When we hear environmental health, we often think of climate change, air pollution, sanitation, or WHO guidelines.
But while reading Siddha community medicine book called நோயில்லா நெறி (Noyillaa Neri), I found something unexpected.
It wasn’t just a book about preventing disease.
It was a book about preventing disease through the environment.
The text in a chapter discusses healthy village planning, clean water, sanitation, ventilation, housing, seasonal living, nutrition, maternal and child care, and even character formation as essential components of health.
It treats the environment not as a backdrop to health, but as one of its foundations.
One detail that fascinated me was the emphasis on house design, ensuring adequate sunlight and ventilation, ideas that remain relevant today in discussions about respiratory health and healthy buildings.
Another was its focus on community hygiene. Health wasn’t viewed as an individual’s responsibility alone. Clean surroundings, proper waste disposal, safe water, and well-planned communities were all considered part of disease prevention.
Today, modern public health tells us that where we live influences our risk of respiratory diseases, infectious diseases, heat-related illnesses, and even mental well-being.
Reading Noyilla Neri book, made me wonder if some traditional medical systems contain public health principles that deserve to be revisited and researched, not because they replace modern science, but because they invite meaningful conversations across time.
Perhaps one of the most striking Siddha ideas is this:
Prevention and cure are not two different branches of medicine. They are part of the same continuum.
Maybe that’s a perspective worth remembering.
If healthcare truly begins outside the hospital, should environmental health receive as much attention as diagnosis and treatment? What about other traditional medicines?
