Although caffeine-rich beverages like tea and coffee are consumed widely, there is widespread confusion about what caffeine is and how exactly it affects our body. Given below is a detailed discussion of some of the important questions that you must have had about this substance.
What is Caffeine?
Caffeine is a substance that falls under the category of CNS stimulants. In simple words, these are a group of medicines that affect the central nervous system and stimulate it to restore alertness to metal faculties. This natural stimulant is used worldwide and is infused in soft drinks and energy drinks apart from tea, coffee, and chocolates. Naturally, it is found in seeds, nuts, or leaves of certain plants mostly found in South America and East Asia. The coffee bean is the most well-known source of caffeine.
Caffeine in Tea
The highest content of caffeine is found in shots of expresso which contains 240-720 mg. The caffeine content in tea is ranked after coffee and most energy drinks. Generally, brwed tea contains around 40-120 mg of caffeine. This can almost be called the caffeine sweet spot as it doesn’t harm sleep patterns even on regular intake but does lend a notable alertness to the drinker. The consumption of tea for its caffeinated effects goes back to several centuries when it was used by Japanese monks to stay alert during meditation.
How does it Work?
Caffeine is popularly known as the world’s most popular and widely consumed psychoactive drug. To explain the working of caffeine in simple words, it can be said that it blocks the action of a substance called adenoise and its receptor. This prevents the onset of drowsiness and prevents you from feeling lethargic. It is an instant solution to tiredness and might also act as a pain reliever.
The Benefits of Caffeine
As this substance is so widely consumed all over the world, several studies have been done to understand its effects on the body. While most of the results show that it has several beneficial properties, a few drawbacks of caffeine consumption have also been detected.
Firstly coming to the benefits of caffeine, there is nothing better than a cup of strong coffee or tea when you are required to pull off a night without sleep. Additionally, studies suggest that caffeine may also improve brain function, boost metabolism, help in weight loss and prevent heart disease. However, too much intake of caffeine has been found to result in complications such as headaches, improper sleep pattern, restlessness and anxiety. However, if taken in regulated quantities, caffeine is completely harmless for adults.
Recently, tea and coffee are not the only beverages available to the people which have high content of caffeine. Several beverages and drinks which are artificially caffeinated are available in the market and are easily within the reach of children. This is a growing cause of concern among parents and child health advocates.
