Celsius causes brain fog

Question

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

Comments

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.

I agree with the claim to some extent, but I believe the credibility of the article would be significantly enhanced if there were more resources and detailed information specifically about the Celsius drink itself. Providing direct references, studies, or expert opinions related to the product would help strengthen the argument and make it more trustworthy. Additionally, if the claim were framed differently maybe focusing on other aspects or backing up the statement with more concrete evidence the article would appear more credible overall.

Answer 1

Fact Check 4; 

Too much caffeine can create problems like lack of sleep, poor diet, or stress but I don’t believe it is the main factor in brain fog. This claim states a direct brand which does not apply to all. Caffeine can boost energy for a short time but those who experience brain fog or fatigue should check their overall health. There are no studies that directly show the effects of caffeine being brain fog or fatigue but it is recommended to adjust intake if they are having a negative experience.

Answer 2

This article discusses the potential of Celcius causing brain fog for the consumers. After doing a bit of research on this topic, I would say that although caffeinated inated drinks have caused brain fog, I dont think its right to solo out Celcius. Studies show that caffeine can interfere with sleep patterns which causes worse sleep which ends up being one of the leading causes of brain fog. So drinking a Celcius could very well make someone have brain fog, but the reason is due to its caffeine. The argument I am making is that the title solos out a company of energy drinks making them seem as if only their product has these effects but in reality you could drink a coffee and have the exact same "brain fog" that you do for Celcius. All in all I personally think that although there is some truth to this article, I don’t think it is entirely factual and instead misleading.

The heading and article claim that there is a direct correlation between caffeinated drinks and brain fog and how caffeine worsens fatigue by disturbing sleep patterns, especially when taken later in the day. 

The article cites sources such as Vail Health and the Clevland Clinic to support its claim, though the evidence he provides can be slightly misleading and exaggerated making it seem like caffeine is the leading cause of brain fog when in reality it is not. An example is when the author states that "brain fog is often linked to chronic fatigue syndrome (CFS)" and that people turn to caffeine for an easy remedy proving that there is not a direct correlation. Also  He mentions how "caffeine can have a negative effect on people's sleeping patterns, according to the Cleaveland Clinic, which notes that those with caffeine sensitivities can also have insomnia and feelings of restlessness." Although this is true, this fails to address the fact that there are many people who have built a tolerance to caffeine and its effects and can consume it daily without any negative effects according to Harvard Health. He also doesn't highlight enough how brain fog is more so caused by other factors like poor dieting, stress, health conditions, hydration, etc. 

I believe that the headline was meant to catch the reader's attention without making the title too long. However, in the process, he oversimplifies the connection between brain fog and caffeine. While he is right that caffeine can lead to sleep disturbances, caffeine is not the direct cause of brain fog.

Answer 4

The claim Celsius and other caffeinated drinks can lead to brain fog and fatigue is not directly true and can be misleading. In the article you linked it discussed what brain fog is, brain fog treatment, the affects caffine can have on you, and how brain fog can be inadvertantly caused by the use of caffine. Towards the end of the article they claim that if a person took 400mgs of caffine 6 hours before bed, it could cause the person to loose up to a hour of sleep a night in turn a person could "quickly become sleep deprived". While its true "400 mg of caffeine can reduce sleep by 1 hour" according to the ​Journal of Clinical Sleep Medicine​, that doesnt connect caffine to brain fog; caffine can cause a lack of sleep if used improperly. Leading to sleep deprivation, which in some cases might be connected to brain fog. So the claim that caffeinated drinks cause brain fog is wildly exagerated do to not only the fact most caffeinated drink dont have 400 mg of caffine, but also it would be the sleep deprivation would cause you to have this "brain fog" the drink.

The article entitled "The Consumption of Energy Drinks Induces Blood-Brain Barrier Dysfunction in Wild-Type Mice" by Frontiers in Nutrition discusses the impact of energy drinks, including caffeine, on brain health. It deals with the impacts such beverages can have on the blood-brain barrier-a very vital component of brain protection-and introduces the risk of dysfunction when one consumes too much of these energy drinks. This research helps reinforce the view of caffeine affecting brains negatively and can support my supposition that something like a Celsius drink might develop brain fog or fatigue in subjects. Though focusing on the aspect of physiological variations in mice alone, this evidence is overwhelming: the fact that energy drink consumption containing caffeine, just like Celsius energy, may actually influence cognitive incapacitation. This therefore corroborates my assertion that energy drinks, through caffeine and other additives, may bring about mental fatigue and fogging of the brain.

Answer 6

The article used for the claim, Celsius Causes Brain Fog, goes over topics on how caffeinated drinks can lead to brain fog and fatigue. 

