Inc. Magazine published an article about a TalentSmart LinkedIn post which relies on a Johns Hopkins Medical School study which concludes that a habitual daily cup of coffee before your work day begins may actually give you the wrong attitude for business and may lead to a decrease in your productivity:
“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,” Bradberry explained. “In reality, the caffeine is just taking your performance back to normal for a short period.”
It gets worse. Bradberry goes on to explain why coffee also results in a loss of inhibitions. He says that caffeine triggers the release of adrenaline–a.k.a. the source of the “fight or flight” response.
“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,” Bradberry writes.
