What are the risks of drinking coffee regularly?

For many people, a morning cup of refreshing coffee has become a habit. But new research suggests that drinking coffee doesn't necessarily lift your spirits-it may actually make you less productive.

Every day, millions of people, from drivers working the night shift to college students cramming late at night, turn to pick-me-ups like coffee to keep themselves awake, clear and productive.

Substances we normally think of as pick-me-ups-coffee and amphetamines, for example--aren't guaranteed to boost your motivation.

Hoskins studied the counter-effects of refreshing substances by making rats walk through a maze. As with humans, mouse populations include both industrious and lazy members. For the lazy mice, coffee and amphetamines made them more active, trying harder to find the exit from the maze. For the hardworking mice, coffee and amphetamine made them more inactive.

Although the above research may be a little discouraging, experts drink coffee and say: "coffee can be a miracle life-saving drug." When was the last time you heard a doctor say "magic"?

A large number of epidemiological studies have confirmed that coffee has the following magical effects:

Drinking more than three cups of coffee a day can reduce a woman's risk of skin cancer by 20%.

Drinking more than six cups of coffee a day can reduce a man's risk of prostate cancer by 60%.

A cup of coffee a day can reduce a woman's risk of stroke by 25%.

Two cups of coffee a day can reduce a woman's risk of depression by 20%.

"Black coffee is best, with at most a little skim milk added to reduce calories." Experts suggest that decaf coffee is not as effective as black coffee, so if you can stand it, it is best to drink black coffee.
