Gavin Pereira, a professor of epidemiology and biostatistics at Curtin University in Australia. It’s not clear whether this study effectively shows causation between maternal caffeine consumption and child height, according to Dr. And even chocolate has about 31 milligrams of caffeine.īut the differences found in the most recent study were found even in the children of parents who drank less than half a cup of coffee per day while pregnant - well below the current guidelines, Gleason said. Some experts disagreeįor context, a mug of caffeinated tea typically has about 75 milligrams of caffeine, a mug of instant coffee has about 100 milligrams and a mug of filtered coffee has about 140 milligrams, according to the Cleveland Clinic.

The American College of Obstetricians and Gynecologists currently recommends limiting caffeine consumption to less than 200 milligrams per day while pregnant. “To be clear, these are not huge differences in height, but there are these small differences in height among the children of people who consumed caffeine during pregnancy,” said Gleason, who is a research fellow at Eunice Kennedy Shriver National Institute of Child Health and Human Development.
Jessica Gleason, a perinatal epidemiologist. If you stick to less than four cups per day – and are otherwise healthy – caffeine is one of the safest and most beneficial psychoactive drugs you can take.Starting the day with a hot cup of caffeinated coffee or tea may sound divine to some, but it could have negative impacts for the children of people who are pregnant, according to a new study.Ĭhildren who were exposed to small amounts of caffeine before birth were found on average to be shorter than the children of people who did not consume caffeine while pregnant, according to the study published Monday in JAMA Network Open.Ĭhildren of parents who consumed caffeine while they were in the womb were shown to be shorter in stature at age 4 than those whose parents did not - and the gap widened each year through age 8, according to lead author Dr. It’s not all good news, however, since excessive caffeine consumption of more than four standard cups of coffee per day can have an adverse effect on cardiac health and disrupt sleep. There are few things in life that come with as many upsides and as few downsides as caffeine. Caffeine helps us stay awake, increases our ability to focus, and gives everything a silver lining, all while actually being good for our overall health. We love the taste, sure, but we’d be lying if we said our initial infatuation with coffee wasn’t sparked by its caffeine content. Mild consumption of caffeine in one to four cups of standard coffee per day is generally considered safe and might be linked with an overall reduced mortality rate. On the other hand, coffee has been shown to be good for heart health! Too much caffeine – equivalent to more than four cups of coffee per day – can be dangerous and increase the chance of developing heart problems. When you drink a cup of coffee, your heart rate and blood pressure can increase, making coffee consumption safe only for people without any underlying heart conditions. Another receptor called the A2A receptor controls our mood by regulating the amount of the neurotransmitter dopamine.īesides being a psychoactive substance, caffeine is also a stimulant. Over the course of a day, more adenosine binds with A1 receptors, making us feel sleepier as nighttime and sleep approach. When adenosine binds with A1 receptors, it promotes relaxation and sleep. Two of the most important are A1 receptors and A2A receptors.
Adenosine has several receptors, each with its own effects. In our brains, receptors can bind with certain molecules to elicit neurological responses. Chemically, caffeine is very similar to adenosine, and this similarity is what allows caffeine to interact with our brains.īefore we can understand how caffeine works, we must first understand adenosine.Īdenosine is an organic compound that has a variety of effects on the human brain and plays an important role in regulating sleep and balancing brain activity and mood. Caffeine is a psychoactive substance, meaning it affects how your mind works and can alter your mood, consciousness, and cognition.