The article, Caffeine & Brain Fog, starts by providing information on what brain fog is and what kind of correlation it may have with caffeine. Our author refers to brain fog “as hazy, unclear state of mind” and is most likely linked to chronic fatigue syndrome (CFS), which is fatigue that interferes with daily activities, which is said to affect about 1 million Americans. This is important because the author ties brain fog to caffeine and how the effects of caffeine affect how we feel throughout the day. Caffeinated drinks, such as coffee, are very quickly absorbed and distributed throughout your body, including to your brain. It's here that caffeine elicits its most classic effect — helping keep you alert and awake.” However, this may harm your sleeping schedule and ultimately lead to CFS and brain fog. 

Additionally, this doesn't prove that Celsius or caffeinated drinks cause brain fog. In the article it says that “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.” Indeed, caffeine could potentially lead to CFS due to its nature to keep you awake and ruin sleeping patterns and other healthy habits. However, the claim created a narrative that Celsius was the direct cause of brain fog, yet the brand was never included in the article. This clickbait headline provided no information on the side effects of Celsius or studies proving that Celsius has directly caused brain fog in the past. Although Celsius indeed contains caffeine, which is a substance that could potentially lead to brain fog, it is not the direct cause of brain fog. Instead, CFS and brain fog are the direct effects of unhealthy lifestyles and poor sleeping habits.

Answer 7

The claim the author of this post made is slightly misleading but based on this article and others the claim is mostly correct. The article this author linked was very factual and was backed up with a lot of evidence and links to those articles where they got their facts from. Linked articles ranging from research studies of trusted scientists to .gov websites. The article argues that caffeine causes brain fog for multiple reasons. First, caffeine affects your sleep for upwards of 6 hours until it exits your bloodstream. Also, it is argued that once you intake caffeine it causes an extra hour of restless tossing and turning of your bed before you actually fall asleep. This causes an irregular sleep schedule causing poor quality sleep which leads to brain fog.

For the most part, this claim is factual showing a lot of evidence of how caffeine affects your sleep causing brain fog but it is slightly misleading. For instance, the argument that caffeine causes brain fog is clickbait. A more accurate title should be on how the effects of caffeine on your sleep are what causes brain fog and not that if you consume caffeine it will give you brain fog. Also, the claim of the post itself is misleading, it states that specifically Celsius gives you brain fog but after doing more of a deep dive I realize that caffeine intake can cause you brain fog. Nowhere in the article does it prove that Celsius gives you brain fog which makes this post misleading. Since Celsius is an energy drink it is possible that the effects of the drink can cause brain fog but it would be more accurate if they provided a post that talks specifically about Celsius and not caffeine especially because Celsius is branded as a healthier caffeine beverage promoting metabolism and marketed towards athletes.

Answer 8

While some people may experience brain fog with the energy drink Celsius, there is not enough evidence to suggest that Celsius specifically causes brain fog. 

Brain fog is used to describe symptoms causing cognitive impairment, where your ability to think clearly and focus is affected. When reading an article about the neurological effects of caffeine, it was found that caffeine typically enhances alertness, increases arousal of the brain, decreases fatigue, and improved reaction times.

However, I cannot say this claim is false because there is evidence that caffeine can cause impaired learning and memory, anxiety, overstimulation, and increased cortisol secretion, which could be what leads people to feel "brain fog".

An important thing to consider is that "brain fog" is not a medical condition, so saying that a stimulant causes this group of symptoms cannot be confirmed without scientific boundaries for what classifies "brain fog". Also, I could not find any source connecting the Celsius brand specifically to brain fog, just caffeine. This leads me to believe that this claim can be misleading, but can't be confirmed true or false.

Answer 9

the main claim of this article is that caffeine causes "brain fog" or clouds cognitive clarity. the article suggests that caffeine is commonly used to enhance alertness or is used to make you feel more awake, but that in excess it can actually do the opposite. the article references the cleveland clinic, which is a reputable institution and supports its claims about caffines effect on sleep and brain function. the evidence is reliable as it is drawn from an established medical research organization. if any of the claims in the articles were to be false, the intention behind it may be to warn people of potential negative effects of the overconsumption of caffeine.

Answer 10

I find this claim to be somewhat exaggerated as the article "Caffeine and Brain Fog" strongly supports the claim that caffeine can cause brain fog and fatigue, but mainly only when consumed in large amounts and or close to bedtime. 

Another article called "Are Energy Drinks Bad for You?" Discusses how caffeine can boost alertness and concentration in moderation, but only when consumed in access can caffeine lead to feelings of anxiety and decreased mental clarity. Most articles surrounding the concept of caffeine and brain fog do not specifically state that Celsius and or specific energy drinks are the root cause. Instead, most evidence-based articles claim that only in excessive amounts there are negative effects.
