Caffeine good or bad...??

Caffeine is a drug, popularly consumed in coffee, tea, soft drinks and, in smaller doses, chocolate. While we seem to have a love affair with these products, there’s been quite a bit of confusion and even controversy surrounding caffeine lately. Is it good or bad for us? Here’s a brief tutorial on caffeine, and some surprising answers to these questions.

Effects on the Body:

• Hormones- You can feel the effects of caffeine in your system within a few minutes of ingesting it, and it stays on your system for many hours—it has a half-life of four to six hours in your body. While in your body, caffeine affects the following hormones:
• Adenosine- Can inhibit absorption of adenosine, which calms the body, which can make you feel alert in the short run, but can cause sleep problems later. (More on this below.)
• Adrenaline- Caffeine injects adrenaline into your system, giving you a temporary boost, but possibly making you fatigued and depressed later. If you take more caffeine to counteract these effects, you end up spending the day in an agitated state, and might find yourself jumpy and edgy by night.
• Cortisol- Can increase the body’s levels of cortisol, the “stress hormone”, which can lead to other health consequences ranging from weight gain and moodiness to heart disease and diabetes.
• Dopamine- Caffeine increases dopamine levels in your system, acting in a way similar to amphetamines, which can make you feel good after taking it, but after it wears off you can feel ‘low’. It can also lead to a physical dependence because of dopamine manipulation
