The answerto this is "All things in moderation". Coffee and tea have been shown to be high in anti-oxidants (these prevent "free radical damage to cells). Caffeine has also been shown to increase concentration and reaction times and to increase test scores for young adults who have a cup of coffee immediately prior to an exam. it has also been shown to be effective in treating and peventing migraine headaches when combined with aspirin or ibuprofen. The downside is that too much caffeine can cause "the jitters" - racing heartbeat, thready pulse, excitabiity, irritability. Caffeine is and should be treated as, an over the counter pharmaceutical. Use a cup of coffe as you might an aspirin - when you need a pick me up and in moderation

Too much caffeine can cause restlessness, anxiety, irritability, sleeplessness, headaches, nauseas, muscle tremors and even abnormal heart rhythms. So yes, caffeine can be dangerous in high doses. So what is considered high?
According to the Mayo foundation, most people can ingest between 200 and 300 milligrams a day with no problems. To put it in perspective, one eight ounce cup of coffee is generally 135 milligrams of caffeine.

Higher doses of caffeine can cause anxiety, dizziness, headaches, and the jitters and can interfere with normal sleep. Very high doses of caffeine - if you were to drink many cups of coffee in a day or take a box of No-Doz™ - would be harmful to the body. Caffeine is addictive and may cause withdrawal symptoms - such as severe headaches, muscle aches, temporary depression, and irritability - for those who abruptly stop consuming it....The amount of caffeine needed to affect each person differs. Caffeine sensitivity refers to the amount of caffeine that will produce an effect in someone. This amount varies from person to person."

With some medical conditions, such as gastroesophageal reflux disease, a person's body may be so sensitive that doctors advise: "Don't drink coffee or sodas that have caffeine in them," and "Don't eat foods or drink

Even in those without such conditions, "Caffeine exhibits a number of biological effects resulting from its diuretic and stimulant properties. Research has shown that some sensitive individuals experience side effects such as insomnia, headaches, irritability and nervousness. As with any substance, there can be numerous other contributing factors, but Canada's Guidelines to Healthy Eating advises consumers that limiting caffeine is a wise precaution."
