What happens if you are exposed to an allergen or asthma trigger?

ANSWER

If you are exposed to an allergen or asthma trigger, it’s very likely that it’ll quickly set off an allergic asthma or other reactions. The asthma attack will end within a hour. About half of the time, you may get another episode 3 to 8 hours later. This is called the late phase response. That second phase is more likely to happen and be more severe if you’re exposed to allergens in the evening instead of in the morning.
