Caffeine power: happier through coffee – new study reveals secrets!

A newly published study from Bielefeld University and the University of Warwick, which appeared in the journal Scientific Reports, shows that caffeine plays a significant role in influencing the mood of young adults. The study, which followed 236 participants over a period of up to four weeks, found that consuming coffee, especially in the morning, can significantly improve mood. aktuell.uni-bielefeld.de reported that after drinking coffee, respondents experienced more happiness and enthusiasm, while negative emotions such as sadness and anger decreased significantly.

The results were remarkably clear: After consuming coffee, participants reported less sadness and anger compared to days when they did not consume coffee. Interestingly, the mood effects were unrelated to the time of consumption and showed no differences in people with varying consumption habits or psychological problems such as depression or anxiety. These findings open new perspectives on the beneficial effects of caffeine, whose main mechanism is blocking adenosine receptors in the brain, resulting in increased alertness and energy.

Caffeine withdrawal and the stress response

However, despite caffeine's benefits, it is important to keep in mind the potential negative effects of high caffeine consumption. onmeda.de explains that abruptly stopping caffeine can lead to physical and psychological withdrawal symptoms. The most common symptoms include headaches and irritability, especially if coffee consumption is suddenly reduced or stopped altogether. Since caffeine has a psychostimulant effect on the central nervous system, sudden withdrawal can cause significant difficulties.

Caffeine not only stimulates alertness and increases the release of dopamine, but also increases the production of stress hormones such as adrenaline and norepinephrine. These hormones can constrict blood vessels and increase blood pressure, causing some health concerns, especially with excessive late-night consumption.

Health aspects of caffeine consumption

The health effects of caffeine go beyond influencing mood. Loud gesundheit.de Caffeine increases heart activity, dilates the bronchi and can therefore increase performance. In small doses, it helps improve concentration and eliminate symptoms of fatigue. These effects also have positive effects on athletic abilities, as the muscles are better supplied with oxygen.

In summary, while caffeine may promote improvement in mood and alertness, awareness of the risks associated with overconsumption and sudden withdrawal is essential. This complex relationship between caffeine, mood and health requires nuanced consideration, especially in today's society where approximately 80% of adults consume caffeinated beverages.
