Celsius causes brain fog

Question

Celsius and other caffeinated drinks can lead to brain fog and fatigue.

Comments

I agree with the claim, but if there were more resources about the actual Celsius drink it would be more credible. I also think if there was a different claim made, the article would be more credible. But the article and claim just don't correlate to each other.

I think that this claim definitely has some truth to it, however since the article does not directly call out Celsius, then that leads me to believe that the person to created this claim may have something against the Celsius drink, or maybe the company, considering that the brain fog comes from the caffiene in the drink, then it wouldn't make sense that other drinks containing caffiene would not also cause brain fog.

I don't agree with this claim at all. Obviously, if you consume too much of something it becomes bad for you. However, Celsius and other energy drinks are made to give you energy and essentially focus on whatever activities you're trying to do.  Celsius is also made with different vitamins and amino acids that help enhance mental clarity and physical performance. Many consumers report increased focus and sustained energy without crashes associated with traditional sugary energy drinks, especially considering that Celsius is made with 0 sugar. If Celsius did lead to brain fog, its products wouldn't be endorsed by so many athletes at both college and professional levels. These are people who's jobs require focus and lots of energy. Rather than blaming energy drinks, I think factors like an individuals diet, hydration levels, and caffeine tolerance .

This claim “Celsius and other caffeinated drinks can lead to brain fog and fatigue.” is found to be true followed by many harmful effects. Firstly when reading the provided article, the writer never actually states the issues being caused are by the caffeine within the Celsius brand themselves. In this case, the author could have gone to extreme assumptions for this claim to persuade the audeince, despite some truth in the statement. It seems that ther eis no direct correlation with Celsius itself rather than caffeine as a whole casuing brain fog within customers. An external article addresses brain fog in general stearing away from even the effects from caffeine. Brain fog is often linked to chronic fatigue syndrome (CFS), which affects about 1 million Americans. (Roche, 2025). Other validated sources address some negative aspects of caffeine intake; crashes, dehydration, and blood sugar irregualries.  Ultimatley, it is determined that although this claim is true, this specific article coverfing the effects of celsius are untrue and are made assumptions.

This claim that Celcius and other caffeine drinks cause brain fog is shown to be true in this article by providing multiple other sources. The article talks about various health risks most concluding in overuse of caffeinated drinks can cause brain fog. The article also provides multiple other reliable sources to back health concerns relating caffeine. Although the article is convincing, the claim could be biased from a personal experience.

Answer 1

The article shows how caffeine can affect the brain, having a direct impact on brain fog. The article cites Vail Health, which suggests that brain fog is caused by poor sleep or fluctuation in blood sugar. Caffeine can impact sleep, but it's not the sole cause of brain fog, as other factors can also affect brain function. The original article was written by a professor from the University of Maryland, and it was reviewed by a registered dietitian. Both individuals are highly qualified, which makes the article more credible. The sources that are cited, Vail Health and Cleveland Clinic, are well-respected organizations. While caffeine might not directly cause brain fog, it can cause dehydration and bad sleep, which do cause brain fog. Not all brain fog is linked to caffeine; consumption can increase the chances of experiencing brain fog due to its non-direct effects. So I would say this fact check is true. 

Comments

I appreciate how much you analyzed the original source, however it may have been good to find another source to back up your factcheck. I still admire that you took into account the information given as well as added your thoughts.

Answer 2

Even though caffeine in the long term can give you more brain fog, according to this article the benefits of cognitive caffeine benefits outweigh the negatives and the article says that caffeine makes you sharper and smarter if you have healthy doses in moderation. But the article says if you abuse caffeine and stay up super late that causes brain fog not caffeine alone. I feel like this article is true because sleep is very important for mental health and cognitive function and if you're not sleeping right that causes brain fog instead of caffeine by itself. 

 

Answer 3

This article purposefully uses a misleading headline in order to try to receive more engagement. It claims that Celsius causes brain fog. Celsius contains caffeine, which can prevent you from getting proper sleep if you consume it late in the day, and being sleep-deprived does result in cognitive issues like brain fog; however, sleep deprivation is not directly caused by Celsius or any energy drink. It depends on when you consume it so it's probably not the best idea to consume it before going to sleep.

Answer 4

Celcius causes brain fog

The article's main claim is that celsius and other caffeinated drinks link to brain fog. The article lists plenty of different health clinics and clinical journals that provide more information. Most of the articles that are listed are focused on specifics that are only semi-related to the claim. For example the Journal of Clinical Sleep Medicine is only focusing on how excessive caffeine late in the day leads to a lack of sleep. While this is true, it doesn’t help the claim that the overall article is making about brain fog because it never once mentions it. The article itself also states that brain fog is easily treatable, “Fatigue and brain fog should be easy to treat because they are likely related to your lifestyle. Changing your habits and routine can go a long way in giving you the energy you need to be your sharpest, most alert self who is ready to take on the day.” While what the overall article is saying is true it is definitely exaggerated for clicks. Caffeine can lead to restlessness and exhaustion, but it's the exhaustion and lack of sleep itself that can potentially lead to brain fog and other symptoms.

Answer 5

This claim is honestly miss leading i think we need to be able to differentiate people's feelings towards an experience they have had with something and scientific facts and data. I think it's important to check Caffeine tolerance levels Aswell as your hydration status before thinking you're suffering from brain fog caused by Celsius. Also check the sources you used NIh is a lot more reliable, aswell as the Mayo Clinic than other articles or sources of media you used. 

Meredith, Steven E et al. “Caffeine Use Disorder: A Comprehensive Review and Research Agenda.” Journal of caffeine research vol. 3,3 (2013): 114-130. doi:10.1089/jcr.2013.0016 

Answer 6

After examining this claim and fact checking with the source it provides, it seems to be only partially correct. The article describes the negative effect caffeine can have on cognition, as well as caffeine and coffee's impact on increasing brain fog. However, brands and energy drinks such as Celsius are never explicitly mentioned, meaning this claim is simply misleading.

Answer 7

After researching a bit on this topic, it seems that caffeine as a general topic seems to add to possible brain fog that can occur from tiredness. According to The Center for Functional Health, overstimulating your brain with caffeine can worsen the state of your health by increasing the likelihood of anxiety, depression, irritability, heart disease, etc. Though it can increase the effects of brain fog, caffeine and specifically Celsius may not be the root cause, so this claim is misleading.

Answer 8

This claim has been exaggerated. Articles write that drinking a caffeinated beverage, like Celsius, can cause brain fog when drunk after sleep deprivation. The article never calls out Celsius by name and does not explicitly say that energy drinks are worse for the body than other caffeinated drinks like coffee or tea. Many factors can contribute to brain fog. The amount and quality of sleep you get has a large impact on how your brain functions. This claim is misleading when it says that Celsius and other energy drinks can cause brain fog. However, those who consume them should understand the impacts that they have on the body.

Answer 9

This claim is oversimplified: caffeine does not directly lead to brain fog. This is an issue of correlation vs. causation. While there is evidence that prolonged caffeine intake throughout the day can decrease quality of sleep and lead to brain fog symptoms, there is no evidence that caffeine directly causes brain fog. One study showed that 35% of people with POTS syndrome (a condition characterized by repeating episodes of light-headedness, fatigue, and vertigo) reported feeling better after caffeine intake in a controlled experiment, while 33% reported feeling worse. This demonstrates the variability from person to person that goes with this claim. No, caffeine does not directly lead to brain fog for every individual, but prolonged intake throughout the day can affect sleep patterns and overall health.
