Benefits of caffeine
The beneficial effects of caffeine are:
– it stimulates attention and concentration,
– removes fatigue and decrease reaction times.
Low to moderate doses of caffeine have the above effects.
The normal quantity of caffeine is 100 to 200 mg, meaning no more than two cups a day.
Besides coffee and tea caffeine is a useful storage. Although it contains only 60 mg of caffeine (about half that of coffee), a cup of tea can help revive your brain and instantly improve your performance. British researchers observed in a recent study that subjects who drank only water during the day had poor performance, while those who drank tea or coffee have maintained optimal cognitive awareness and activity throughout the day. Caffeine amplifies heart rate, blood pressure in vessels and may cause the occurrence of heart disease. Caffeine is also responsible for coronary spasm, the cause of about 20% of fatal heart attacks in healthy individuals.
Consumed in moderation, caffeine is useful, but at a certain dosage, adverse effects can overwhelm the positives. A second cup of coffee or 100 ml should be the maximum dose for a day. Do not forget cola, tea or chocolate, which consumed in large quantities, can have the same effect as coffee.
It turned out that people who drank coffee daily show a lower risk of developing diseases such as diabetes, Parkinson’s disease, colon cancer, gallstones, but also Alzheimer’s disease. It is possible that this was not solely due to caffeine. However, coffee contains some volatile substances and certain antioxidants that have positive effects.
For example, it seems that people who drink tea are less prone to diabetes, even in case that the assortment of tea contains caffeine. People who drink decaffeinated coffee still show a low risk to have diabetes, even if the beneficial effects of prevention will be halved.
It certainly looks that a frequent consumption of caffeine reduces the risk of diseases such as Parkinson’s and Alzheimer’s disease. Coffee has the advantage that not only stimulates the brain and central nervous system, but also protects them. Caffeine will not increase your IQ, but will maintain a state of alert and will improve the ability to concentrate
Caffeine is known for its beneficial effects on physical performance. Precisely for this reason, caffeine was considered, until recently, a component that artificially improves athletic performance. However, unlike existing products on the market – which have only this purpose – you can use caffeine without putting your health at risk. If you drink a cup of coffee an hour before the exercise session you might find that you are faster, stronger and more resistant.
If you drink coffee or caffeinated fluids frequently, then chances for you to feel any negative effect of caffeine consumption are very low. These negative effects are harmless and usually only lasts a few days. You can reduce the negative effects if you decrease the intensity of coffee drinking over several weeks.
