Smog Cough, Asthma or Chest Infection? Signs That Need a Doctor (Video)

Transcript

Breathing Through Smog

When November air turns hazy, many of us start coughing, but not every cough means the same thing. Let’s sort out what’s going on and when to act.

At a Glance

A quick look: a smog cough is dry and tickly, getting worse when you’re outside. Asthma flare-ups bring wheezing and a tight chest, especially at night. Chest infections usually come with fever and yellow or green mucus.

What a Smog Cough Feels Like

Fine particles in smog irritate the lining from your nose down to the lungs. You’ll notice a dry, scratchy cough, maybe a runny nose, sore throat and eyes that sting. The irritation spikes after a ride on a motorbike or a walk outside, then eases once you’re inside a closed room with a purifier running. There’s no fever, your appetite stays the same, and you feel annoyed rather than truly ill. That pattern, irritation that follows the air, is the key clue.

Smog, Asthma, Infection Side by Side

Real life blurs the lines. Smog can trigger an asthma flare, and a flare can turn into an infection. Look at the breathing signs: fever is rare with pure smog cough, but common with infection. Clear or white mucus points to irritation, while yellow, green or rusty sputum suggests infection. Wheezing and a tight chest are mild in smog, frequent at night in asthma, and occasional in infection. Finally, notice if you feel better indoors, a quick improvement hints at smog, while little change may mean something else.

When Acid Reflux Mimics a Cough

Stomach acid that climbs up the food pipe, especially after a late, heavy dinner, can irritate the throat and voice box. You may cough within an hour of eating, taste something sour or bitter, feel a burning behind the breastbone, and wake up hoarse. The winter habit of late-night meals and staying up late makes this more common during smog season. Simple checks: does the cough start after you eat or when you lie flat? If yes, reflux could be the culprit.

Using Your Inhaler in Smog Weeks

Smog weeks test your asthma or COPD plan. The biggest wins are small and practical. Keep taking your preventer inhaler, the brown, orange or purple one, exactly as prescribed, even if you feel fine. Carry your blue reliever inhaler with you at all times and check the expiration date. If you use a metered dose inhaler, attach a spacer; shake, take one puff into the spacer, then wait four seconds before the next. After a steroid preventer, rinse your mouth and spit to protect your throat.

Seasonal Swaps for Cleaner Breathing

Swap a few everyday items to protect your lungs. Replace cloth or surgical masks with a fitted N95 or KN95 when you’re outside; pinch the metal strip over the nose and if your glasses don’t fog, you’re sealed. Skip morning walks if the air-quality index is above 150, and stay inside completely when it tops 200. Use an electric heater instead of an angithi or gas heater in a closed room, and keep a window cracked open to let fresh air circulate. Finally, put away mosquito coils and incense, and opt for nets or plug-in repellents during the smog months.

When to Call a Doctor

If you experience any of these, seek care right away: sudden breathlessness while sitting, inability to finish a sentence, lips or fingertips turning blue or grey, the chest pulling in between the ribs, confusion, drowsiness, coughing up blood, chest pain, or an oxygen saturation reading of 92 % or lower at rest. Even if you’re not in emergency mode, see a doctor today for a reading of 93-94 %, a fever of 39 °C or higher, a fever that lasts more than three days, a reliever inhaler that stops working after less than four hours, or a new wheeze. These signs mean it’s time to stop guessing and get professional help.
