Caffeine Excess

Caffeine is probably the most widely consumed stimulant in the world. It is commonly found in coffee, tea, many sodas, and in small amounts in chocolate. In addition, it is often added to over-the-counter and prescription medications for headaches and pain (i.e., Excedrin, Anacin, and Fiorinal).

At lower doses, caffeine seems to help alertness and performance. At higher doses, it causes restlessness, agitation, and insomnia. Withdrawal (suddenly discontinuing) from caffeine can cause headaches, lethargy, irritability, and nausea.

Is Caffeine Bad for You?
1. It seems that in moderate amounts there are no significant long-term effects from caffeine use for most people. The only known risk seems to be increased Osteoporosis (i.e., bone loss). For women at risk for Osteoporosis, caffeine use should be limited. In addition, pregnant women should consume caffeine in moderation (contact your physician to determine exactly how much).
2. The amount of caffeine consumed in the world today has a devastating effect on the environment, as more valuable land (e.g., rainforests, etc.) is needed to plant more coffee beans. By limiting your consumption of coffee, you not only prevent addiction, but also help conserve valuable earth resources.
