„The loneliness epidemic“ – a buzzword that has been coming up more and more in recent years. It seems to be an increasingly relevant topic, which is quite interesting and somewhat paradox, considering the parallel increase of innovative technology for creating connections between millions of people, no matter the time of day or location on the planet. However, something seems to be wrong. Reports show that around a third of the population of industrialized countries are affected by loneliness [1]. The group most affected by loneliness are young adults between 16 and 24 [5] and what is even more concerning – this number has been rising over the past few years [6]. The WHO has even declared loneliness a global public health concern in 2023 and launched and international commission to study the problem [2]. How can loneliness be such a prominent topic and increasing issue, when we are more connected than ever? This makes for an interesting research topic in which I will be asking the question of how interaction design can combat loneliness.
First of all, to better understand the topic of loneliness, the term has to be defined and differentiated from similar ones such as aloneness, solitude and social isolation, as these mean slightly different things. Aloneness and social isolation describe qualitative, objective measures in which an individual has no one around them. More subjective measures include solitude and loneliness. While solitude describes a feeling of voluntary aloneness, which is mostly a positive experience, loneliness is the opposite and describes a negative experience of the state of being alone [3]. There is no one definition of what loneliness is exactly, generally it is agreed that it can be described as the subjective discrepancy between an individual’s existing versus desired social relationships [1]. When looked at more closely, loneliness can be further categorized into three types. Social loneliness means the feeling of isolation from a social network or community. Simply put: the missing sense of belonging. Emotional loneliness describes the sense of lacking close, intimate, emotional connections. Finally, existential loneliness refers to a deeper inner feeling of being fundamentally alone in life. Further categorizations include transient, situational and chronic loneliness [3].
Since loneliness is for the most part a subjective feeling, it can be quite tricky to measure it for studies and observation. One of the most prominent attempts to measure loneliness is the UCLA loneliness scale which has bee revised several times and works like a relatively simple questionnaire [4].
Loneliness has a significant impact on mental and physical health. It can contribute, as well as cause depression. This vicious cycle has a high risk of increasing early mortality. With depression being the most common mental health issue, loneliness is a topic that should not be overlooked, since they are often intertwined [7]. Loneliness can also harm the body physically. Diabetes, autoimmune disorders, cardiovascular diseases, obesity, physiological aging, cancer, poor hearing and overall poor health have been found to be caused by loneliness [1,7]. Addressing loneliness could be an important step in the battle against the mental health crisis and improvement of physical wellbeing.
Besides mental and physical health loneliness can even impact the economy. Poorer work performance and lower educational attainment have been associated with loneliness and its accompanying symptoms. This is estimated to cost employers millions per year due to employee sickness, caring activity, productivity, and voluntary staff turnover [8].
It is clear that we need to better understand the loneliness epidemic in order to work on solutions that bring us together.
