We have brains. Our brains have neurons. Neurons produce adenosine.
Adenosine makes us sleepy or calm, it makes us tired when it’s time to sleep. When we drink coffee and caffeine enters our body, it acts as an adenosine imitator. Caffeine immediately targets the adenosine receptors and is absorbed into our bodies.
Caffeine may be a good imitator of adenosine, but it does not have the same effect. Instead of activating the receptors, it has a blocking effect. Caffeine therefore inhibits the adenosine receptors which normally make us tired.
Hocus Focus!
Coffee does not make us more active, but it does slow down our feelings of being tired. Caffeine has an impact on our alertness and makes us work faster. According to research, an intake of 75mg of caffeine increases our alertness for approximately four hours.
As well as blocking the adenosine receptors, caffeine also stimulates our central nervous system by releasing other neurotransmitters, including dopamine and serotonin. These have an impact on our emotional behaviour and make us happy when released by the brain.
Caffeine causes various changes that can have a positive impact on mood, alertness, learning and resilience.
Why do we keep wanting more?
Our body perceives caffeine as an adenosine imitator and begins to produce more adenosine receptors, which means more caffeine is needed to achieve the same effect – this is why caffeine is addictive.
Of course, like anything, too much caffeine also has negative effects, but moderate consumption clearly has primarily positive effects!
