Research reveals that a mother's exposure to air pollution during pregnancy could significantly increases her child's risk of developing asthma, suggesting that our respiratory health journey begins before we take our first breath. 

The study conducted in China tracked mothers and their children from 2015-2018, analyzing exposure to various pollutants throughout different stages of pregnancy.

• PM2.5 exposure during the second trimester is strongly linked to childhood asthma development
• PM10 exposure in the third trimester is similarly associated with increased asthma risk
• Sulfur dioxide exposure throughout pregnancy correlates with higher asthma rates
• Nitrogen dioxide shows complex effects, with first trimester exposure increasing risk
• Findings suggest preventative health measures may need to begin nine months earlier
• Results highlight the need for stronger environmental regulations to protect pregnant women
• Clean air represents a right for future generations that begins before birth
