How do your peak flow values at sea compare to your values at home? I’m thinking the fresh clean air of the ocean might be a blessing but what about the temperature and humidity swings?

Dear John: My asthma is well controlled, and so the peak flows are about the same at sea and on land. Where there may be a benefit from the clean ocean air, perhaps that is offset by the constant stress which is also a trigger for my asthma. Temperature and humidity swings have never seemed to be a problem for my asthma.
