Cardiologist: Heart Reveals Biological Age Long Before Skin

Post by : Saif Nasser

Ageing is universal, yet public perception often reduces it to surface changes like wrinkles or greying hair. Dr Sanjay Bhojraj, a cardiologist with two decades of practice, argues that this narrow view overlooks internal decline—most notably within the heart.

In a recent video address, Dr Bhojraj outlined three common misconceptions about ageing and stressed that modifiable behaviours play a decisive role. His aim: to shift attention from cosmetic ageing to preserving internal function and long-term health.

He asserts the heart is a more accurate gauge of biological age than outward appearance. Individuals who look youthful externally can nonetheless harbour advanced cardiovascular ageing, elevating risks of heart disease, fatigue and reduced physical capacity.

Dr Bhojraj noted that daily routines often harm cardiovascular health without obvious signs. Practices regarded as convenient or normal—insufficient sleep, prolonged sitting, reliance on processed foods, and physical inactivity—can accelerate cellular and vascular wear.

According to him, ageing is cumulative rather than abrupt: it develops incrementally through daily choices rather than beginning at a fixed calendar age. Early adoption of heart-supportive habits offers stronger protection, though improvements remain possible later in life.

Symptoms that prompt attention—pain, weakness or persistent tiredness—often appear after internal deterioration has progressed. The heart’s decline can compromise circulation, reduce cerebral energy and diminish muscular vitality, illustrating why cardiovascular condition precedes visible ageing.

Dr Bhojraj summarised the conclusion succinctly: the heart can indicate biological age much earlier than external features.

Complementing these observations, Dr Jeremy London recommended practical measures to enhance lifespan and cardiac resilience. His guidance centres on accessible lifestyle changes rather than costly interventions.

Key recommendations include consistent physical activity, prioritising whole and minimally processed foods, maintaining restorative sleep, and fostering social engagement. He also cited evidence for heat-based therapies—such as sauna use—to improve circulation and promote relaxation.

Exercise need not be strenuous to be beneficial; a daily 30-minute walk confers meaningful cardiovascular advantages. Nutritional advice emphasises predominance of natural foods while allowing occasional indulgences, rather than extreme restriction.

Sleep plays a reparative role: inadequate or poor-quality rest undermines recovery processes and may hasten biological ageing.

Social bonds also carry measurable health benefits. Emotional support and regular interaction reduce stress load, a known contributor to cardiovascular disease.

Both clinicians emphasised that healthy ageing is achievable without exclusive reliance on wealth or pharmaceuticals. Rather, it depends on consistent, modest behavioural adjustments that are widely accessible.

Initiating these habits earlier maximises benefit, yet evidence indicates physiological gains can occur even when lifestyle changes begin later in life.

At its core, the message reframes ageing as an internal physiological process. Maintaining cardiac integrity is central to preserving functional youthfulness across organ systems.

The guidance is timely as many populations adopt faster-paced lifestyles, increase consumption of convenience foods, and extend sedentary screen time—factors that elevate risks for diabetes, hypertension and cardiac disease.

Individual responsibility for health is emphasised: small, steady choices—opting to walk, choosing water over sugary beverages, prioritising sleep and managing stress—accumulate into significant quality-of-life improvements.

For clinicians and the public alike, the take-away is clear: monitoring and supporting heart health offers a practical pathway to slow biological ageing and reduce chronic disease burden.

Adopting simple, evidence-based habits can thus protect cardiovascular function and contribute to longer, healthier lives.
