A new study has found that drinking coffee in the morning can lead to increased feelings of happiness and reduced feelings of sadness and irritability. Researchers from the University of Warwick and Bielefeld University analyzed data from over 230 participants and found that caffeine intake was associated with a boost in positive affect, particularly within the first 2.5 hours after waking.

The study also found that there were no differences in the positive effects of caffeine between individuals with varying levels of caffeine intake, sleep problems, or mental health conditions like anxiety and depression. Previous studies have also linked coffee consumption to potential health benefits, such as reduced all-cause mortality risk and cardiovascular disease risk. The senior author of the study, Professor Sakari Lemola, noted that caffeine consumption is widespread among both humans and animals, suggesting a long history of its use.

Overall, the study provides evidence that drinking coffee in the morning can lead to increased feelings of happiness and well-being, with potential health benefits as well. Further research is needed to fully understand the mechanisms behind these positive effects of caffeine consumption.
