Caffeine is the
most used drug in the world. Caffeine is used to fuel the human
body, making people feel more awake and energetic. This addictive
drug was discovered in 1819 by a man named Friedlieb Runge.
Friedlieb found this substance while examining mocha beans.
Caffeine can make people more awake, alert, and able to concentrate. Throughout the day, a chemical called adenosine builds up in the human body. The nervous system has special receptors to monitor adenosine levels. As the day goes on, more and more adenosine passes the receptors making people sleepy. When consuming caffeine, the receptors bind together, stopping the adenosine from passing the receptors. This process leaves people feeling more awake and focused (Caffeine Informer show more content

When a pregnant woman drinks coffee, the caffeine crosses the placenta into the amniotic fluid and into the baby's bloodstream. While the woman's body goes to work and starts metabolizing and getting rid of that caffeine, the baby's body is still developing and takes a much longer time to process the caffeine. As a result the baby is exposed to all the effects of caffeine much longer than pregnant woman. Women that are pregnant are recommended to consume no more than 200 mg of caffeine daily. (SITE)
