Is Caffeine Safe to Drink?<\/h2>\n

\u201cModerate caffeine consumption is generally considered safe but should be consumed mindfully as it can affect people differently,\u201d Rachel Bult, an OSF HealthCare dietitian, said.<\/p>\n

The Food and Drug Administration (FDA) recommends keeping your daily caffeine intake below 400 milligrams \u2013 about three to four cups of coffee.<\/p>\n

Pregnant women and people with heart conditions should consume even less. It\u2019s generally recommended to limit caffeine to no more than 200 milligrams per day \u2013 about the amount in one cup of coffee. However, many experts, including the American Pregnancy Association, advise that the less caffeine you have, the better.<\/p>\n

One of the risks of consuming caffeinated beverages is that many of these drinks are high in sugars and fat \u2013 such as coffee, soda and energy drinks.<\/p>\n

\u201cConsuming these kinds of drinks in excess can lead to diabetes, obesity and heart disease,\u201d Rachel said.<\/p>\n

How much caffeine is safe for teenagers and children?<\/h3>\n

Caffeine affects children and teenagers differently than adults. Since their bodies are still developing, they are more sensitive to its effects. High caffeine intake in young people can lead to increased heart rate, difficulty sleeping and anxiety. Experts generally advise that children and teenagers avoid caffeine or consume it in very limited amounts.<\/p>\n

The American Academy of Child & Adolescent Psychiatry<\/a> (AACAP) recommends children 12 and under shouldn\u2019t drink caffeine and teens ages 12-18 can consume up to 100 mg of caffeine per day. That\u2019s about one cup of coffee or two cans of soda. The American Academy of Pediatrics also says children and teens should not drink energy drinks<\/a>.<\/p>\n

There is also a small risk of caffeine overdose<\/a>, which can lead to\u00a0vomiting, high blood pressure, racing heart, heart rhythm problems, disorientations and hallucinations. This is even more common in people with preexisting conditions, like heart problems, seizures and migraines.<\/p>\n

How does caffeine affect your body?<\/h2>\n

Caffeine works by blocking adenosine, a chemical in your brain that normally makes you feel tired. This makes your body feel alert and energized. It may also make you feel like you\u2019re able to focus better.<\/p>\n

\u201cModerate amounts of caffeine have been linked to improved health outcomes such as lowering the risk of Parkinson’s disease, Type 2 diabetes and cardiovascular disease. It also contains some beneficial antioxidants,\u201d Rachel said.<\/p>\n

However, that caffeine boost doesn\u2019t last long. It can create unpleasant side effects \u2013 like coffee jitters \u2013 that stick around past the caffeine crash.<\/p>\n
