THIS IS WHAT HAPPENS TO YOUR BODY AFTER YOU DRINK A CUP OF COFFEE:
FIRST 10 MINUTES:
The caffeine enters your bloodstream. Your heart rate and blood pressure start to rise.
You start to feel more alert and focused. You find it easier to make informed decisions and handle problems. In addition, the caffeine can help you feel less tired by connecting to your brain’s adenosine receptors.
Your body starts to produce more adrenaline. This can lead to sharper vision because your pupils dilate slightly.
The level of serotonin in your body begins to rise. This improves the functioning of the motor neurons which, in their turn, increase muscle strength.
Coffee can increase the rate at which your cells release energy. When this happens, your body starts to break down fats, even if you don’t move. Caffeine also stimulates and increases the production of stomach acids.
The caffeine in coffee causes a diuretic effect. Apart from water, your body also loses some essential vitamins and minerals. This can lead to slight disorders of calcium metabolism.
