However, children can die from as little as 1 gram of caffeine.

Caffeine improves our focus and ability to concentrate, which surely enhances linear and abstract thinking, but creativity works very differently. It may depend on the loss of a certain kind of focus, and the freedom to let the mind off the leash of linear thought.

Cognitive psychologists sometimes talk in terms of two distinct types of consciousness: spotlight consciousness, which illuminates a single focal point of attention, making it very good for reasoning, and lantern consciousness, in which attention is less focused yet illuminates a broader field of attention. Young children tend to exhibit lantern consciousness; so do many people on psychedelics. This more diffuse form of attention lends itself to mind wandering, free association, and the making of novel connections — all of which can nourish creativity.

This, more than anything else, is what made caffeine the perfect drug not only for the age of reason and the Enlightenment, but for the rise of capitalism, too. The power of caffeine to keep us awake and alert, to stem the natural tide of exhaustion, freed us from the circadian rhythms of our biology and so, along with the advent of artificial light, opened the frontier of night to the possibilities of work.

What coffee did for clerks and intellectuals, tea would soon do for the English working class. Indeed, it was tea from the East Indies — heavily sweetened with sugar from the West Indies — that fuelled the Industrial Revolution. We think of England as a tea culture, but coffee, initially the cheaper beverage by far, dominated at first. A beverage that only the well-to-do could afford to drink in was by consumed by virtually everyone, from the society matron to the factory worker.

To supply this demand required an imperialist enterprise of enormous scale and brutality, especially after the British decided it would be more profitable to turn India, its colony , into a tea producer, than to buy tea from the Chinese. This required first stealing the secrets of tea production from the Chinese a mission accomplished by the renowned Scots botanist and plant explorer Robert Fortune , disguised as a mandarin ; seizing land from peasant farmers in Assam where tea grew wild , and then forcing the farmers into servitude , picking tea leaves from dawn to dusk.

The introduction of tea to the west was all about exploitation — the extraction of surplus value from labour, not only in its production in India, but in its consumption by the British as well. Tea allowed the British working class to endure long shifts, brutal working conditions and more or less constant hunger; the caffeine helped quiet the hunger pangs, and the sugar in it became a crucial source of calories. From a strictly nutritional standpoint, workers would have been better off sticking with beer.

The caffeine in tea helped create a new kind of worker, one better adapted to the rule of the machine. It is difficult to imagine an Industrial Revolution without it.

S o how exactly does coffee, and caffeine more generally, make us more energetic, efficient and faster? How could this little molecule possibly supply the human body energy without calories? Could caffeine be the proverbial free lunch, or do we pay a price for the mental and physical energy — the alertness, focus and stamina — that caffeine gives us?

Alas, there is no free lunch. It turns out that caffeine only appears to give us energy. Caffeine works by blocking the action of adenosine, a molecule that gradually accumulates in the brain over the course of the day, preparing the body to rest.

Caffeine molecules interfere with this process, keeping adenosine from doing its job — and keeping us feeling alert. So the energy that caffeine gives us is borrowed, in effect, and eventually the debt must be paid back.

For as long as people have been drinking coffee and tea, medical authorities have warned about the dangers of caffeine. But until now, caffeine has been cleared of the most serious charges against it. Though high doses can produce nervousness and anxiety, and rates of suicide climb among those who drink eight or more cups a day.

My review of the medical literature on coffee and tea made me wonder if my abstention might be compromising not only my mental function but my physical health, as well. However, that was before I spoke to Matt Walker. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. Select basic ads.

Caffeine addiction is the excessive and harmful use of caffeine over a period of time, such that it has negative effects on your health, social interactions, or other areas of your life. To be clear, caffeine has been associated with many positive side effects. Research has connected this plant-derived stimulant to improved mood , relief from headaches , and perhaps a reduced risk of other major medical issues such as strokes , Parkinson's, and Alzheimer's.

Yet, some people experience negative issues as a result of their caffeine use or have difficulty coping without caffeine. Though rare, there have even been cases of caffeine overdose. Caffeine is the most widely used drug worldwide. In the United States, coffee and soda are the top caffeine sources, whereas African and Asian countries tend to consume it in soda and tea.

When caffeine turns problematic is when it disrupts your life in a negative way, yet you're unable to stop consuming it. Or you consume it in amounts that are potentially dangerous to your health despite knowing that it may be harming you mentally or physically. Although caffeine addiction is not a formally recognized condition in the " Diagnostic and Statistical Manual of Mental Disorders DSM-5 ," a manual used by clinicians to classify and diagnose mental health concerns, the publication does mention a few caffeine-related issues, such as intoxication and withdrawal.

Caffeine intoxication, caffeine withdrawal, caffeine-induced anxiety disorder, and caffeine-induced sleep disorder are all recognized in the "DSM-5," and caffeine use disorder has been identified as requiring further study. Caffeine has various effects on the body that are potentially harmful to your health. There have been associations of caffeine with increased blood pressure and heart rhythm changes. There is also a question of whether caffeine might be associated with increasing your risk of osteoporosis.

One study found this to be the case for women in menopause with high caffeine intakes. Caffeine can also decrease your health by disturbing your sleep if it is consumed within six hours of bedtime. Sleep is also when your body heals, making it important for total health and even for immune function.

As caffeine is a stimulant, consuming too much can cause a cluster of symptoms associated with stimulation of the brain and nervous system. As with all addictions, the pleasurable effects of caffeine can also sometimes mask other issues.
