Nowadays we are exposed to an infinite number of pollutants.The exposure to such high levels of pollution have led to several health threats. In that case The Air Quality Index comes to rescue. It tells us about the quality of air of a particular place.
So in this article we will discuss what does an Air Quality Index of 159 mean, which groups are more susceptible to such high levels of pollution, and what is the importance of AQI. And finally how we can protect ourselves from the exposure to harmful pollutants.
What does an Air Quality Index of 159 mean?
The AQI value of 159 indicates the unhealthy pollution levels in the ambient air. The values from 151-200 indicate that both healthy people and sensitive groups may begin to feel the effects of unhealthy AQI. The unhealthy values of 151-200 are represented by the Red color in the Air Quality Index.
What does the Air Quality Index look like?
Below is the table showing the Air Quality Index:
|Air Quality Index||Levels||Color coding|
|101-150||Unhealthy For Sensitive Groups||Orange|
Who is at a higher risk?
With the air quality reaching unhealthy levels everyone must limit their exposure to the ambient air. Healthy people may start to feel the symptoms of bad AQI . Sensitive groups including; people with preexisting health conditions like:
- Heart disease (hypertension, heart failure)
- Lung disease
- Elderly people (65 years and above) are at a higher risk of exposure.
To avoid exposure, both healthy and sensitive groups should avoid outdoor exertion for a long time.
How can we protect ourselves from exposure to unhealthy AQI levels?
Below are some of the measures you can adopt to protect yourself from unhealthy AQI level of 159
Schedule your exercise according to the AQI levels
You can exercise indoors especially if you live in urban areas. You can stay indoors; especially on low air quality days. If you suffer from asthma, diabetes or other health conditions, consult with your doctor about your exercise routine.
If you want to go outside for physical activities the you may refer to the chart below:
|Air Quality Index||Short duration (15 mins )||Duration for Prolonged exertion (1 hour)||Duration for strenuous activities( 2-4+ hrs)||Duration for scheduled activities like sports events|
|151-200 Unhealthy||Short duration physical activities can be done but watch for symptoms like coughing and shortness of breath||Mild exercise can be done but watch for symptoms like coughing and shortness of breath||Avoid doing strenuous exercises with frequent rest periods||All the outdoor activities should be reschedule or relocation is ideal in this situation|
Keep yourself updated with the air pollution levels
You can keep a check on the air quality index of your area to get insight about the pollution levels. There are certain websites designed for this purpose such as the Environmental Protection Agency. These sites can be accessed anytime of the day. You can also contact the local hospitals to get an insight. The local news and radio channels also notify you about the Air Quality Index of your area.
Avoid going to high-pollution areas
Pollution levels are the highest near the roadways especially within 1/4 mile of a road. Highly congested urban areas and smoking areas should also be avoided.
Don’t smoke cigarettes
Smoking cigarettes can release upto 7,000 chemicals out of which about 70 of them are carcinogenic. The tobacco smoke also affects the efficiency of your air filters. Some of the major chemicals include; benzene, acrolein, formaldehyde etc. These toxic chemicals have several health hazards including lung cancer.
Try to use less energy at your home
Electricity generation creates air pollution. By reducing your energy usage you can actually help improve the air quality.
Do not burn wood or trash
Wood and trash burning contributes to particle pollution; particularly soot. Encourage your neighbours, friends and family members to do the same.
Install Air Purifiers to keep your home safe
Air purifiers are devices which circulate the air through a set of filters and capture the contaminants like; microscopic particles such as dust, allergens, molds, spores, bacteria, etc, that are floating around. Hence purifies the air around you.

Run air conditioners
When the AQI hits an unhealthy level of pollution, run your air conditioners in continuous cycles. This creates a cyclic airflow and does not permit any particulates to enter the house.
You can find the links to some air conditioners in the links below:
|Air conditioners||Why i recommend it|
|AmazonBasics Window-Mounted Air Conditioner||Remote controlled AC with dehumidifier |

Install HVAC systems
The HVAC system works efficiently towards filtering airborne contaminants. If you have a central heating, ventilation and air conditioning system (HVAC) at home, set the fan to the “on” position rather than auto, especially when you have visitors. This helps in continuous circulation of air. The filter should be upgraded on a timely basis in order to maintain its efficiency.
