Air quality alerts can interrupt a normal day with very little warning. School, work, commuting, exercise, errands, and outdoor family plans can all become harder when the air is unhealthy. Poor air quality can come from wildfire smoke, fine particle pollution, ozone, vehicle emissions, industrial pollution, or weather patterns that trap dirty air near the ground.
This guide explains what air quality alerts mean, who is at higher risk, and how families can reduce exposure to unhealthy air. AirNow explains the Air Quality Index, or AQI, as a color-coded system for reporting air pollution and related health concerns.
What Air Quality Alerts Mean for Your Health
Understanding AQI Colors and Warning Levels
The AQI helps individuals comprehend how clean or polluted the air is on a given day. A higher number means the air is worse and people should take more care before spending time outside. The colors make the warning easier to follow. Yellow means moderate air quality. Orange is unhealthy for sensitive groups. Red is unhealthy for everyone.
Purple means extremely unhealthy. Maroon means hazardous and is an emergency level. Code Purple is listed by the AirNow system when the AQI is between 201 and 300. In the Purple range, the risk of health effects for the general public is increasing. The AirNow system, local weather alerts, and city health updates should be checked before making any outdoor plans.
Common Symptoms During Poor Air Conditions
Unhealthy air can bother the eyes, nose, throat, and lungs. Some people feel symptoms quickly, especially if they are active outside. Common symptoms include coughing, wheezing, shortness of breath, chest tightness, headaches, fatigue, and asthma flare-ups.
CDC guidance says children, pregnant people, older adults, and people with asthma, COPD, heart disease, diabetes, or chronic kidney disease should be especially careful around wildfire smoke. Severe breathing trouble, chest pain, confusion, fainting, or symptoms that feel urgent should be treated as reasons to seek medical help right away.
Who Should Take Extra Precautions During Alerts
Children, Seniors, and People With Medical Conditions
Some people can be affected more quickly or more severely by unhealthy air. Children are one example because they breathe more air for their body size and often spend more time running or playing outside.
Older people and folks with lung and heart issues may need to decrease activity levels more than healthy people. Families may need to keep medications, inhalers, emergency contacts, and doctor instructions handy for days with bad air. This is important when conditions may suddenly worsen or persist for days with poor air quality.
Outdoor Workers, Athletes, and Commuters
During an alert, outdoor workers, athletes, runners, cyclists, delivery workers, construction workers, commuters, and others may suffer from extended exposure. Spending extended time outdoors leads to inhaling more polluted air. The CDC/NIOSH states that the use of NIOSH-approved respirators, such as N95 or P100, protects workers and the public from the particles of wildfire smoke when exposure to the outdoors is unavoidable.
During periods of high AQI, people should reduce strenuous outdoor activity, take more breaks indoors, move workouts indoors, and avoid outdoor activity altogether. Schools, camps, teams, and employers should move activities indoors or reschedule to a later time when alerts indicate an unhealthy level.
Simple Ways to Reduce Exposure to Unhealthy Air
Keep Indoor Air Cleaner at Home
During unhealthy or very unhealthy air quality warnings, it’s usually best to remain indoors. Close any open airways by keeping doors and windows shut. If you have it, turn your air conditioning to recirculate. If you have your air conditioning set to recirculate, it’s best to avoid activities that worsen indoor air quality, such as vacuuming without a HEPA filter, burning candles, frying food, and smoking.
CDC advises creating a cleaner room by closing it off from outdoor smoke and using a portable air cleaner or high-efficiency filter when available. If the home becomes too hot without air conditioning, a cleaner indoor public space may be safer because extreme heat can also become dangerous.
Protect Yourself When You Must Go Outside
Some trips can’t really wait. You have to go to work, make medical visits, go to the grocery store, pick up your kids from school, and run urgent errands. Try to minimize the amount of time you spend in public. Walking is better than running, and try to plan your route to avoid busy intersections or obstacles.
The best thing you can do if you have to spend time outdoors during these events is to wear an N95 or KN95 mask that fits well. Just recently, Philadelphia had a Code Purple due to Canadian wildfire smoke. A local news outlet reported that health officials were advising people to stay indoors even more due to heightened health dangers.
Conclusion
Air quality alerts are issued to the public to inform them of potential health risks from air pollution, with particular attention to smoke from wildfires, ozone, and particulate matter. While everyone suffers from poor air quality, children, the elderly, pregnant people, those with heart and lung issues, outdoor workers, and athletes should take more precautions.
Keep updated on the AQI, avoid going outside, improve indoor air quality, limit activity to indoors, and use a good-quality respirator when necessary. There are many preparations families can make to improve air quality, reduce air pollution, and stay safer until conditions improve.
