Caffeine dependence

Caffeine is a common central nervous system stimulant naturally occurring as part of coffee, tea, associates and other plants. It is also an additive as a beverage for many consumer products, especially energy drink advertisements. Caffeine is also added to soda water such as Coca Cola and Pepsi. Pure caffeine powder has a bitter taste, so it is specified as a fragrance in the ingredient list.

The mechanism of action of caffeine is slightly different from cocaine and substituted amphetamine, and caffeine blocks adenosine receptor A and A2A. [1] Adenosine is a byproduct of cellular activity and stimulation of adenosine receptors causes fatigue and sleep. The ability of caffeine to block these receptors means that levels of dopamine and norepinephrine, the body 's natural stimulant, will continue to maintain high levels.

The diagnosis manual of mental disorders explains four diseases related to caffeine, such as addiction, withdrawal symptoms, anxiety, sleep, etc. [2]

Overdose of caffeine may cause mild physical dependence. [3] Humans are not documenting caffeine poisoning, or the form of morbid and compulsory use. [3]

People who consume at least 100 mg of caffeine (caffeine contained in a cup of coffee) a day acquire physical dependence which can cause withdrawal symptoms such as headaches, muscle pain, stiffness, lethargy, nausea, vomiting etc Can show you that you are feeling bad and obviously irritated. Professor Roland Griffith, professor of neurology at Johns Hopkins University in Baltimore, strongly believes that caffeine withdrawal should be classified as a psychological disorder. [4] His research showed that smoking began within 12 to 24 hours after stopping caffeine intake. And it may last until the 9th. [5] Continued exposure to caffeine causes the body to produce more adenosine receptors in the central nervous system and therefore becomes more sensitive to the effects of adenosine in two ways. First, it reduces the stimulatory effect of caffeine by enhancing tolerance. Second, if caffeine stops taking intake, the effect of the body on adenosine becomes more sensitive, so that caffeine's withdrawal symptoms increase. Caffeine tolerance developed rapidly. 7 days after ingesting 400 mg of caffeine three times a day, caffeine tolerance to sleep disturbance was observed, 300 mg was taken three times a day for 18 days, and complete tolerance was observed. [6]

In fact, more clinical, epidemiological and genetic research of caffeine addiction is urgent. To date, national population studies have not been undertaken to investigate the prevalence and severity of caffeine dependence in the general population, and most studies have shown that caffeine dependence features in general populations and special populations are relatively It depends on small sample size. However, recent reports indicate that caffeine dependence can lead to clinically significant pain and dysfunction, and many people are unlikely to seek caffeine dependent treatment for them It is painful. Because of this new evidence, caffeine use impairment is now recognized as a condition for further study by DSM - 5.

There are several reasons for this depending on what you mean by 'addiction'. Caffeine is a stimulant of the central nervous system, frequent use of caffeine can cause mild physical dependence. But caffeine does not threaten your social or economic health like your body, addictive medicine. (Although you may not agree after seeing you spend every month at a coffee shop!) Your body absorbs caffeine quickly. But it also removed it soon. Through the treatment of the liver mainly, caffeine has a relatively short half life. This means that it takes an average of 5 to 7 hours to get rid of your body half. After 8 to 10 hours, 75% of the caffeine has disappeared. For most people, drinking one or two cups of coffee in the morning will not affect night's sleep.

Coffee For professional coffee drinks from regular coffee, black coffee, or your favorite shop, you will consume 50 to 500 mg of caffeine, depending on the number of ounces you drink. If you are trying to limit the intake of caffeine, you can choose to remove caffeine, but caffeine-free cups also contain a small amount of caffeine. "Energy drinks are potentially dangerous to people suffering from heart disease because they contain such high caffeine content in small amounts.In addition, children and young people should not drink energy drinks," Brown said, Said
