Increase in Stroke Cases Due to Air Pollution and Heat

For the first time, air pollution has been identified as a cause of brain strokes. According to a study published recently, the number of stroke cases and related deaths around the world has significantly increased. Factors like air pollution, rising temperatures, high blood pressure, and physical inactivity are considered responsible for this rise.

Stroke cases have risen by 70% compared to 1990.

According to the study, the number of people experiencing strokes worldwide increased to 119 million (1.19 crore) by 2021, compared to 1990 when there were 70% fewer cases. Furthermore, the number of stroke-related deaths globally increased to 7.3 million by 2021, a 44% rise compared to 1990. The risk of stroke has also escalated after the COVID-19 pandemic, with the heart and neurological systems becoming more vulnerable.

Key Findings:

• Stroke cases have increased by 70% since 1990.
• 44% increase in deaths due to stroke over the last 34 years.

Poor Diet and Air Pollution: Research also highlights that poor nutrition and air pollution are leading contributors to the global rise in stroke cases. These conditions are said to be responsible for over 40% of all stroke-related deaths worldwide. However, it has also been found that 30% of stroke survivors improved their health through proper dietary changes.

Air Pollution as a Major Factor: The study conducted by the Global Burden of Disease, Injuries, and Risk Factors team (GBD) indicates that particulate matter (PM) air pollution is one of the leading causes of strokes, especially due to its effects on the brain's blood vessels. Exposure to this type of pollution has been shown to increase the likelihood of strokes worldwide.
