There is a prevailing attitude when it comes to caffeine. Because we like, we want and we want because it makes us feel good, better able to deal with our boss or a group of children. But when we take, we feel guilty, suspecting that eventually will hurt us. But here I bring some myths and facts about coffee.
- It is said that coffee consumption in the long run harm the body: That is false and there is partly due to smokers who metabolize coffee two times faster than nonsmokers who drink more coffee. And smokers have more health problems, but it is the nicotine, not caffeine. As long as you do not have high blood pressure, cardiac arrhythmia or anxiety, drinking caffeinated beverages can for many years without problems.
- Caffeine alters the body chemistry: That’s true because it is a natural stimulant and 250 milligrams, which is about two cups of strong coffee, three times the amount of adrenaline in our blood, our breathing rate increases. In the brain, caffeine intercepts adenosine, the chemical that puts our nerves slower and makes you want to sleep. It also increases dopamine levels, stimulating pleasure centers. So has the magical ability to make us feel alert and relaxed at the same time.
- The caffeine makes us more ready: That’s true and have a cup of coffee before writing an essay is not a bad idea. Caffeine improves cognitive functions, which blocks the chemical that makes the brain more slowly.
- Caffeine improves athletes: It is true because in terms of quality athletic caffeine can be the difference between the first and last. No Caffeine, besides being mentally slow, we are physically. This element encourages you exercise 10 to 15 percent because it prevents us feel tired.
- Caffeine causes high blood pressure: It is false and some studies reported that caffeine does not put us at risk for hypertension, although more is not known, which is sugary sodas and tail if you do. However, if you already have high blood pressure should avoid excessive consumption because it can increase an existing condition.
