Loneliness and social isolation may increase the risk of cardiovascular events, according to new research published in Nature.

With Australians losing 685,000 healthy life years to cardiovascular conditions in 2024 as per the latest report by the Australian Institute of Health & Wellness, researchers say it’s time to broaden the heart health conversation to include the influence of mental wellbeing and lifestyle as well as physical health.

The post-pandemic landscape has seen loneliness emerge as a public health crisis, with one in four Australians experiencing persistent loneliness.

This issue is particularly acute among young adults (18-24 years), a demographic that also faces widespread sleep challenges – with nearly three in four Australians reporting sleep difficulties, according to a recent Finder survey.

These issues collectively elevate the risks of cardiovascular events, high blood pressure, and even cognitive decline.

A Holistic Approach Needed

In recognition of Heart Health Awareness Month this February, Dr Ross Walker, Australia’s “leading” integrative cardiologist, is advocating for a broader view of heart health.

He emphasises that alongside medications and clinical treatments, nurturing meaningful relationships and prioritising quality sleep are equally important in maintaining a healthy heart.

Dr Walker emphasises the role of mitochondrial health powered by the endogenous antioxidant ubiquinol, found naturally in our bodies, which impacts our wellbeing from the age of 20-plus.
