If you’ve had too much caffeine or drank caffeine on an empty stomach, you may have experienced feeling jittery, anxious and/or restless. Because it’s a stimulant, it can increase heart rate and blood pressure, which impacts someone’s overall health. While most people only have mild negative effects from caffeine, both short- and long-term health risks are possible. Some of these examples are raised blood pressure, trouble sleeping, frequent urination, Long-Term Caffeine Health Risks, heart palpitations or other heart problems, and mental health changes. On the other hand, Brown says some evidence suggests caffeine can also lead to health benefits, such as decreased risk of stroke, Parkinson’s disease and dementia, when consumed in safe amounts.
In general, healthy adults shouldn’t have any more than 400 milligrams of caffeine each day. Among regular, black coffee or specialized coffee beverages from your favorite shop, you’ll consume anywhere from 50-500 mg of caffeine, depending on how many ounces you drink. If you’re trying to limit your caffeine intake, decaf is an option, but even a cup of decaf still contains small amounts of caffeine. A typical can has roughly 25-50 mg of caffeine. Unlike coffee, caffeine-free sodas or pops really are free of caffeine. Compared to coffee, tea is a relatively low-caffeine alternative. A cup of tea only contains roughly 5-50 mg of caffeine.
Energy drinks contain the most caffeine in the least fluid ounces. This caffeinated option has 25-150 mg in only one to eight ounces. For example, a 16-ounce energy drink could contain as much as 300 mg or more of caffeine.
To sum up, if you develop headaches when you don’t drink caffeine, it may be time to limit the amount of caffeine you’re drinking on a daily basis. If you’re concerned about how much caffeine you should have in the first place, talk to your primary care provider.
