When AQI Is Orange (101–150): Should You Exercise Outside?

On many dashboards, orange corresponds to AQI 101–150 — “Unhealthy for Sensitive Groups.” That does not mean everyone must stay inside, but it does mean you should adjust intensity and duration.

Who should be cautious

• Children and teenagers
• Older adults
• People with asthma, COPD, or heart disease
• Anyone recovering from respiratory illness

Practical workout rules

1. Sensitive groups: move exercise indoors or choose a very light walk.
2. Healthy adults: shorten hard sessions; avoid midday if ozone is also elevated.
3. Check the hourly forecast — if AQI is falling, train in the cleaner window.
4. Stay away from busy roads where tailpipe pollution is highest.
5. Stop if you cough, wheeze, or feel unusually short of breath.

When AQI pushes into red (151+) or purple, outdoor workouts are best postponed for everyone. Your tracker is a planning tool — pair it with how your body feels.
