What caffeine does to your brain
- vonklaus 11y agoPutting a modal over the entire iphone screen is a great way to get me to hate your site. Article was decent, but mostly contained a semi-technical overview of well known info.
- mullingitover 11y agoMobile web browsing is a true nightmare on iOS. It's pretty shocking that it's taking Apple nine OS releases to address what's clearly a defect in their platform.
- deleted 11y ago[deleted]
- vonklaus 11y agomaybe the fault you find with Apple is not without merit, but surely you can't be suggesting that a websites choice of UI could possibly come down to apple.
- mullingitover 11y agoTaking away all control from the user in terms of how their device's browser is able to render websites is all on Apple. They could've fixed this a long time ago. I'm not a fan of Android at all, but I've been tempted to switch back purely because of the ability to run a spam filter in my browser.
- batou 11y agoIt this on windows phone too. It's not the phone's fault.
- electriclove 11y agoPretty useless article. Nothing new
- mjfl 11y agoMy father, who is a cardiologist, has all these stories about how they keep trying to prove that caffeine and coffee in general are bad for you, bad for your heart specifically. But the more they try to prove it is bad, the more they keep finding that caffeine is actually good for you and reduces the risk of heart disease. I'll have to ask him for specific studies. Now the sugar they put in the coffee, that's a different story...
- Frenchgeek 11y agoOn the other hand, it is very easy to prove that a lack of caffeine make me very bad for everyone else.
- pyre 11y ago> caffeine and coffee in general Why coffee specifically? Other things contain caffeine. Tea, for example.
- erkkie 11y agoTea also contains L-theanine which modulates the effects of caffeine: http://www.ncbi.nlm.nih.gov/pubmed/10737183 http://www.ncbi.nlm.nih.gov/pubmed/10737183
- provemewrong 11y agoTrue, but in miniscule amounts. Significantly lower than the doses taken by the people who use L-theanine as a supplement. Also L-theanine to caffeine ratio is all wrong. >Why pick pure l-theanine and caffeine over green or black tea? >Most studies done on the l-theanine-caffeine combination have a l-theanine to caffeine ratio that isn't consistent with ratios you would expect from most teas. The studies used about twice as much l-theanine as caffeine by weight. The ratio found in most teas is reversed, with the possible exception of high quality green tea.

- rubicon33 11y ago1. The modal made me consider instantly closing the site. If that article didn't REALLY interest me, I would have insta-closed it. 2. No offense, but this is pretty basic, high school biology class knowledge. Would be nice if we knew more than this in 2015.
- douche 11y agoAs I see caffeine validated, I wonder about other "upper" substances. I write code a lot better with a lip full of Skoal... And I'm sure there are other beneficial chemical compounds that have been given a black-eye. Certainly seems like there must have been something to all of the people I knew in college doing lines of adderall, who have probably upgraded to another white powder now that they work for Bridgewater...
- jarboot 11y agoVapes are starting to turn into that sort of thing since you can get juice with nicotine. The jury is still out on how bad it is for you, though.
- colechristensen 11y agoThe combination of nicotine and an MAOI is very much more addictive than nicotine alone – unknown substances in cigarette smoke mimic MAOIs. That is, many of the negative consequences of tobacco come from the delivery method instead of the desirable nicotine. That's not to say vaping doesn't have it's own (yet unknown) negative consequences. http://www.jneurosci.org/content/25/38/8593.full http://www.jneurosci.org/content/25/38/8593.full
- DanBC 11y ago> lip full of Skoal Tobacco in all forms has a justifiable black eye. We know that Skoal causes cancer of the mouth, throat, and pancreas. Chewing tobacco is better than smoking it, but it's still risky. People using chewing tobacco would be better off vaping which would give them the nicotine without all the other gunk.
- iopq 11y agoDifferent people have different caffeine metabolism. I can still feel it 12+ hours later.
- princeb 11y agoi am about 800-1600mg caffeine a day (almost all pill form since brewing and drinking coffee takes too much time) and i do not feel these so called muscle tremors, or abnormal heart rhythms.
- stared 11y agoDon't. One of my friends went up to 1.5g/day (using crystalline caffeine). After he had to give it up, he spend at least 6 months without energy, lethargic, sluggish, possibly depressed. After ceasing typical consumption brain goes back to normal in 1-2 weeks. But for huge doses it might be not the case. (BTW: If anyone knows more info on the length of caffeine withdrawal as a function of does, I would be grateful!)
