For many people, a cup of refreshing coffee in the morning has become a habit. But new research has found that drinking coffee is not necessarily refreshing, but may make you less productive.

From night shift drivers to late-night recitation college students, millions of people every day use refreshing substances, such as coffee, to keep themselves awake, think clearly and improve their work efficiency.

Substances that we usually think of as refreshing-- such as coffee and amphetamines-- are hardly guaranteed to boost your motivation to work.

Hosking studied the countereffects of refreshing substances by making mice walk through a maze. Like humans, there are hardworking and lazy members in the mouse community. For lazy mice, coffee and amphetamines make them more active and work harder to find maze exits. For hardworking mice, coffee and amphetamines make them lazier.

Although the above research may make people feel a little discouraged, experts said over coffee: "Coffee can be called a magical life-saving drug." Think about it, 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 women's risk of skin cancer by 20%.

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

A cup of coffee a day can effectively 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 the best, and you can only add a little more skim milk to reduce calories." Experts suggest that low-calorie coffee is not as effective as black coffee, so if you can bear it, it's best to drink black coffee.
