title_body: Sweating due to coffee intake
upvoted_answer: Coffee can cause some sweating when consumed in very high dosages. Your core temperature increases because of central nervous system activation and your body tries to regulate temperature. However 5 cups a day don't seem close to an overdose unless your caffeine tolerance is very low and studies have shown that normal dosages of caffeine intake don't alter core temperature or increase sweating to an extent where it would affect your hydration (see e.g. McLellan et. al 2016 for a Review). It still might be noticeable if you sweat a lot in general. I would just trial and error it by not drinking coffee for a few days. You might notice increased sweating for a day or two from withdrawal but that should pass after a couple of days. However these "health" websites have a lot of misinformation on them that are not scientifically supported.
