Experiments on mice have shown that sweet coffee affects biological clocks. Japanese scientists conducted experiments on mice and found that caffeine with sugar or artificial sweeteners affects circadian rhythms much more strongly than caffeine dissolved in water. The study was reported by "Tsargrad" with reference to the Science of Food journal.
In the experiment, the mice were offered a caffeine solution. In one case, it was simply caffeine dissolved in water, and in another case, it was sweetened with sugar or saccharin. Regardless of the taste of the drink, the mice consumed it in the same amount. However, mice that drank the sweet caffeine solution stayed awake for longer. Some of the test subjects even started to become active during the day instead of at night.
Japanese researchers hypothesized that the sweet caffeine solution triggers conflicting signals in the body and contributes to the release of dopamine. This leads to changes in biorhythms. In the future, scientists plan to conduct further research on the influence of caffeine drinks on dopamine processes. They also need to find out how sweet coffee affects the human body.
