Many people nowadays start the day with caffeine, which works by stimulating the central nervous system and the brain, by digesting coffee, energy drinks, tea, or other products that contain the substance. The reason we do this is simple: it makes us stay awake better and go through the day. But what are the exact effects and consequences of this widespread consumption of caffeine?
Caffeine stimulates the central nervous system and when it reaches the brain, it noticeably affects one by increasing his or her alertness and therefore feeling less tired. According to multiple studies, individuals who consume high-octane coffee on a daily basis had a decreased chance of acquiring specific diseases such as Alzheimer's and dementia, as well as a 45 percent lower risk of suicide. Caffeine has been shown to improve mood and cognitive function, increase metabolism and fat burning, improve exercise performance, protect against heart disease and diabetes, and many other benefits.
However, with benefits, there are also side effects. For example, it can cause headaches, which are connected to caffeine withdrawal. Anxiety, restlessness, tremors, irregular pulse, and difficulty sleeping are some of the negative effects of excessive use. For certain people, it can also cause migraines and elevated blood pressure; since it readily passes the placenta, it can also increase the risk of miscarriage or low birth weight too.
Therefore, it is important for us to weigh the benefits and drawbacks of caffeine. Keep in mind that caffeine doses of up to 400 mg per day and 200 mg each dosage are typically regarded safe and make wise decisions on consumption.
