Research carried out by scientists from universities of Bielefeld and Warwick reveals that regular consumption of coffee, especially in the morning, would have a positive effect on the regulation of emotions. By following 236 young adults for four weeks, the researchers observed a clear improvement in good humor and enthusiasm on the days when participants consumed coffee. This work sheds new light on the role of caffeine in our well-being and could relaunch debates on its long-term effects.
Morning coffee, an ally for energy and morale
According to the study published in the journal Scientific Reportsthe researchers followed 236 German participants For four weeks to assess their emotions and their coffee consumption habits. Volunteers filled short questionnaires several times a day on their mood and consumption of caffeinated drinks.
The results are clear: the mornings with coffee are accompanied by a more positive mood, a renewed enthusiasm and better vigilance. This observation is valid Even in people with sleep disorders, anxiety or depressive symptoms. Researchers believe that caffeine acts by blocking adenosine receptors, a molecule involved in the feeling of fatigue, which indirectly promotes better production of dopamine, often associated with motivation and pleasure.
These conclusions could nourish wider reflections on the physiological and psychological effects of caffeinated drinks, a subject that is increasingly interested in health professionals. A space could be dedicated to additional resources.
Beneficial effects, but which deserve clarification
If the improvement in mood seems confirmed, the researchers remain cautious: they cannot determine with certainty if this well-being stems directly from the chemical effects of caffeine or a reduction in withdrawal symptoms after a night without consumption. As the professor reminds us They have realo“Caffeine blocks adenosine, but other factors are probably involved”.
The authors also note that coffee consumption could alleviate certain feelings of sadness or annoyance, but the effect is less marked than that observed on good humor. In Francewhere the inhabitants consume About 5 kg of coffee per yeareither two cups per daythese results could feed the debates on the balance between pleasure, health and eating habits. A box could offer comparative figures for other countries. This research opens the way to new studies aimed at understanding the precise influence of caffeine on the human brain and its role in the regulation of emotions.
