Health and Coffee

Caffeine stimulates the central nervous system in a manner that causes a short term elevation of blood pressure, an increased metabolic rate and increased blood flow to the muscles.

What this produces in terms of the sensation and experience of consuming caffeine for most people is a variety of physical and psychological effects. These include enhanced mental alertness, an increased ability to concentrate, swift reaction times and prolonged vigilance for performing tasks.

Coffee also seems to be a mood elevator for most people and even has been linked to a reduced risk for depression amongst regular coffee drinkers. Coffee also impacts physical as well as mental endurance, which is why it can be used to enhance athletic performance.

Moderate caffeine consumption has almost always been found to be free from adverse effects and research conducted over the last ten to twenty years has in fact established some beneficial effects.
