Caffeine - how it works?
This substance is valued because of its stimulating effect. Caffeine works by stimulating the central nervous system, increasing concentration and improving mood. What's more, caffeine accelerates heart activity, increases the strength of its contraction and increases the metabolic rate. Caffeine has stimulant properties by acting on the cerebral cortex. It reduces fatigue and weariness and extends the time of concentration and better focus.
