Laughter heals: Social connection protects against loneliness!
What makes us laugh and why is it so important in everyday life? A current study carried out at the University Hospital Hamburg-Eppendorf and led by Prof. Dr. Led by André Hajek, together with other research, shows that real laughter not only improves mood, but also offers a protective function against loneliness and social isolation. In an online survey, around 5,000 adults between the ages of 18 and 74 in Germany were asked how often and in which situations they laugh. The results of this study are in the specialist magazine Health Science Reports published.
Respondents reported on their laughing habits and how these relate to their subjective feelings of loneliness and social connectedness. It was shown that frequent laughter in real social interactions leads to less loneliness. It looks different if the laughter only takes place in front of the screen. According to the study, digital laughter, such as when consuming media, does not have the same positive effect on our social relationships.
Real encounters count
The analysis illustrates the importance of personal encounters. Prof. Dr. Hajek emphasizes that laughter acts as a “social glue” – it strengthens social bonds. This is particularly relevant at a time when many people often feel isolated due to the digital world. While online social networks can have both positive and negative effects on our well-being, face-to-face contact is crucial to supporting our mental and physical health.
Surveys have shown that strong social connections reduce stress and improve psychological well-being. These factors should not be underestimated, especially in times of social withdrawal such as we have experienced in the past. Research suggests that social isolation significantly increases the risk of mental illnesses, such as depression and anxiety. In fact, people who live in isolation are three times more likely to develop depression.
Promote health through social connections
This makes it all the more important to actively promote social bonds. Regular communication with friends, joint activities and an open, honest basis of trust are practical recommendations that everyone can implement. In all phases of life, be it childhood, adolescence, adulthood or old age, social interactions are crucial for a happy life. Not only do they provide emotional support, but they can also support physical health.
In conclusion, laughter is more than just an expression of joy. It is a powerful way to combat loneliness and social isolation and promote mental health. The results of this study are not only a wake-up call for more real encounters, but also an impetus to question our own culture of laughter and perhaps spend time with friends more often to laugh together - this brings us closer and keeps us healthy.
