The first is that it improves alertness and enhances concentration of the drinker. Caffeine increase rapid information processing by almost 10 %. It has proven to greatly effect performance in timed reaction studies. This can be used favorably in almost any situations, but is primarily wanted during late evening hours to early morning hours. This is a reason why caffeine consumption is, on average, greater in those who stay awake to late hours of the night for their occupation, education, recreation or other reasons. Some caffeine research has also identified athletic physical performance being enhanced by the use of caffeine. Studies in the UK have found that caffeine users, mainly coffee drinkers, have greater performance levels that do not decline as long as caffeine intake is steady. Coffee consumption has also been proven to reduce car accidents. It is encouraged for tired drivers to take a thirty minute break during the course of driving long distances, especially during the evening hours; during this break the driver should drink two caffeinated coffees (150mgs of caffeine) and possibly take a short rest.

If you do not consume the average caffeine that your body has been dependent on, some withdrawal symptoms may include extreme headaches for days, crankiness, tiredness and, in extreme cases, nausea and vomiting. This withdrawal will only occur with about half of caffeine users, but those who do not find these withdrawal symptoms may find problems when returning to caffeine use. These problems may include headaches as well.. As the intake is greater other side effects may arise. Some of these other effects may make the drinker jittery and unable to sleep correctly. Apart from being highly addictive and causing unpleasant withdrawal symptoms if we stop drinking it suddenly, research shows that even a little bit of coffee may reduce fertility by damaging sperm.
