Caffeine is a bitter substance found in coffee, tea, soft drinks, chocolate, some nuts and certain medicines. It has many effects on the body's metabolism, including stimulating the central nervous system. This can make you more alert and give you a boost of energy.

For most people, the amount of caffeine in two to four cups of coffee a day is not harmful. However, too much caffeine can make you restless, anxious and irritable. It may also keep you from sleeping well and cause headaches, abnormal heart rhythms or other problems. If you stop using caffeine, you could get withdrawal symptoms.

Some people are more sensitive to the effects of caffeine than others. They should limit their use of caffeine. So should pregnant and nursing women. Certain drugs and supplements may interact with caffeine. If you have questions about whether caffeine is safe for you, talk with your health care provider.

Cocaine disrupts woman's estrus cycle, may explain sex differences in cocaine addiction

Cocaine disrupts woman's estrus cycle, may explain sex differences in cocaine addiction

Women are more sensitive to the effects of cocaine and more susceptible to cocaine abuse than men. Cocaine's ability to disrupt a woman's estrus cycle may explain the sex differences in cocaine addiction, and new evidence that caffeine may be neuroprotective and able to block cocaine's direct effects on the estrus cycle reveals novel treatment possibilities, according to an article published in Journal of Caffeine Research: The International Multidisciplinary Journal of Caffeine Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Drug-loaded plaster delivers active agent to premature babies via membrane

Drug-loaded plaster delivers active agent to premature babies via membrane

The development of minimally and even non-invasive technologies is increasing in the medical field. It is now possible, for instance, to carry out a range of operative procedures using keyhole surgery with minimal use of the scalpel, leaving only tiny scars as a result. Similar opportunities are now becoming available when providing doses of active agents to patients – instead of using injections or probes to deliver drugs, it will in future be possible to supply them via a plaster which continuously, gently and painlessly delivers the required dosage through the skin.

Decaffeinated coffee may benefit liver health

Decaffeinated coffee may benefit liver health

Researchers from the National Cancer Institute report that decaffeinated coffee drinking may benefit liver health. Results of the study published in Hepatology, a journal of the American Association for the Study of Liver Diseases, show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help protect the liver. [More]

A new, large-scale study has identified six new genetic variants associated with habitual coffee drinking. The genome-wide meta-analysis, led by Harvard School of Public Health and Brigham and Women's Hospital researchers, helps explain why a given amount of coffee or caffeine has different effects on different people and provides a genetic basis for future research exploring the links between coffee and health.
