Effects of Caffeine on Your Body


Coffee is a drink commonly known for its use of creating alertness for the brain. However, it is also a central nervous system stimulant and affects the body in many ways. The following information may make you rethink drinking coffee to promote its effects and ensure health.

Caffeine provides no nutritional value on its own and has no taste, so you may not be aware of the presence of caffeine in your food. Some drugs may even contain caffeine without our knowledge.
Is caffeine good for health? Caffeine is the ingredient that almost always causes some symptoms. At a minimum, we can feel energized after taking them, but over time, too much caffeine can trigger symptoms of addiction. If you're healthy, it's perfectly normal and safe to consume about 400 milligrams of caffeine per day. However, keep in mind that a standard size cup of coffee is 8 ounces. So it's important to pay attention to the size of the cup of coffee you drink so you know when to stop.

Many studies have shown that caffeine acts as a central nervous system stimulant. When it comes to its effects on the brain, what comes to mind right away is creating alertness. You'll feel more alert and less tired when you consume caffeine, as it's a common ingredient in medications that treat sleepiness, possibly headaches, and migraines.
Not only that, many studies also show that regular coffee drinkers have a lower risk of developing Alzheimer's disease and dementia, and reduce the risk of suicide by 45%. However, these benefits are actually limited to high-octane coffee drinkers and not decaf coffees. Some people consider coffee a healthy drink, but like most foods, when your body consumes too much caffeine, it's not really healthy.
Headaches are one of the first reactions that you may notice when consuming a lot of caffeine. This is mainly related to caffeine withdrawal syndrome. Because when the blood vessels in the brain get used to the effects of caffeine, if you suddenly stop consuming caffeine, it can cause a headache. Other symptoms of caffeine withdrawal include anxiety, irritability, and drowsiness. In some people, cutting caffeine doses suddenly can cause tremors. Although extremely rare, caffeine overdose can also cause symptoms such as confusion, hallucinations, vomiting, and death from convulsions. Overdose occurs when large amounts of caffeine are consumed in the body.
