Nevertheless, anyone who knows even a little bit about scientific testing knows that the rats get it first! The results of the trial have been published in the "Journal of Agricultural and Food Chemistry". The report indicates that generally just smelling coffee alleviates the stress levels of the sleep-deprived rats.
So, I am going to drink more coffee today or at least go to Starbucks, Gloria Jeans, or the Coffee Bean and buy some fresh roasted beans to sniff because I am sleep-deprived after having watched the US Open Golf. As it turns out I could have stayed asleep as Tiger Woods and Rocco Mediate have to go at it again today in a playoff!
It seems like catch-22 to me as the drinking of the coffee keeps you awake and causes stress increases but the aroma of the beans reduces that stress, weird! Apparently, previously studies have shown that coffee consumption reduces depression and the risk of suicide. All this time I just thought these big coffee drinkers were just wired on the excess caffeine but in fact they were not wired but enjoying levels of reduced stress.
In any event if you want to learn more about current coffee research you should go here, The Coffee Science Information Center or CoSIC.
