    Coffee includes a chemical called caffeine which is responsible for keeping the individual awake.

    In a normal human body, there is a chemical known as adenosine in every human cell. It has different functions among which is to act as a nerve system depressant. Every waking hour the quantity of adenosine increases in the body and eventually by night time the quantity is high enough to make us drop off to sleep. Now there are adenosine receptors that bind with adenosine to produce this effect.

    The caffeine is very similar to the adenosine. Therefore when we consume coffee the caffeine in it is incorrect for adenosine by the receptors and binds with them. Hence the caffiene effectively avoids the adenosine – receptor bonding which is the cause of sleepiness.

    It is necessary to keep in mind that the adenosine activity pointed out in the past is an important mechanism in the body and we are really disrupting it by drinking coffee. Use of coffee may briefly keep sleep at bay however it in fact makes you sleepier in the long run. Our bodies are an extremely developed machine and thus when it discovers that the amount of adenosine receptors are not enough to make the person drowsy, it increases the no of adenosine receptors in the brain. This new receptors bond with the REAL adenosine and the necessary impact is acquired by the body( drowsiness). So if you consume coffee frequently the no of adenosine receptors are increased in the brain and the increased adenosine – receptor pairing will trigger much more drowsiness and tiredness. Therefore you need more caffeine than before to deceive the receptors. This is why regular coffee drinkers require more and more powerful coffee as time goes by to get rid of sleepiness every morning.

    Adenosine and caffeine share a very similar chemical structure.

    When you consume coffee, caffeine molecules attach to the brain receptors that adenosine would normally connect to, thereby obstructing its attachment (think about a lock and crucial system with the caffeine/adenosine being the key and the receptors as the lock).

    What’s Adenosine?

    Adenosine serves as an inhibitory neurotransmitter, hence, it manages the nerve system to not get too promoted. Particularly, Adenosine helps your body prepare yourself to sleep as it gets launched increasingly more as the day advances, dilating your blood vessels, and slowing down your heart rate.

    Caffeine improves your concentration and awakening by the abovementioned mechanism– (basically) ‘deceiving’ your brain and not you (as in: your persona).

    Besides focus, Caffeine also has the capability to enhance your memory as shown in various research studies yet.

    The other compounds in coffee have actually shown the greatest benefits– I’ll enjoy to broaden on that in another concern. So, every cup of coffee will keep you awake for 30 min – 2 hours more according your body condition and stats.
