Southeast Asian countries like Thailand, Vietnam, Malaysia, and the Philippines have been experiencing record-breaking heat. These recent extreme temperatures have led to heat stress-related consequences like agricultural disruptions and power outages. In South Vietnam, whole rice fields dried up. Additionally, schools were suspended in the Philippines after temperatures rose above 42 degrees Celsius. Meanwhile, across Thailand, temperatures soared and broke records continuously for 13 months!

Further, research also highlighted concerning trends, including the emergence of respiratory and cardiovascular issues from e-cigarette use. A recently published cohort study from Hebei province, China, provides pivotal evidence linking chronic obstructive pulmonary disease (COPD) and vaping. The study tracked over 10,000 healthy participants without prior respiratory conditions from 2015 to 2020. At the end of the study, the researchers found a 28% increase in the risk of respiratory symptoms. It also found a 8% increase in the risk of COPD in e-cigarette users. Additionally, dual users who use both e-cigarettes and conventional cigarettes had a 41% and 18% increased risk in respiratory symptoms and COPD risks. These findings contribute to the growing body of evidence cautioning against the use of e-cigarettes and highlight the need for healthcare professionals and policymakers to reassess the role of vaping in smoking cessation strategies.

Complementing these findings, a new study in China proved that improving air quality significantly declined suicide rates. By meticulously analysing data over several years, researchers found a clear, inverse relationship between air quality improvements and suicide incidences. This statistical study estimates that PM2.5 reductions under China’s Air Pollution Action Plan prevented 13,000–79,000 (95% confidence interval) suicides over 2013–2017. Therefore, environmental policies and concerted efforts to cleanse the air can yield significant mental health benefits.

These studies serve as a reminder of the urgent need for countries across Asia and the globe to address air pollution as a multifaceted health hazard and emphasise the importance of considering environmental risk factors, including air pollution, in understanding and addressing the causes of psychiatric disorders.
