WTN: For many, the day starts with a cup of strong coffee which has caffeine as the main substance to give energy for the whole day’s efficient working. Caffeine has capacity of stimulating the human central nervous system. It is the world's most used psychoactive drug. Psychoactive drugs are elements which have the capacity to change functioning of the mind and results into alteration of mood, perception and consciousness.
Caffeine is commonly obtained from seeds of coffee plant, leaves of the tea bush and kola nuts. Across the world, mostly people consume caffeine in form of tea, coffee, soft drinks, energy drinks and other drinks made up with chocolate substance. Caffeine is also available as tablets and inhalers. The primary effect of caffeine is that it reverses the effect of adenosine. Adenosine is a neuro-modulator which plays a vital part in promoting sleep and weakening arousal effects. It also regulates flow of blood in various organs of the body. Thus caffeine is a substance which works as an anti-sleep element and reduces effect of adenosine in the body. Caffeine is known as a stimulator for certain parts of the autonomic nervous system.
Autonomic nervous system is part of human mind which controls the bodily functions including breathing, digestive process and heartbeat. Prevention of bronchopulmonary dysplasia in conceived baby, Parkinson and some kinds of cancer medicines contain caffeine as an essential element. Use of caffeine is also associated with weight gain during pregnancy and is held beneficial for women with below average weight. Heart-related diseases including coronary artery and stroke are less likely to occur with use of caffeine-containing beverages. Due to its hard hitting effect directly on the central nervous system, caffeine is known to reduce fatigue and induce feeling of freshness. Caffeine can make slight difference in the performance of athletes by improving sprint and increasing stamina.
Moderate doses have been associated with improvement in memory even in times of sleep deprivation. Yet, caffeine is not regarded as a good choice to enhance work capacity. Sleep disruption is considered to be aftermath of caffeine consumption, especially in evening or night. Recommendation of limiting consumption of caffeine is made for pregnant women. Caffeine may harm an adult if intake exceeds 10 grams. How much caffeine a cup of coffee contains depends upon the kind of bean used to prepare the coffee, yet approximately 80 mg to 175 mg is the normal scale. Another measuring factor is the process through which the beverage has been prepared - drip, expresso, percolation etc.
Thus only consuming around 50 to 100 cups of coffee would make a person face trouble. The caffeine form got in coffee goes through a long process of preparation and loses its extreme effects of pure caffeine. Over a long period of regular consumption, people tend to become habitual of the beverage resulting in symptoms of headache, irritation, uneasiness and sleepiness if the person doesn't intake the particular drink. Some people find blood pressure going up and faster heartbeat.
Many people get frequent urination if caffeine is not consumed, making it a chronic habit. Caffeine intake may cause high blood pressure leading to vasoconstriction, a condition in which blood vessels shrink and blood pressure increases. Long period of consumption of caffeine in high doses can result in chronic arterial stiffness - a prominent factor of heart functioning for purification. Caffeine and coffee consumption leads to gas-related issues. Caffeine can increase basal metabolic rate (BMR) which is the amount of energy needed for body function while the person is in inactive state.
Caffeine increases frequency of urination for as long as the consumption is on. This may result in dehydration at initial level though people consuming caffeine for long become accustomed and stop showing the symptoms. In women, high caffeine consumption, after reaching to menopausal state, may result in bone loss in long term. Caffeine may result in anxiety, insomnia and nervousness and effect working capacity of a person. Cancer risk is associated with caffeine use. People suffering from glaucoma may face increase in intraocular pressure making the condition worse. -Window To News
