![]() ![]() Biobank data of more than 347,000 people ages 37 to 73 years to explore how the caffeine-metabolizing gene (CYP1A2) helps carriers process caffeine, as well as identify the risks of cardiovascular disease as it relates to coffee consumption and genetic variations. In the study, researchers delved into U.K. Play icon The triangle icon that indicates to play → Get Bicycling All Access for the latest cycling and health news! Thanks to research from the University of South Australia conducted in 2019, we now have an upper limit for how much coffee is safe when talking about your heart disease risk. ![]() Too much caffeine can cause high blood pressure, a precursor to heart disease, and can cause side effects like dizziness, shakiness, headache, or abnormal heartbeat. But as with any good thing, too much coffee-too much caffeine specifically-is a bad thing. For many, life without at least one daily cup is simply a no-go. Endurance athletes swear by java to get them going (in more ways than one). But drinking some coffee is also better than not the same study found that nondrinkers had an 11 percent higher risk of cardiovascular disease.įor billions of people around the planet, coffee is fuel for the daily grind.Research published in the American Journal of Clinical Nutrition in 2019 has found that the upper limit for coffee consumption is six cups a day.Coffee is a must-have to start the day for many cyclists, but too much caffeine has been shown to raise blood pressure, and may also lead to things like headache, shakiness, or abnormal heartbeat.Caffeine also disrupts sleep by antagonising the brain’s A1 receptor, which has an important role in helping people sleep, and this can explain why caffeine makes people feel more alert while increasing their risk of insomnia. Caffeine antagonises the brain’s A1 and A2 adenosine receptors, explaining its effects on the body’s motor activity, such as boosting exercising activity or increasing physical agitation. Drinking coffee and other caffeinated products has significant effects on the brain and body because caffeine interacts with the dopamine system. Caffeine is highly addictive because it activates reward-orientated mechanisms within the brain, giving people unpleasant withdrawal symptoms such as headaches or brain “fog” when they stop or reduce it. The psychoactive effects of caffeine are similar to some of the effects of stimulant drugs such as amphetamines or cocaine. Further longitudinal research is needed to explore whether people who consume a high amount of caffeine are at greater risk of psychosis.Ĭaffeine is clinically classed as a drug because it has significant effects on the brain and body. The patient was also experiencing delusions of reference (a type of delusion involving thinking that trivial or innocuous things have great personal significance or meaning) by being preoccupied with the number 33. The patient sought help because of hallucinations that involved seeing things that were not there and having paranoia about being followed. Another clinical case study reported a patient who had been drinking several cups of coffee and energy drinks each day. The patient’s psychotic symptoms subsided naturally after reducing caffeine consumption for 7 weeks without taking any anti-psychotic medicine. One study described a patient who started suffering from paranoia and delusions after consuming a large amount of caffeine. Clinical case studies suggest that caffeine can induce psychosis in otherwise healthy people. ![]()
