I have mild asthma. I needed an inhaler when I was less aware of how to manage my asthma.
The following things work for me:
- Use "natural" cleaners 99% of the time: soaps, shampoo, household cleaners, laundry detergents.*
- Make sure clothing and living spaces are fairly clear of allergens : try to avoid spaces with mold inside the walls or large amounts of dust. Wash clothes and sheet more often if allergies are a problem.
- Avoid excessive stress and enjoy life.
- Do not use scented deodorant/antiperspirant.
- When possible, stay away from people who wear perfume/cologne.
- Don't do sprinting or similar cardiovascular exercise without doing gradual, long term training for it. DO exercise often.
*I avoid mineral oil. Oil is in soaps/detergents, and mineral oil is the norm because it's cheap. Mineral oil is also used in antacid tablets and gummy candies. It's made from petroleum.
