-Or maybe it’s just that, at temps above 85degF or so, there’s (a) just not as much O2 in a gulp of air as in cooler air. If you’re old enough to remember carburated cars, it always wanted to die out as you came to a stop becasue the air/fuel mix needed to be 14.5:1 and was set at cooler temps with more )2 per cc. If you’ve got COPD and have borderliine O2sat, that little bit makes a big difference in your blood oxygenation.
-And (b) thermal inversion keeps the road dirt down near the road cuz the warmer, lighter air is held down more by the cooler upper air. Asthma is a disease of excessive airway sensitivity to airborn dust.
-It’s not “the chemicals” in the air. It’s just its physical properties.
Make sure your tires are inflated to the correct tire pressure. Over or under inflation can affect you fuel economy. Purchase a tire pressure gauge and use it at every fill up.
