Bengaluru, Feb 06 : Tech entrepreneur Bryan Johnson sparked a debate on air pollution in India after he abruptly left Zerodha co-founder Nikhil Kamath’s podcast midway, citing poor air quality. Johnson said the pollution caused a skin rash and left his “eyes and throat burning,” prompting his unexpected departure.
Johnson later took to X (formerly Twitter) to address the issue, stating, “Indians are justifiably outraged by the poor air quality they are exposed to daily.”He emphasized that the persistent pollution has “serious negative health effects”and called for urgent action.
Referencing a scientific study, Johnson shed light on the dangers of PM2.5 particles, a key component of urban air pollution linked to traffic and combustion engines. The study exposed mice to 12 weeks of low-level traffic-related PM2.5 pollutants, mimicking daily human exposure to city air pollution. The findings revealed alarming health implications, including liver inflammation, fibrosis, imbalances in blood fats, and gene dysregulation associated with cancer. Johnson explained that these microscopic particles, which can penetrate deep into the lungs and bloodstream, are among the most dangerous pollutants. “There is no safe level of exposure to air pollution,” Johnson stressed, adding that addressing this crisis could extend life expectancy in highly polluted regions like India more significantly than treating all cancers combined.
Johnson highlighted how air pollution affects the body beyond the respiratory system, causing widespread damage to organs such as the liver. He warned that PM2.5 particles, despite being imperceptible, have profound health consequences, making the issue a critical public health priority.
Offering solutions, Johnson shared practical tips to reduce individual exposure to air pollution. These included monitoring air quality levels, wearing an N95 mask, using higher-grade HVAC filters (MERV 13 or above), and activating air circulation functions in vehicles.
Johnson described the study’s findings as a “powerful reminder” of the severity of air pollution’s impact. He called for immediate measures to tackle the crisis, especially in India, where poor air quality has become a pressing concern for public health.
Johnson’s remarks follow growing international attention to India’s air pollution problem, with activists and experts urging stronger regulations to combat the crisis.
