blue light from electronic devices can suppress melatonin production and impact sleep quality. Studies show that exposure to short-wavelength (blue) light at night can delay sleep onset and reduce sleep efficiency.

For example, a study published in Sleep Advances found that blue light exposure in the evening disrupts melatonin levels and sleep patterns. Another analysis in the journal Sleep found mixed results on whether blue-light-blocking interventions improve sleep, suggesting that some people may benefit more than others.

Answer 10

This has been proven true by multiple reputable sources, many of which are .org sites. Studies show that blue light from screens can reduce your body's natural melatonin production, which can make it harder to fall asleep. That’s why experts recommend turning off devices about 45 minutes before bedtime. Many doctors support this advice as a way to improve sleep quality.
