The working ingredient of coffee is caffeine. So what does caffeine do?
Adenosine builds up and minimizes the communication in the nervous system when your brain gets depleted of energy. It then tells the brain to stop if you’ve done enough work.
On the other hand, caffeine works by telling the adenosine to go away, and the brain to start working back again. It blocks the adenosine build-up, by binding on to the adenosine receptors, which prevents you from feeling tired.
But our bodies might say otherwise.
Your tiring brain will get exhausted and will simply build new adenosine receptors if you frequently drink coffee and the caffeine molecules continue to block the adenosine receptors.
It then becomes a vicious circle because you now have to drink more and more coffee to feel the same wakefulness effect as before.
Which means that if you’ve stopped drinking coffee now, you would feel way more tired, than you would have felt without coffee, in the first place.
So this adaptation creates some kind of addiction, which makes you crave for a cup of coffee day in and out that later affects you in the long run – productivity-wise.
Coffee contains more than 1.000 compounds with tons of antioxidants. Antioxidants help slow down aging, make you recover faster and prevent cancer.
So is coffee bad? It depends.
If your main reason to drink it is to increase productivity – drink it sparingly.
Your body adjusts to the caffeine and builds adenosine receptors, which make you feel more tired than before. It can also interfere with your sleep pattern and your ability to relax.
Caffeine has a half-life of 6 hours, which means it takes about 2 full days to completely clean it out of your system. It can still mildly affect your sleep quality during this time.
Healthwise, well it depends on what coffee you're drinking, how much you're consuming, what your body can take and many more factors. Each body is different, which means each person will respond to coffee consumption in a unique way. We recommend seeking advice from your health professional.
