Loneliness and the Science Behind It

Loneliness is a pressing issue in many parts of the world today, and Canada is no exception.  It also doesn’t discriminate by age, as loneliness can be felt by anyone. Last month’s post discussed ways to avoid loneliness and depression in aging; this month, the focus is on the science behind loneliness.

According to a 2019 survey by Statistics Canada, almost one in five Canadians reported feeling lonely most days. With loneliness rising , it’s important to understand the science around it and the impacts on our overall health and well-being. In this blog post, we’ll take a look at the recent studies and surveys in Canada that have shed light on loneliness and its effects.

The Impact on Mental and Physical Health

It’s no secret that being alone too long can have negative impacts on both mental and physical health. According to a study published in the Canadian Medical Association Journal, individuals who reported feeling lonely were more likely to report poorer mental health, including elevated levels of depression and anxiety. Additionally, the study found loneliness was linked to higher inflammation, stroke & heart attack risk. It is also associated with functional impairment and dementia. This goes to show that loneliness can have a profound impact on both physical and mental wellbeing.

An analysis of 70 studies involving 3.5 million individuals found that loneliness was a contributing factor in an increased mortality rate of 26%.  The effect is comparable to other mortality risk factors such as obesity and smoking.  

Older Adults and Isolation

Loneliness is an especially pressing issue in Canada’s older adult population. According to a survey conducted by Statistics Canada, almost one-third of seniors reported feeling lonely most days, with female seniors being the most likely to report feeling lonely. This suggests that it’s particularly prevalent among this demographic.   

In fact, in the United Kingdom, a study shows that older adults who are lonely seek socialization by visiting their doctor.  More than 75% of general practitioners reported seeing between 1 and 5 patients a day who visited because of loneliness.  In fact, doctors are now “prescribing” socialization as an intervention for loneliness.

How Technology Can Help

People, including older adults, are recognizing that technology can be a powerful tool in the fight against loneliness. According to a 2019 survey by AGE-WELL, over 70% of older adults over the age of 65 are confident in using current technology – an encouraging number since there are many online platforms and apps that allow users to connect with others and build meaningful relationships. Additionally, virtual reality technology can help older adults interact with the world. Finally, artificial intelligence and robotics can provide companionship and help older adults lead fuller lives. Japan is an example of a country experimenting the use of AI and robotics for their senior population.

Loneliness is a widespread issue in Canada and can have serious consequences on both mental and physical health. Recent studies and surveys shed light on isolation in older adults and the potential of technology to help. Going forward, it’s important to continue to invest in research and resources that are aimed at tackling loneliness and improving the overall well being of Canadians.
