Air pollution-related headache symptoms tend to be similar to a persons typical headache.
AQI values span from 0 to 500, with higher numbers representing higher levels of pollution.
Values at or below 100 are considered safe or satisfactory.

Those who are more sensitive to air quality may notice symptoms at slightly lower AQIs, she said.
If the AQI is greater than 100, sensitive groups should keep medicine handy in case of symptoms.
Its important to heed weather alerts about unhealthy air quality, no matter your health history.
On bad AQI days, avoid long or intense outdoor activities and consider moving activities indoors.
