In ancient health, many people assume that coffee and tea are not very good drinks for health. However, the modern ensured that both of these drinks we can include in the category of healthy beverages. Caffeine drinks have benefits for relaxation, improving blood circulation and even helping to control the rise in blood sugar. Besides, caffeine also copes with stress and improve concentration.
However, an essential note of coffee and tea is that you are actively discouraged from excessive consumption. Moderate doses are safe, but it becomes unsafe if you consume them excessively. The caffeine in coffee is much more than tea. However, you should be cautious in regulating your daily caffeine intake.
When the caffeine you consume exceeds the body’s tolerance limit, there may be some caffeine side effects that can also develop into serious health problems. In general, drinking black coffee at least 2 cups a day, it is still relatively safe. But in some people, tolerance can grow up to 4 cups a day.
Then, what are the actual reactions of the body that may arise when you drink coffee and tea with excessive amounts? What are the possible dangers of excess caffeine? Here are the side effects of caffeine overdose:
The side effects of too much caffeine
Caffeine affects the production of enzymes and hormones in the brain. The hormone adenosine causes drowsiness. Any activity you do will produce this hormone. The accumulation of high adenosine, it will cause drowsiness and relax the blood vessel and nerve tissue. Caffeine will suppress the body’s response to adenosine. The body is no longer sensitive to signals from adenosine. Adenosine has a task to give a relaxing effect, and when the body no longer gets stimulation from adenosine, the nerves will not experience a relaxing effect.
Caffeine increases the hormone norepinephrine and epinephrine, which triggers the body to be more alert to concentrate. Thus, excess caffeine will trigger a person to difficult to feel relaxed and difficult to sleep. In general, the effect of caffeine can last for 5 hours, but the influence of coffee is quite complicated, it depends on the consumer’s tolerance and caffeine levels. As you know, energy drinks have caffeine levels about three times higher than a cup of coffee.
Caffeine side effects inhibit the performance of adenosine hormone receptors that trigger fatigue in the brain. But when the doses of caffeine you consume are excessive, the impact of caffeine will lead to anxiety and excessive alertness. Caffeine also triggers the production of adrenal hormones that trigger a stronger heart rate. Excess caffeine allows your heart rate to work faster. The caffeine effect on cell relaxation causes a strained impact on the nervous system that also triggers the effects of stress.
3. Digestive problem
The side effects of caffeine have close links with digestive issues. Some people with stomach problems cannot consume excessive caffeine. Their brains may still be healthy enough to face coffee, but their digestion has a lower tolerance for caffeine. Also, caffeine also triggers an increase in acid production of the stomach. Caffeine can also aggravate gastritis complaints because increases in gastric acid levels trigger stomach irritation.
4. Easily tired
Caffeine will encourage the body to increase energy production, but this will also make your body more likely to feel tired. When you drink coffee in the morning, this will help your body fresher. It’s just that when the levels of caffeine in the body go down, the body’s reaction will work the other way around.
As long as you move, the body keeps producing adenosine hormones; it’s just that your body cannot read them because the caffeine reaction is still working. Once the caffeine effect is gone, the high accumulation of adenosine will trigger a powerful relaxation effect that causes the body to feel exhausted and eventually trigger a great sleeping effect. Excessive caffeine will cause the body to entirely insensitive to adenosine signals. Instead, the body will become extra tired.
5. Frequent urination
Caffeine does have a role in increasing the volume of urine because of the nature of diuretics. An excessive time you drink coffee, caffeine will make too excessive urine volume.
Caffeine side effects also trigger dependence due to caffeine consumption in the long term. However, these side effects are not as significant as in illicit drugs.
There is no definite influence of caffeine on the rise in blood pressure. But in those with cases of chronic hypertension, coffee consumption exceeds moderate levels can lead to an increase in blood pressure. It is related to the nature of caffeine that encourages the production of adrenal hormones and their effects on the nervous system. In addition to triggering a rise in blood pressure, caffeine also allows the heart rate. Under certain conditions, excessive consumption of caffeine leads to arrhythmia. In general, caffeine is still safe. But the medical side always advises keeping levels of caffeine consumption in safe levels for those with long-term hypertension cases and heart complaints.
Those are some conditions that can appear as side effects of caffeine. Caffeine is harmless, even beneficial to health. Even so, the stimulant effect is quite loud especially if you are overconsumption.
