The article claims that Celcius causes brain fog. Celcius is a very popular energy drink right now, so the name in the title would lead many people to click on it. However, the article really means to talk about caffeine in general, citing a study on coffee. One study cited is from the Cleveland Clinic, which, when looking at the original article, is true. The second study is from the Journal of Clinical Sleep Medicine, which is also a true claim. Both of these sauces are reputable. The article itself has relatable sources to back its claims. Despite the slight clickbait of the title, the article successfully and correctly supports its claims.
