What is Caffeine and Where Does It Come From?

How Does Caffeine Work?
Caffeine is a stimulant that affects the central nervous system. It helps people stay alert, feel less tired, and increase energy. Caffeine is usually absorbed by one’s body within 45 minutes. It will have a peak effect around 15 minutes to 2 hours after consumption. Caffeinated drinks are absorbed quickly and are broken down by the liver.
Although caffeine will give you a burst of energy it can also cause some unpleasant effects such as increasing the release of stomach acids which could lead to an upset stomach or heartburn. It can interfere with the absorption of calcium in the body and could increase blood pressure. Many people notice that after their morning coffee they have to use the bathroom. This is because caffeine works as diuretic. It can cause you to urinate more and possibly become dehydrated.
Can Caffeine Cause Bad Side Effects?
Some individuals will have side effects from caffiene if they are sensitive to it or consume too much. Possible side effects include restlessness, jitters, insomnia, headache, increased heart rate, dizziness, dehydration, and anxiety.
If you consume caffeine regularly your body will build up a tolerance and dependency for it. You will need more caffeine in order to feel the same effects. If you decide to stop consuming caffeine suddenly you could have withdrawal effects such as tiredness, headache, irritability, and agitation. These will eventually go away but it is a good idea to taper the amount of caffeine you drink instead of stopping suddenly.
