How does caffeine affect the body?

Caffeine is a nervous system stimulant and the most common effects of consumption in humans are increased wakefulness and restored alertness. Its stimulant affect also helps improve body coordination and clearer thinking. In high does caffeine can have the opposite affect and actually impair body coordination and movement. These effects of caffeine begin less than an hour after consumption and wear off after about five hours. Caffeine may also increase the frequency of urination, but many caffeine uses acquire immunity to this symptom.

Consuming large amount of caffeine can cause caffeine addiction or caffeinism. People who have this addiction may feel irritable, restless, nervous, and experience headaches or heart palpitations; particularly if they cut back or do not have any caffeine. Other conditions associated with caffeine consumption are caffeine intoxication, caffeine-induced sleep disorder, and caffeine-induced anxiety disorder. Caffeine can cause sleep problems in some people by disturbing their sleep patterns and leading to insomnia. A caffeine induced sleep disorder is a disruption in sleep patterns that warrants clinical care and treatment. Small doses of caffeine are said to have little or mild positive effects on anxiety. High doses have been linked with a marked increase in anxiety causing caffeine-induced anxiety disorder. Withdrawal from caffeine can also cause anxiety problems.
