A study by Japanese researchers found that simply inhaling the aroma of freshly brewed coffee can lead to reduced feelings of fatigue, anxiety, and other negative emotions. The study involved 20 students aged 20 to 29, who were exposed to the coffee aroma for five minutes without drinking it. The participants' moods and brain activity were evaluated before and after the exposure. While the aroma did not affect heart rate, it did increase a relaxation index measured by EEG.
