🏥 Health & Wellness Air Quality Safety measures Chronic Conditions
  1. Increased wildfire activity due to climate change is causing a rise in toxic particulate pollution in the air, impacting everyone's health but particularly risky for those with chronic conditions.
  2. Wildfire smoke contains harmful PM2.5 particles that can lead to respiratory issues, trigger asthma flares, and increase the risk of viral infections.
  3. To protect yourself from wildfire smoke, monitor air quality, keep windows closed when AQI is high, use air purifiers with HEPA filters, avoid outdoor exercise in hazy air, and consider wearing a KN95 or N95 mask if at high risk.

Improving Indoor Air Quality

Metabolic Repair • 19 implied HN points • 09 Aug 24
🏥 Health & Wellness Air Quality Pollution Health Effects
  1. Indoor air pollution can harm your health and comes from sources like cars and chemicals. To improve air quality, think about using air filters designed for particle and chemical removal.
  2. It's important to monitor the levels of CO2 and humidity in your home. Too much CO2 can make you feel tired and less focused, while high humidity can lead to mold growth.
  3. Homeowners can use Energy Recovery Ventilators (ERVs) to exchange indoor and outdoor air while controlling humidity and temperature, but renters can also improve air quality by using air filters and keeping windows open when outdoor conditions are good.

How does the Air Quality Index work anyways?

Counting Stuff • 43 implied HN points • 13 Jun 23
🔬 Science Environmental Science Data science Air Quality
  1. The Air Quality Index is a single score that combines 6 pollutants into a usable number for people to understand.
  2. Time frames are important in the AQI, as it is based on daily air quality summaries and forecasts are encouraged for planning purposes.
  3. The AQI simplifies complex air quality data by using a linear scaling system, with the max value among pollutants determining the overall index.
