Weathering the weather is the latest environmental challenge we have to deal with these days. Wildfires. Saharan dust. Humidity. Drought. Soaring temperatures. If you live in the south or in any number of the western states, you are likely to be affected by wildfire smoke or Saharan dust this summer. It seems that each year, our lungs are being assaulted more and more with the prevalence of harsh, hot temperatures and dust that can seriously impede our breathing and our overall health.
