Coffee calms me down

I am a lover of coffee. I can down at least three cups a day. Well, I am a fanatic of every coffee and I think this makes me sane whenever I get into pressure at work. My boss recently told me to look for a nas server test which I couldn’t find in the internet. Luckliy, I found one two days before my deadline. As a relief of course, I treated myself with some coffee in the nearest coffee shop.

Most people take coffee to increase alertness and concentration, improve mental and physical performance, and counteract fatigue. I personally rely on coffee to perk me up in the morning, and at other times of the day when my energy level tends to dip. This energizing effect is due to a substance called caffeine, that is found naturally in plants such as coffee beans, kola nuts, tea leaves and cacao. Synthetic caffeine is also added to energy drinks and snacks and some prescription and over the counter medications such as cold tablets and diet pills. Notwithstanding these benefits, caffeine can also be harmful and, in extreme cases, even fatal. Among healthy adults, too much caffeine may result in unwanted symptoms such as irritability, palpitations, anxiety, nervousness, tremors, hyperacidity and inability to sleep.

Caffeine (by definition) is a drug that acts as a central nervous system stimulant. Like other drugs, it has both benefits and risks, and as such can be subject to abuse and addiction. Regular intake of caffeine may result in tolerance or a decreased responsiveness to its stimulant effects; it also leads to dependence, and its sudden removal can induce withdrawal symptoms such as headaches, nausea and drowsiness.
