Functional medicine practitioner Dr Will Cole says modern diet, environmental exposures and chronic stress may disrupt cellular health and contribute to faster biological ageing. The article matters because it highlights modifiable lifestyle and environmental factors, while noting that symptoms such as fatigue and brain fog are non-specific and should not be self-diagnosed.

Cole identifies an unhealthy diet and prolonged eating periods, exposure to pesticides, PFAS, pathogens, mould and evening blue-enriched light, and chronic stress, trauma or social disconnection as the three main concerns. He argues these may create “cellular noise”, although effects vary by substance, dose and duration, and observational studies on spirituality and health cannot prove cause and effect.
