Quick answer: When the AQI is poor (201–300 on CPCB’s scale), most healthy adults can still take a gentle walk, but it’s smarter to keep it short, skip the early-morning peak, and move hard workouts indoors. People with asthma, heart or lung disease, older adults, children and pregnant women should do their exercise indoors on these days. Delhi’s air has been in the “poor” band since 21 October, and forecasts expect it to stay there for the next week.
Key takeaways
- CAQM put GRAP Stage 1 in force across Delhi-NCR on 21 October 2026 after the AQI crossed 200.
- Delhi’s AQI was 223 (“poor”) at 8 am on 23 October, as per CPCB data reported that day.
- On a poor-AQI day, walk easy, walk shorter, and do intervals or runs indoors.
- If you have asthma or heart trouble, keep all exercise indoors until the AQI drops.
In this article, you’ll learn:
- What “poor” AQI means and what GRAP Stage 1 changes
- Whether your morning walk is still okay
- Who should skip outdoor exercise completely
- A simple day-by-day rule you can follow this week
What Happened: GRAP Stage 1 and a “Poor” AQI
The Commission for Air Quality Management (CAQM) invoked Stage 1 of the Graded Response Action Plan (GRAP) across Delhi-NCR on Wednesday, 21 October, after Delhi’s average AQI went past 200. By Friday morning, CPCB data put the city at 223, still in the “poor” range, NewsDrum reported on 23 October. Jahangirpuri, Rohini and Punjabi Bagh were among the worst stations, all above 270.
The early warning system expects “poor” air through 24 October and similar conditions for the six days after that. Farm-fire smoke was expected to add to it in the coming days.
Stage 1 is mostly about pollution sources: construction dust, open burning, older and polluting vehicles. It doesn’t tell you what to do about exercise. That part is up to you.
What “AQI Is Poor” Actually Means
India’s AQI runs from 0 to 500. CPCB splits it into six bands, and the band tells you more than the exact number does.
| AQI | Band | What it means for a walk |
|---|---|---|
| 0–50 | Good | Walk, run, anything |
| 51–100 | Satisfactory | Fine for almost everyone |
| 101–200 | Moderate | Sensitive people take it easy |
| 201–300 | Poor | Short, easy walks; hard workouts indoors |
| 301–400 | Very poor | Exercise indoors |
| 401–500 | Severe | Indoors only, keep windows shut |
When the AQI is poor, CPCB’s guidance says most people may feel breathing discomfort on long exposure. The key word is “long”. A 20-minute easy walk is a very different dose from a 60-minute run, because when you push hard you breathe faster and deeper, and you pull more PM2.5 into your lungs.
You can check the live number for your nearest station on the CPCB AQI dashboard. City averages hide a lot. Your area might be 190 or 280.
Is a Morning Walk Still Okay When the AQI Is Poor?
For most healthy adults, a short, easy walk is fine. The trouble is that early morning is often when the air is at its worst in winter. Cold, still air sits low and traps smoke and dust close to the ground until the sun warms things up.
Here’s a simple rule for this week:
- AQI under 200 at your station: walk as usual.
- AQI 201–300 (poor): keep it to 20–30 minutes at an easy pace. Go later in the morning if you can. Save brisk intervals and runs for an indoor session.
- AQI above 300: skip the outdoor walk. Do it indoors.
Walk away from main roads where you can. A lane inside a colony or a park set back from traffic usually beats walking along an arterial road during rush hour.
The WHO links fine-particle pollution to heart and lung disease, which is why limiting how much you breathe in on bad days matters, even if you feel fine.
Who Should Skip Outdoor Exercise Right Now
Some people feel the effects at much lower levels. If you’re in one of these groups, move your exercise indoors while the AQI is poor:
- People with asthma, COPD or other lung problems
- Anyone with heart disease or high blood pressure that isn’t well controlled
- Adults over 65
- Children, especially for long outdoor sports sessions
- Pregnant women
Stop and rest if you notice chest tightness, unusual breathlessness, coughing that won’t settle, or dizziness. The NHS asthma page lists warning signs that need urgent help.
How to Keep Your Steps Up Indoors
You don’t have to lose a week of progress because of smog. Walking indoors counts the same for your step total and your calorie burn.
- Walk laps of your home or building corridor while on calls.
- Try a 30-minute indoor walking routine with marching, side steps and stair climbs.
- Use a treadmill if you have one, with windows closed.
- Add two short strength sessions this week. Squats, push-ups and rows need no outdoor air at all.
Frequently Asked Questions About Walking When the AQI Is Poor
Q: Is it safe to walk outside when the AQI is poor?
For most healthy adults, a short, easy walk is generally okay. Keep it under 30 minutes, avoid busy roads, and do intense workouts indoors.
Q: What time of day is the air usually better?
In winter, early morning and late night are often worse because cold air traps pollution near the ground. Late morning or afternoon is usually a little better, but check your local station.
Q: Does wearing a mask help while walking?
A well-fitted N95 filters fine particles better than cloth masks. It can feel harder to breathe in during brisk exercise, so slow your pace if you wear one.
Q: How long will Delhi’s AQI stay poor?
Forecasts issued on 23 October expected “poor” air through 24 October and similar conditions over the following six days. Check the CPCB dashboard daily.
The Bottom Line
The AQI is poor in Delhi-NCR, and it’s likely to stay that way for a while as winter sets in. That doesn’t mean you stop moving. Walk shorter and easier outdoors, push hard indoors, and keep everything inside if you have a heart or lung condition.
