Researchers at Harvard University have highlighted the health dangers of chronic loneliness. Their study, published in the journal eClinicalMedicinedemonstrates a 56% increase in the risk of stroke in people who constantly feel alone, explains The Sun. This work adds to an already long list linking loneliness to other pathologies such as heart disease, depression, dementia and diabetes.
The study, however, makes an important distinction. While chronic loneliness is harmful, a temporary feeling of loneliness does not present the same risks. Researchers also differentiate loneliness from social isolation, which is characterized by a lack of physical contact. Loneliness is a state of mind that can exist even when surrounded by people.
Chronic loneliness, a factor of stress and inflammation
How does loneliness affect our health? Several mechanisms are at work. Feeling alone is a major source of stress. However, chronic stress causes the release of cortisol, a hormone with harmful effects on the body.. Cortisol can in particular increase blood pressure and weaken the immune system.
Additionally, chronic loneliness is associated with a chronic low-grade inflammatory state. Inflammation, when acute, is a beneficial reaction of the body to an attack. But when it becomes chronic, it can damage blood vessels and promote the onset of cardiovascular diseases.
Combating loneliness: a public health issue
Faced with this alarming observation, researchers insist on
the need to take into account loneliness as a major public health issue. They recommend repeated assessments of loneliness in people at risk, to identify those requiring specific support.
Fighting against loneliness is not just an individual matter. Collective measures can also be taken to promote social bonds. These may include initiatives encouraging participation in group activities or the creation of spaces that encourage meetings.
Break isolation and reconnect with social connections
Fortunately, loneliness is not inevitable. Many solutions exist to break isolation and reconnect with social ties. Talking about your feelings to a friend, family member or healthcare professional is an important first step. Joining a club or association allows you to share interests and build relationships.
Even simple everyday actions can make a difference. Going to busy places, having a coffee on a terrace or walking in a park are all opportunities to make informal contacts. The important thing is to get out of the house and reach out to others.
