Last week we launched a report called "Does exercising in Jakarta's air pollution impact our health?" which includes a deep-dive into the air quality in Jabodetabek from 4-9AM when most people exercise.
Here's some of the things we found
Here's some of the things we found
Overall, The cost of air pollution in Jakarta is large, but what's more concerning is a general lack of data on health impact. The last available data was from 2010, nearly 10 years ago.
This posed a challenge for us - how do we correlate the air quality with health risk?

The University of Cambridge released a report in 2016 which concluded that long-term exposure to PM2.5 poses a health risk to people exposed to very high concentrations of air pollution.

The scale was simple:
PM2.5 > 100 ug/m3
After 90 minutes, health risks of air pollution outweigh benefits of exercise
PM2.5 > 165 ug/m3
After 30 minutes, health risks of air pollution outweigh benefits of exercise
What did that mean for 4-9AM in Jakarta?
Here's the data

PM2.5 > 165 ug/m3

What did that mean for 4-9AM in Jakarta?
Here's the data
In August 2020, between the hours of 4 and 9AM, the air quality on average frequently exceeded the 100 ug/m3 limit - meaning that the recommended time to exercise would be below 90 minutes.
Some places had averages above >165 ug/m3!!!
Some places had averages above >165 ug/m3!!!
There was significant variance across the month from city to city, and by time of the month.
Note - the data below shows the average PM2.5 level for the entire block of time between 4-9AM.
Maximum hourly readings are higher.
So when is air quality actually good?

We took a look at the average hourly readings from the entire month, and something surprising emerged (at least for us non-atmospheric scientists).
The best air quality is during the day - which is a bit shocking when you previously thought that day = cars = bad.

The report is filled with a lot more details including:
- Best day of the week
- Detailed air quality by kecamatan (district) in each of the cities
- Risk index created based on occurrence of air pollution that is above PM2.5 100 ug/m3

So if you love exercising in Jabodetabek in the morning, or just want to see more of the data, here are the links to the reports - dual-language for easy understanding!

There are a few safe steps you can take to exercise outdoors when air quality is bad.
It starts with checking your air quality.
@nafasjkt has over 50 sensors in Jabodetabek to tell you the current air quality.

The most recent release of the app includes features made for people who like to exercise, but that's for another thread :)
