Have you ever stepped outside, taken a deep breath, and instantly regretted it? Symptoms such as burning eyes, an itchy throat, and a heavy chest are signs of exposure to smog.
Smog has increasingly become a persistent issue rather than a seasonal concern, affecting daily life for many individuals. Activities such as morning walks are often postponed, children are frequently kept indoors, and even routine tasks can become more challenging. The health effects of smog might not be evident until serious issues arise, forcing people to deal with the consequences caused by long-term exposure to poor air quality.
To help you reclaim your well-being, we’ve created this Smog Survival Guide. It’s your toolkit for staying safe, filled with practical health tips, quick emergency actions, and essential insurance insights that provide a much-needed safety net. Let’s explore these before the everyday smog seriously affects you.
Smog is a term for a mixture of smoke and fog, a form of intense air pollution. It significantly reduces visibility by creating a hazy or foggy atmosphere. Smog is commonly found in densely populated cities with high levels of industrial and vehicular activity. This hazardous combination consists of fog, dust, and air pollutants such as nitrogen oxides, volatile organic compounds (VOCs), and other harmful substances. When these pollutants react with sunlight, they form a thick layer of ground-level ozone.
Did you know that even if you don’t feel unwell, the smog around you could be quietly damaging your health? It's a hidden threat that can affect many parts of your body, so it’s essential to stay aware and take precautions.
When it comes to smog, the impact on our health can be felt almost immediately. Some of the short-term effects you might experience include:
Smog can have profound and lasting impacts on our health. Here are some of the long-term effects you might not be aware of:
Smog contains fine particles known as PM2.5, which can infiltrate your lungs and enter your circulatory system. Once they enter the bloodstream, they trigger inflammation, leading to constricted blood vessels and a spike in blood pressure. The effects can be significant. They can lead to worsening COPD and asthma, and they may also raise the chance of having a heart attack. This 'invisible' threat is dangerous for vulnerable groups, including:
You cannot control the air outside, but you can control how you respond to it. Here are some practical ways to protect your health and breathe easier during smog season:
Stay safe by being aware of the air quality every day. Check websites or apps such as AQI India or Google Weather to find out the Air Quality Index (AQI) in your city.
| AQI Level | Category | What You Should Do |
|---|---|---|
| 0 - 50 | Good | Perfect air quality for all outdoor activities. |
| 51 - 100 | Moderate | Safe for most, but those with respiratory issues should stay alert. |
| 101 - 200 | Unhealthy | Limit outdoor activities. Everyone should start taking precautions. |
| 201 - 400 | Very Poor | Stop going outdoors and keep your indoor air clean by using air purifiers. |
| 400+ | Severe / Hazardous | Stay strictly indoors and use high-grade masks if travel is vital. |
When you need to leave the house or go outside, always wear a mask to protect yourself from harmful air pollutants, such as PM2.5 (Fine Particulate Matter). This pollutant is toxic and can harm your health if you inhale it. You can choose from three types of masks: N-rated, P-rated, and R-rated. The basic N95 mask filters up to 95% of PM2.5. The N99 mask filters up to 99%, and the N100 mask filters almost all (100%) air pollutants.
Did you know that smog creates free radicals? These radicals are unstable molecules that can be tough on your cells. But don’t worry, you can protect yourself. By loading up your plate with delicious antioxidants, you can neutralise that stress and keep your body feeling great. Some of them include:
Smog affects those already battling health issues the most. If you or a loved one has a history of heart disease, stroke, or respiratory problems, proactive care can be your greatest asset.
Planting trees is one of the most sustainable ways to combat air pollution. Trees play a crucial role in cleaning the air by capturing delicate particulate matter and neutralising harmful gases. A healthy tree can absorb several kilograms of carbon, helping significantly slow global warming. Expanding our home with green cover is the most effective way to improve local air quality and restore the natural balance of our environment.
Smog-related symptoms can develop rapidly. It's essential to monitor your body's reaction to poor air quality. Seek medical attention if you experience any of the following symptoms:
Did you know your health insurance might cover illnesses caused by smog? Many people are surprised to find that their plan can help with pollution-related health issues. It’s essential to learn how your coverage can support your health despite environmental challenges.
Specific insurance policies even extend their coverage to include respiratory problems linked to air pollution, particularly when these conditions result in hospitalisation. This means that if you find yourself battling health issues due to poor air quality, you may have some financial protection in place. Consider Care Health Insurance when looking for health insurance. It's a solid choice that offers comprehensive coverage at affordable premiums.

We can’t control the air outside, but we can control how we protect ourselves. Smog season can feel tough, but it doesn't have to disrupt your life. By making a few small changes, like checking the air quality index (AQI) before going out, wearing a proper mask, and eating healthy foods, you give your body a better chance to stay well.
Your health is your most important asset, so make sure you have your insurance and emergency plans ready just in case. Stay safe, look out for your family, and remember that even small steps can make a big difference in how you feel.

It depends on where you live. If you live in a city with heavy traffic and few green spaces, winter can be harsh due to pollution. But if you live in a sunny, crowded area, summer smog might be a problem, even if it is less visible.
For the best protection against PM2.5, wear certified respirators like N95, KN95, or FFP2 masks. These masks filter out at least 95% of tiny airborne particles and fit tightly to your face. Loose surgical or cloth masks are not effective for severe pollution.
Most standard health insurance plans cover respiratory issues like asthma and bronchitis worsened by smog, including hospitalisation, medications, and diagnostics. However, check your specific policy terms and conditions for exclusions, as many treatments may not be covered without a waiting period.
Elderly people can stay safe during smog season by minimising outdoor exposure, especially during peak pollution hours; wearing an N95 mask when outside; using air purifiers; and managing health conditions with a doctor.
