Loneliness is a global health priority, according to the World Health Organisation (WHO). This may come as a surprise to some, but the evidence is clear: people of all ages, in every corner of the world, are grappling with feelings of isolation. The scale of the issue is alarming, with one in four older adults experiencing social isolation and between 5-15% of adolescents feeling lonely. This is not just a problem in developed countries; low and middle-income nations are facing similar challenges.
The health impact of loneliness is significant. The Centre for Disease Control and Prevention states that people lacking social connections are at higher risk of premature death, heart disease, stroke, anxiety, depression, and dementia. Loneliness among heart failure patients increases the risk of death by four times, the risk of hospitalisation by 68%, and the risk of emergency department visits by 57%. The impact on mental health is particularly profound, with an increased risk of suicide among those who feel isolated. Loneliness increases mortality by 30%, which is the same or greater than smoking 15 cigarettes a day or mild to moderate obesity.
The consequences of loneliness extend beyond individual health to impact social health as well. Communities and societies as a whole suffer when social bonds weaken. Research indicates that strong social connections are essential for safety, prosperity, and effective governance.
Finding solutions for social isolation is crucial. The WHO is currently analysing evidence to identify the most effective strategies to combat loneliness. From national policies to individual interventions, there are steps we can take to create a more connected world. Practical tips include reaching out to loved ones, joining clubs or groups, volunteering, engaging in online communities, practicing self-compassion, developing hobbies, taking care of physical health, practicing mindfulness and meditation, and seeking professional help if needed.
Taking action against social isolation requires a multifaceted approach. It involves creating supportive communities, promoting mental health awareness, and encouraging open conversations about isolation. By recognising loneliness as a global health priority, we can work together to build a healthier, happier, and more connected world. The WHO’s declaration is a call to action for all of us to play a role in addressing this silent epidemic.
