I am a coffee-addict and I know, most of you are! Commonly, we know that coffee helps us stay fresh and awake… but rarely we know the actual impact of coffee on our brains.
One of the main ingredients of coffee is Caffeine which is supposed to affect the human brain in more than one ways. For instance, the first and foremost affect that coffee has over our brains is that it acts as a potent central nervous system stimulant.
|Impact Of Coffee On Your Brain – Good Or Bad?|
It increases the levels of alertness in a person.This is supposed to occur because, it blocks the synthesis of adenosine, which is a chemical that is responsible for making you feel drowsy. As, there the build up of adenosine in body is considerably reduced by coffee, you stay fresh and do not feel tired. Coffee resembles adenosine in chemical structure a lot and therefore blocks the adenosine receptors, thus, stopping the binding of adenosine to it’s receptors. In short, caffeine, acts as a chemical doppleganger of adenosine.
The effects that intake of coffee has on different individuals varies alot depending upon individual sensitivity and how a particular body system adapts to coffee. Also, the genetics have got a role to play.
The concentration abilities and attention span of a person are also improved, if, a person consumes moderate amount of coffee in a day. That is why it is not uncommon to find students consuming coffee during their exams to increase the wakefulness and therefore, avoiding drowsiness while studying. It is also a great alternative to shoo away the sleepiness in those who need to drive at night.
In moderate amounts, intake of coffee is found to increase memory performance and enhance retention of information by the brain. On the other hand, excessive intake of caffeine decreases memory performance probably due to over stimulation that is why the effects of coffee are more pronounced in occasional coffee drinkers as compared to those who take it on regular or daily basis.
A direct correlation has also been found between intake of coffee and sleep patterns. Intake of coffee alters the quality of sleep and number of hours of sleep. Abstaining from coffee, might actually help improve sleep quality.
Coffee as a substance does not produce any kind of physiological or neurological dependence.
However, stopping the consumption of coffee all of a sudden might produce certain kind of craving or withdrawal symptoms like: mild degree of headaches, drowsiness and reduced alertness in regular caffeine consumers. Though, these are mild and of short duration, only.WHO as well as several studies have confirmed that Caffeine is not linked to the brain’s circuit of dependence.
It is suggested by various studies that regular consumption of coffee, in moderate quantities throughout life, leads to a considerable decrease in chances of developing neuro-degenerative disorders like Alzheimer’s and Parkinsonian disease during the later stages of life. This is supposed to be due to presence of antioxidant, anti inflammatory and neuro-protective properties in caffeine as well as certain other constituents of coffee.
So, all in all, coffee in moderation is good for your brain but as it is with everything else, excess is bad.
