Sri Vijaya Puram, May 3: In a remarkable scientific insight that bridges ancient wisdom and modern biochemistry, internationally acclaimed environmental scientist Padma Shri Dr. Ajai Kumar Sonkar has revealed that trees release powerful bioactive compounds capable of enhancing human immunity, reducing stress, and potentially contributing to longevity.
Addressing researchers and environmental scholars, the renowned scientist stated that forests are not merely collections of trees but complex biochemical ecosystems that actively interact with the human body.
Trees Emit Protective Bioactive Molecules:
Dr. Sonkar explained that trees release volatile organic compounds known as phytoncides, natural defensive chemicals produced to protect plants from harmful microbes and insects. These compounds include alpha-pinene, beta-pinene, limonene, and other terpenes.
“The forest is not silent,” Padma Shri Dr. Ajai said. “It is chemically alive. Trees continuously emit protective molecules into the atmosphere. When humans breathe this forest air, these molecules influence our immune and nervous systems.”
The concept of phytoncides was first introduced in 1928 by Russian biochemist Boris Tokin, who identified these natural antimicrobial vapors released by plants.
Scientific Validation: Immune System Activation
International research has demonstrated measurable physiological effects of forest exposure. Japanese immunologist Qing Li at Nippon Medical School showed that spending time in forests significantly increases Natural Killer (NK) cell activity, immune cells responsible for destroying virus-infected and cancerous cells.
“This is not philosophy; this is immunology,” Dr. Sonkar further said. “Forest exposure increases anti-cancer proteins such as perforin and granzymes. The immune enhancement effect has been shown to last for several weeks.”
The Japanese practice of forest immersion, known as Shinrin-yoku, has now become a recognized preventive healthcare approach in multiple countries.
Reduction of Stress and Hormonal Balance
The internationally acclaimed scientist further explained that phytoncides help regulate stress physiology. Clinical observations reveal:
• Reduction in cortisol (stress hormone)
• Lower blood pressure
• Decreased sympathetic nervous system activity
• Increased parasympathetic “rest and recovery” response
“In modern cities, we inhale pollutants. In forests, we inhale protective biochemistry,” Dr. Ajai stated. “The difference is profound at the cellular level.”
Forests as Earth’s Immune Organs
Drawing from his extensive environmental microbiology research, Dr. Sonkar described forests as “planetary immune organs.”
According to him, forests continuously release antimicrobial aerosols, regulate atmospheric microbial balance, and create biochemical environments favorable to human health.
“Just as the human body has an immune system, the Earth has ecological immune systems,” the renowned scientist said. “Forests act as atmospheric disinfectants and physiological regulators.”
Longevity: Direct or Indirect?
While no single molecule has been proven to directly extend lifespan, epidemiological data show that populations living near green environments exhibit:
• Lower cardiovascular mortality
• Reduced incidence of depression
• Stronger immune resilience
• Improved overall life expectancy
“Longevity is multifactorial,” Padma Shri Dr. Ajai revealed. “But regular exposure to forest-derived bioactive compounds contributes significantly to systemic balance.”
Not Hormones, But Powerful Signaling Molecules
Clarifying a common misconception, Dr. Sonkar noted that phytoncides are not plant hormones but defensive secondary metabolites, primarily terpenes.
“However,” he added, “their interaction with human physiology is comparable to biological signaling molecules. They modulate immunity, inflammation, and neural responses.”
A Call for Urban Planning Reform
The internationally acclaimed scientist emphasized that modern urban planning must integrate dense green zones, not as decorative elements, but as public health infrastructure.
“Planting trees is not beautification,” Dr. Ajai concluded. “It is preventive medicine.”
Conclusion
Scientific evidence now supports what traditional cultures intuitively understood: forests heal. Through the release of phytoncides and other bioactive compounds, trees create an invisible shield that supports human immunity, reduces stress, and enhances physiological balance.
As Padma Shri Dr. Ajai Kumar Sonkar has revealed, forests are not passive landscapes, they are dynamic biochemical guardians of human health.
