29 Aug 12 Caffeine: The silent killer of emotional intelligence
Want to up your emotional intelligence (EQ), improve your social skills? One way is to cut down on caffeine. The catch? As any caffeine drinker can attest, this is easier said than done.
The Good: Isn’t Really Good
Most people start drinking caffeine because it makes them feel more alert and improves their mood. Many studies suggest that caffeine actually improves cognitive task performance (memory, attention span, etc.) in the short-term. Unfortunately, these studies fail to consider the participants’ caffeine habits.
New research from Johns Hopkins Medical School shows that performance increases due to caffeine intake are the result of caffeine drinkers experiencing a short-term reversal of caffeine withdrawal. By controlling for caffeine use in study participants, John Hopkins researchers found that caffeine-related performance improvement is non-existent without caffeine withdrawal.
In essence, coming off caffeine reduces your cognitive performance and has a negative impact on your mood. The only way to get back to normal is to drink caffeine, and when you do drink it, you feel like it’s taking you to new heights. In reality, the caffeine is just taking your performance back to normal for a short period.
The Bad: Adrenaline
Drinking caffeine triggers the release of adrenaline. Adrenaline is the source of the “fight or flight” response, a survival mechanism that forces you to stand up and fight or run for the hills when faced with a threat. The fight-or-flight mechanism sidesteps rational thinking in favor of a faster response. This is great when a bear is chasing you, but not so great when you’re responding to a curt email.
When caffeine puts your brain and body into this hyper-aroused state, your emotions overrun your behaviour.
Irritability and anxiety are the most commonly seen emotional effects of caffeine, but caffeine enables all of your emotions to take charge.
The negative effects of a caffeine-generated adrenaline surge are not just behavioural. Researchers at Carnegie Mellon University found that large doses of caffeine raise blood pressure, stimulate the heart, and produce rapid shallow breathing, which deprives the brain of the oxygen needed to keep your thinking calm and rational.
The Ugly: Sleep
When you sleep, your brain literally recharges, shuffling through the day’s memories and storing or discarding them (which causes dreams), so that you wake up alert and clear-headed. Your self-control, attention, and memory are all reduced when you don’t get enough…..
