The following is provided by an eminent southern Asthma and allergy physician . .  . who has hiked Half Dome.

    If you have asthma and want to go hiking, there are things you need to consider. But before we go into that, let’s go over some asthma basics. Asthma is reversible obstructive airways disease. The obstruction is caused by two things, airway muscle constriction and inflammation in the airways. Things that trigger this obstruction may vary from individual to individual. Allergies, respiratory tract infections, sinus disease, stomach reflux, irritants (smoke, air pollution, strong odors, etc.), exercise and even food allergies can trigger symptoms.

Asthmatics usually know the things that are likely to set them off. Exercise causes the rapid movement of air up and down the airways which may cause wheezing. This tends to be worse with cold dry air. Running causes more rapid air movement than bicycling. That is why cross country runners have more difficulty than cyclists or swimmers. They also tend to be worse in winter environments. Before you hike, make sure your asthma is stable. If your asthma has been acting up, wait until it is stable before you hike. Stay on all of your maintenance medications and make sure you have been taking them weeks before your hike. Make sure you take your “rescue” inhaler, and it doesn’t hurt to have a spare. If you always wheeze when you hike, you might want to consider Warm up periods before exercise can be a big help. Start off slowly and take your time.
    Hiking is not a race. If you begin to have problems, slow your pace. Take frequent rest stops.
If the air is cold, try to breathe thru your nose or wear a scarf over your face so you are re-
breathing some of the warm, humid air you are exhaling. Cold air exercise masks are useful.  Make sure you drink lots of water. Failing to do this is the biggest mistake hikers make, and it is double trouble for asthmatics. If you don’t have to urinate periodically, you aren’t drinking Finally, if you begin to have problems, STOP. Use your medications and take a long rest until things are well under control. Don’t force it. Let your friends about your problem. If you don’t feel right, don’t do it. Slowly go back down. There will always be another day.
   

    Editor comment: Speaking of noses…did you know that of all animals, bears have the strongest sense of smell. A dog’s sense of smell is 100 times stronger than a human, while a bear’s sense of smell is 7 times stronger than a bloodhound or 2,100 times stronger than that of a human. Don’ think they can’t find your hidden candy bar.
Unrelated thought worth quoting: “There is not a fragment in all nature, for every relative fragment of one thing is a full harmonious unit in itself.” – John Muir, 1867