- erkkie 11y agoYes! And you can test for it, I'm a mixed type myself so no coffee after 6pm: http://www.snpedia.com/index.php/Rs762551 http://www.snpedia.com/index.php/Rs762551
- walkingolof 11y agoI stopped drinking coffe 6 months ago and I feel that I raised my average productivity allot as a programmer, my day is more "even" in lack of a better word. I also sleep better, even if I didnt think I had an issue with that while drinking coffe.
- robmcm 11y agoI did the same, but found I was alert as much as with caffine, just unable to control when. For example I was far less productive in the mornings and after eating, and more alert in the evenings and when I wanted to sleep/relax.
- dsfsdfd 11y agoMe too, am naturally a night owl. I am most creative and productive 10pm - 3am. Without caffeine I'm a bit useless during the day - it lets me shift the time when I can be productive. It leaves me a bit dead in the evening though
- compostor42 11y agoSame. My average productivity is better and my sleep is much improved. Even if I only had one cup early in the morning, my sleep would still be disrupted. But unfortunately I have relapsed and am drinking a coffee right now...
- jmhain 11y agoI suspect that I would experience the same, if I could stop. I've tried at least a half dozen times in the last few years, but the withdrawal symptoms (headache and intense nausea) never seem to go away, even after several weeks without it. Unfortunately, I can't risk the decreased productivity longer than that.
- xorcist 11y agoI believe it likely that all drugs have a net negative effect in the long run. If humans in general had a chemical imbalance so our brains did not function optimally, and caffeine would fix that so that we just functioned better overall, shouldn't evolution have taken care of that by now? Messing with the signalling systems can be productive in the short run, and certain individuals have other needs, but it is unreasonable to assume it would be good for most people forever. I do drink coffee every day, because I like it, but I would never assume it makes me more alert or smarter in some way.
- leni536 11y ago> Scientists think that up to 400 milligrams of caffeine–the equivalent of roughly four cups of coffee–is probably safe for most healthy adults. Am I the only one who thinks this is a lot? I don't want to argue against this. When I was doing my bachelor's I pulled all nighters with one or two 500ml Monster energy drinks which is ~320mg max. Of course all nighters are not healthy but I was mostly worried about the caffeine intake.
- DanBC 11y agoI think it's a lot. It's scary to see how much caffeine people take.
- lwh 11y agoBut it's only one venti at Starbucks ;)
- leni536 11y agoI imagine 400mg is for daily intake. I don't now how it applies for the intake in one sitting. I had to look it up and Starbucks' venti Brewed Coffee really contains 415mg [1]. Seriously, this product looks dangerous. How come it's not regulated similarly as energy drinks? Maybe it's protected by "caffe culture", but I seriously doubt that drinking half a liter caffe was ever part of any culture.

- fasteo 11y agoI just found out a couple of weeks ago that a time-released caffeine formulation[1] works wonders for me. It gives me 8-10 solid of solid focus without all the jitter. This, plus my morning joe with coconut oil, that is. About 300mg total caffeine. [1] http://www.metrx.com/products/timed-release-caffeine/ http://www.metrx.com/products/timed-release-caffeine/
- provemewrong 11y agoWhat's the purpose of coconut oil?
- thecupisblue 11y agoI'm assuming he's talking about "Bulletproof" coffee, since Coconut oil contains medium chain triglycerides. Some claim it increases "clarity and alertness" and apparently boosts metabolism, lots of Paleo dieters use it. Never tried it personally, so can't attest for the benefits.
- fasteo 11y agoIt may sound odd, but Bulletproof coffee does not work for me at all; maybe the fatty acid profile of butter vs coconut oil are too different, but for me, coconut oil works and butter doesn't. Note that I have a primary mitochondrial defect, so my nutritional experiments results are always "weird", for the lack of a better word.
- fasteo 11y agoIt gives you energy very rapidly, as some of its fatty acids are sent directly from the digestive tract to the liver, that is, they do not require digestion. Much like fructose, but I have found that coconut oil gives me more energy than a fructose based breakfast. I usually don't eat a full meal from 22PM to 14PM (16 hours) and 15ml (one tablespoon) of coconut oil plus some almonds at noon are enough for me.
- jipumarino 11y agoIs it possible to approximate the amount of caffeine based on the beans weight I use for brewing? Before I take any further steps I'd like to know how close to the danger zone I am.
- Rudism 11y agoI suffer from occasional SVT episodes and gave up caffeine as a result (it causes them to trigger more frequently). I'm not sure how it would be in other industries, but as a software engineer, telling colleagues that I don't consume any caffeine at all is almost always met with looks of disbelief and horror. I never realized how dependent on it so many people around me are to get through their day until I gave it up.
