Coffee drinking is addictive, or it's a habit you can't get rid of, and sometimes drinking too much coffee can have a certain impact on your mood, which may make you nervous and upset. However, the role of coffee on the human body can not be ignored, whether in the spirit or physical function, caffeine can play a good role. Here are eight of caffeine's main effects:

1. Memory: 200 milligrams of caffeine (about the caffeine content of two 8-ounce cups of coffee) can prolong memory, according to recent studies of poor conditioning.

2. Mood: women who drink four eight-ounce cups of coffee a day have a 20 percent lower risk of depression than those who don't, according to a study by the harvard school of public health. This is because caffeine has an effect on brain chemicals such as serotonin and dopamine.

3. Skin: Women who drink more than three cups of coffee a day have a significantly lower risk of developing basal cell carcinoma, according to a 2012 study.

4. Heart: Consuming 200-300 mg of caffeine per day can help improve blood flow and thus make the heart work better.

5. Liver: Drinking more than two cups of coffee a day is associated with a significant reduction in liver disease such as cirrhosis.

6. Energy: Drinking 3-4 cups of coffee an hour before exercise can prolong exercise, according to the Public Library of Science.

7. Legs: Men who drank six cups of coffee a day reduced their risk of gout by 59 percent because coffee may lower uric acid levels in the blood.

8. Diabetes risk: drinking eight eight-ounce cups of coffee a day reduces the risk of type 2 diabetes by 33 percent, according to a review of 28 harvard studies.
