Why is Coffee Popular?
Coffee is a popular stimulant. People believe that it ‘kick-starts’ brain functions and keeps you more alert and active. The main ingredient in coffee that produces this result is caffeine. You start to get drowsy when the chemical Adenosine generated by daily activity combines with Adenosine receptors in your brain. Caffeine keeps the two from combining by attaching itself to the Adenosine receptors. Besides, caffeine induces the pituitary gland to stimulate production of Adrenaline which has you wide awake. Adrenalin causes the release of blood sugar into the blood for extra energy. Caffeine also increases the dopamine levels in your system and jerks you awake. Caffeine causes the brain’s blood vessels to constrict, reducing the severity of a vascular headache.
