, as per a recent analysis.

Researchers have found five proteins that are directly associated with feelings of loneliness, which can lead to a variety of health problems.

Researchers arrived at this conclusion after examining proteins extracted from blood samples collected from numerous thousands of adult volunteers participating in the UK Biobank project.

Their research underscores the significance of social interaction in maintaining our well-being.

Research previously conducted has established that both social isolation and loneliness are associated with lower overall wellbeing and a higher risk of early mortality.

The researchers analyzed proteins in blood samples given by 42,000 adults between the ages of 40 and 69.

This enabled researchers to identify the proteins present in greater abundance among socially isolated or lonely individuals, and examine how these proteins are related to poorer health outcomes.

Research found five proteins whose increased levels are linked to loneliness - some of which have previously been associated with an elevated risk of cardiovascular disease, high cholesterol, the development of insulin resistance and premature mortality.

Dr. Chun Shen, one of the study's authors, stated: ‘We know that social isolation and loneliness result in poorer health, but we've never understood the underlying reasons leading to this connection.

Our research has identified several proteins which seem to have a crucial part in this connection, with specific proteins showing enhanced levels directly resulting from feelings of loneliness.

Professor Barbara Sahakian, of the Department of Psychiatry at the University of Cambridge, noted: “These findings emphasize the significance of social interaction in maintaining good health. Increasingly, people of all ages are expressing feelings of loneliness.”

The World Health Organization has called social isolation and loneliness a major "global public health concern".

‘We must identify effective strategies to address this escalating issue and maintain connections for individuals to preserve their well-being.’

The study's results were published in the Journal of Human Behavior.
