It is but common that most of us feel a bit tired or dull after a strenuous workout or early in the morning, and might require some sort of boosters to up the momentum or gain the strength. In such circumstances, the one thing that immediately comes to mind is a Coffee Break or a Tea Break.
It is true that a sip of a coffee or tea will reinvigorate our senses and we tend to feel a bit more energized and pepped up to continue with our activities. Your power of concentration and mental alertness improves considerably and you feel much better prepared, in relative terms, to carry out the activities. Is it not? How could that be possible? Caffeine is the answer for this temporary rejuvenation.
A temporary spurt in our mental alertness as well as powers to concentrate can be felt following the intake of coffee or tea. It is for this reason that many of us tend to take up a cup of coffee or tea early in the morning, which will help us get going in the morning. In addition, intermittent breaks for coffee or tea at the workplace are just to pep up the alertness or concentration and help us get going.
The caffeine content included in coffee, or tea, which you took to refresh yourself, gets absorbed from the small intestine into the bloodstream and is carried to all the organs in the body. As a result, the heart rate is speeded up and the central nervous system gets stimulated. In addition, the production of digestive acids as well as flow of urine is increased and the muscles that control the blood vessels as well as airways are relaxed. This is the reason for the rejuvenated feeling in our mind after taking up a cup of coffee or tea.
It is essential that consumption of caffeine is kept under check and one should not become too much dependent on caffeine products to enhance his or her mental alertness. Though caffeine is not very harmful to the body, a sudden withdrawal of caffeine will have some minor disturbances. Some people might experience headaches, irritability and such other symptoms that vary depending upon the addiction to the intake of caffeine.
In general, caffeine is relatively non-toxic. If you consume about 80 to 100 cups of coffee or tea at a rapid pace continuously, then it might prove very fatal. Otherwise, caffeine is not harmful.
Some minor side effects might crop up depending upon the timing of your intake of caffeine. Ingestion of caffeine late in the day might result in a sleepless night, while excessive intake might lead to a syndrome called caffeinism, which is characterized by feelings of anxiety, irritability, insomnia, excessive urination and a rapid heartbeat. Increased consumption of caffeine might also lead to a modest rise in blood pressure, and older patients suffering from hypertension are advised to limit their consumption to one cup of coffee or tea per day.
Modest consumption of caffeine will help us to remain alert mentally with good concentration, and the good feeling will have a positive impact on our life style.
