Delhi On High Alert: Air Pollution Linked To Severe Brain Damage, Experts Issue Urgent Health Warning

Delhi's air pollution has reached hazardous levels. Experts warn that the toxic smog and fine particles may not only damage lungs but also harm the brain.

Delhi's air pollution has once again reached alarming levels, with the Air Quality Index (AQI) at 316 (in the "very poor" category) according to the Central Pollution Control Board (CPCB). The current levels are 11.6 times higher than the World Health Organisation's safe limit for PM2.5, which was measured at 168 g/m. The sky is filled with smog and it is difficult to breathe and see.

Although the majority of the population is aware that the contaminated air is damaging the lungs and heart, not many are aware that it may also harm the brain. Being exposed to hazardous air is not only followed by coughing or shortness of breath, but can also gradually influence memory, mood, and even mental health.

Air Pollution Affects the Brain

The brain requires an uninterrupted amount of oxygen. The harmful airborne particles such as PM2.5 and PM10 are able to find their way into the bloodstream when they reach the lungs and are transported to the brain when the air we breathe is unhealthy. In the long run, it may cause inflammation and oxidative stress which are damaging to brain cells.

Research has revealed that individuals residing in urban areas that are polluted exhibit a high probability of developing memory impairments, anxiety, and depression. The prolonged exposure in children can retard the growth of the brain, which has an impact on learning and attention. In the case of the aged, the risk of dementia and Alzheimer's disease may also work to their disadvantage.

Air Pollution: Symptoms to Watch Out For

The majority of consequences of air pollution on the brain emerge gradually. These may not be obvious initially, but with time, they may become severe. Some early signs include:

1. Frequent headaches
2. Difficulty in concentrating or remembering things
3. Mood swings or irritability
4. Unusual tiredness
5. Difficulty sleeping

Who Is at Greater Risk?

The children, the elderly, as well as people with pre-existing health conditions are at greater risk. The mental development of kids is still developing and thus polluted air can impact on the development of the kid over a long period. Ageing can lead to a greater rate at which cognitive functioning is impaired. Individuals working out in the open or those who are on a daily basis are also considered at higher risk because of constant exposure.

How To Stay Safe During Air Pollution?

Here are some of the important safety precautions which you must take:

1. Monitor air quality: There are apps to monitor air quality, and outdoor exercise should be restricted during periods of heavy pollution.
2. Wear N95 masks when going out: Ordinary cloth or surgical masks do not block pollutants. Use N95 or N99 mask for better protection.
3. Stay hydrated, eat well: Eating a diet rich in fruits/ vegetables and omega-3 fatty acids helps keep the blood vessels and the brain healthy.
4. Use air purifiers at home: A decent air cleaner would have the capacity to eliminate indoor air contaminant such as fine dusts more so in the bedrooms and living rooms.
5. On smoggy days, keep the windows closed: Trying to avoid the entry of polluted air into your house, primarily when air quality index (AQI) is high.

With proper vigilance and simple safety precautions, you can ensure that you are not exposed to any of its silent perils and keep your families and friends safe.
