When the early sixteenth century entered the coffee to pharmacies and cafes in Europe, where stunned consumers ability to alert the brain, was considered coffee at the beginning of their entry as a powerful and dangerous, and was calls at that time to ban their use, and turned intact today as used coffee to millions around thethe world, although it is still classified as a drug, it can not be denied effects that are similar to the effects of the medication.
Scientific research has shown that coffee with caffeine, which is classified as a stimulant, where suppresses chemicals in the brain rather than liberate, because of the similarity of chemical caffeine with a substance in the brain called adenosine secreted nerve endings to curb activity of brain cells, when eating a cup of coffee, the substance Caffeine takes site adenosine, which prevents adenosine from inhibiting activity of brain cells, which puts it in a state of activity and excitement, according to studies, the amount of caffeine in two cups of coffee enough to overcome the receptors adenosine in the brain for two hours, so it's to Avid in alert and activity of the body when increase intake coffee, studies have shown that low doses of caffeine can improve mental performance, as demonstrated by a study conducted by psychologist "Harris Lieberman" in the Research Institute of the U.S. Army, that doses of caffeine are even small doses, led to enhance the performance of human , where alerted their brains to the speed of thought and interaction faster and more focus and thereby improving performance. The optimal dose is 100-200 mg almost of caffeine, which is the amount found in a cup of coffee capacity five ounces, and preferably a cup of coffee in the morning, and a cup of late afternoon when the effectiveness of caffeine have vanished and diminished activity, has researchers noted that eating more caffeine does not promotes greater actual performance. While large doses of coffee (more than five cups a day), can cause anxiety and restlessness and even Parkinson (This limit may be described as poisoning coffee), and because people differ in the extent affected by coffee, the dose of caffeine may be ecstasy to someone while you are Sama to others.
But strange that coffee houses are and soothing at the other, the Harvard study revealed amazing issue is that coffee causes sleepiness, rather than activity in some people, and are believed to be suffering from a rare condition and contradictory overcome them sleepy when drinking coffee.

The Coffee property psychologist effect, used widely throughout the world, and has an active role in improving mood and resistance feel unhappy and improvement ăŇÇĚí after eating in the morning or the afternoon and evening, and have an effect in modifying the mood and perhaps chronic depression, so some argue that a cup of coffee Morning brings a smile and this statement too seldom true. And coffee causes a sense of euphoria, happiness and sense of satisfaction and relieve anxiety, and supported by Dr. (Melvin Konner / Emory University) use a mild caffeine as an antidote to depression. The lead coffee some in anxiety, nervousness, tension, and the infection is concerned with chronic, and may increase the fear and the fear and suspicion, with attacks of rapid heartbeat and sweating and trembling, and although the caffeine found in coffee doses normal safe for most people, it improves mood and performance, but there is a group of those who are brain cells they are sensitive to caffeine, drinking five to six cups a day, can lead to mental illness. The more dose coffee led to affect the increase concern for the sensitivity of caffeine, and classified Psychological Association American poisoning Balkavin mental disorder includes excitement and restlessness and rapid heartbeat, insomnia and agitation psychomotor and floundering thinking and speech, and the problem lies in the lack of distinction between poisoning symptoms coffee and symptoms of anxiety neurosis .
Back the difference in the effect of coffee on humans to the different nature of the human body, reportedly done in vulnerability caffeine, some have high sensitivity to the impact of anxiety and anguish when caffeine as exceeding their reactions standards expected, and up to provoke excessive and panic, and surprisingly they hit some healthy wheneating four to five cups of coffee. It is clear that the reaction and sensitivity affected brain differs among humans in their sensitivity to caffeine, is to stop drinking coffee (caffeine) is the fastest and best treatment for anxiety, says Dr. Malcolm Bruce of the Institute of Psychiatry in London, said the study demonstrated that 25% of his patients disorder anxiety achieved healing exciting after they stop drinking coffee.
Therefore, we find that the coffee had a positive impact of improved mood and activity for some people, but it may lead to laziness and sleep with others, while it may affect others concerned and bouts of fear and panic and heart palpitations, and depending on the status of biological and genetic in person, it is important to distinguish that eating food or medication may help some people, while others may for اينفع others and may have hurt them and hurt them.
