Pollution levels in Delhi-NCR have risen significantly, causing growing concern among residents. Many people are currently troubled by symptoms like cough, cold, and allergies. Although antibiotics are being used, excessive intake can be harmful. While most people think pollution mainly affects the lungs, it also increases the risk of brain stroke, according to medical experts.
How Pollution Affects the Brain and Stroke Risk
Dr. Khushboo Goyal, Consultant and Head of Stroke Care Program and Neurology at Manipal Hospital, Delhi, explains that air pollution can increase the likelihood of stroke. Fine particles such as PM 2.5 can enter deep into the lungs through breathing and then enter the bloodstream, posing a threat to brain health.
These tiny particles can also reach the brain through the nose. Once in the body, they cause inflammation and oxidative stress, which may damage the blood-brain barrier and the inner lining of blood vessels that supply the brain. This damage raises susceptibility to stroke.
Exposure to pollution leads to narrowing of blood vessels and fluctuating blood pressure. Both conditions increase the risk of ischemic stroke, caused by interrupted blood flow, and hemorrhagic stroke, caused by bleeding in the brain.
Recognizing Stroke Symptoms and Protection Tips
It is important to identify stroke symptoms early to seek timely treatment. Warning signs include sudden weakness or numbness on one side of the body, trouble speaking or understanding speech, facial drooping on one side, loss of balance, or severe headache without explanation. Immediate medical help is critical to reduce stroke damage.
Preventive measures include avoiding polluted air, especially during poor air quality days. Using air purifiers or proper air filtration indoors can help maintain cleaner air. It is also advisable to avoid smoking and manage stress, get regular exercise, and maintain quality sleep. Controlling blood pressure is another vital step.
Dr. Khushboo Goyal highlighted the connection between pollution and stroke risk, emphasizing that pollution control and health monitoring are essential for brain safety. People living in Delhi-NCR and other affected areas should be vigilant and take protective actions to reduce their risk.
Pollution’s impact on health extends beyond respiratory issues, and recognizing its role in stroke can prompt better public health responses. Although managing pollution levels remains complex, individuals can follow advised precautions to safeguard their health and reduce stroke incidents.
