Habits and mood are related to each other

The experiment involved 79 adult residents of the United States aged 18 to 80. For 70 days, they reported on their well-being and activities every day: how much they slept, walked, moved, what they ate, how much coffee or alcohol they drank, whether they socialized with people, engaged in hobbies, or watched movies. To assess their mood, the participants answered questions from a special scale that shows how pronounced positive or negative emotions are on a particular day.

Modern statistical methods were used to analyze the data. The experts tried to understand how the events of one day affect the next, and how it all relates to mood. They created a separate map of connections for each participant. For example, for one person, walking had a significant impact on their mood and appetite, while for another person, it had almost no effect.

The results revealed several important insights. On average, those who moved more often spent more time outdoors and ate more vegetables and fruits. Within a single day, people were more likely to consume alcohol during social interactions, and outdoor activities were associated with increased activity and healthier eating habits.

Another pattern is that habits make you keep doing something. For example, if a person spent more time on a hobby on one day, they were more likely to return to it the next day. Almost all habits behaved this way, except for sleep duration, where no such pattern was found.

Mood was also closely related to daily activities. On days when people felt better, they were more likely to socialize, go for walks, relax, sleep longer, eat fruits and vegetables, and engage in their favorite activities. And when people’s mood was bad, they were more likely to complain about poor sleep and spend less time on hobbies and watching movies.

But the most important thing is that these connections were different for everyone. For one person, physical activity was closely linked to outdoor activities, while for another person, there was no such pattern. For some people, socializing had a significant impact on their mood, while for others, it had little effect. This suggests that there is no one-size-fits-all approach to creating habits, as they may work differently or not at all for everyone.

The authors of the study emphasize that the findings are still preliminary. The study involved a small group of people, and the data was self-reported, which means that there may have been inaccuracies in the participants’ recall. However, the idea itself is important. The goal is to help individuals make lifestyle changes by considering their unique characteristics. Instead of providing general advice such as “exercise more and eat a healthy diet,” future studies may focus on providing personalized recommendations based on how individuals’ habits and emotions are interconnected.
