Did you run around outside on a hot summer day and suddenly your lungs feel like they're burning?
You may be too tired.
Or your lungs may react to contaminants and chemicals in the air.
Understanding air pollution can help you avoid it and think about how to make it cleaner.
Air pollution usually refers to two substances: ozone and fine particulate matter, which are harmful to human beings.
Fine particles, or tiny dust-like substances, are mainly produced by burning fossil fuels, such as gasoline in cars and coal in power plants.
Fine particulate matter is much smaller than the dust you find after not cleaning the room for a while.
Small size, which is problematic for our health, because it can precipitate deep in our lungs, making it difficult for us to breathe.
Ozone is produced due to chemical reactions.
Sunlight reacts chemically with the gas produced by burning fossil fuels to form the groundlevel ozone.
When the ozone in the atmosphere is high, it helps to protect life on the ground from harmful radiation from the sun.
This radiation can cause problems such as skin cancer.
When ozone approaches the Earth, it becomes a problem.
When Ozone enters our lungs, it is harmful to our health.
As the child's body and lungs are developing, they are at a higher risk of destruction of ozone and particulate matter, especially in children with asthma.
"Children tend to have a higher frequency of breathing
Breathe in and out more quickly than adults]
"Janet Phoenix of the Clean Air Partner Group says it teaches people about air pollution in the Washington area.
"So they are more exposed to any chemical particles that may be present in the air.
Some of the worst air
The day of quality is actually the most beautiful day.
On hot and sunny days without wind, the air will not move around, and pollutants will accumulate.
"The air is in poor circulation, and heat and light help to bake chemicals into the air," Phoenix said . ".
Rain helps to wash bad things out of the air, so the worst time out there is not rain for a while.
"It's like if you don't take a shower for a few days, you know what's going to happen," said Ross salavich, professor of atmospheric and Marine Studies at the University of Maryland . ".
"The rain is clean like a shower.
"To help you know when it's safe to be outside, a few days have been assigned color codes that correspond to numbers that represent how many harmful substances are in the air.
When the amount of ozone and particulate matter reaches unsafe levels, the day will be marked as orange code, red code, and the worst days marked as Purple code.
"When we have air
"Red or purple, or even orange quality alerts are the days to stay indoors and play video games," Salawitch said . ".
Phoenix says the worst time of the air quality day is when people walk back and forth from school and work.
"If you can wait until later in the day to do something like this [outdoor]
"Sports, especially in the red or orange areas, you will have a better time," she said . ". The good news?
According to Salawitch, air quality in Washington is improving due to stricter pollution regulations.
There hasn't been a red code day in the area for the last three summers.
The last Purple code is in 2006.
But even a short period of exposure to bad air quality can have a negative impact on your body.
That's why local residents should limit activity to increase air pollution, Phoenix said.
Try to encourage your family to walk to the pool or library.
Don't let your parents drive you after school, but take the bus instead.
Keeping family cars off the road means reducing air pollution.
Not just for your neighbors.
"What do you do in part D? C.
"It will affect your neighbors," said Phoenix . " Local residents are becoming more aware of this, he added.
"I think it's great that people are really trying. ”
