Caffeine is a central nervous system stimulant that promotes the effect of alertness in an individual. Henceforth, it is commonly found in medications used to treat headaches, migraines and drowsiness. While many of us are reliant on a cup of coffee in the morning or an energy drink during the day, caffeine affects your body in many different ways.

Alert Brain: Caffeine temporarily relieves drowsiness and fatigue and promotes a sense of alertness, which may be helpful to those who have a slow start to the morning.

Decreased Suicide Risk: A study shows the the mood-enhancing properties of caffeine contributed to a 45 percent lower risk of suicide in participants.

Increase in Blood Pressure: Caffeine may temporarily raise your blood pressure which is especially noticeable if it is consumed before a workout or other physical activity.

Heartburn: This is caused by the acidity of many caffeinated beverages such as coffee and soda.

Confusion: Over-stimulating the brain with caffeine may lead to confusion and fogginess.

Caffeine in the Bones: Caffeine interferes with the absorption of calcium into the bones, which over time will cause bones to break more easily.
