People with asthma have very sensitive airways that are constantly on the verge of over-reacting to asthma triggers. It doesn't take much for the airways to become inflamed, constricted, and filled with fluid. The constriction (think of wring a rag dry) is the narrowing of the bronchial tubes that leads to the bronchial tree. Making breathing very difficult.
What else can I help you with?
What makes the movement of air?
Differing air temperature causing cold air to sink, and warm air to rise is the main cause of air movement.
Would a cold can outside on a warm sunny day cause evaporation or condensation?

What causes a cars heater to blow cold air?

Are anticholinergics parasympathomimetics?
Parasympathomimetics are cholinergics. They effect the muscarinic receptors sites and cause bronchoconstriction or cause the closing of airways. Parasympatholytics are anticholinergics. They block the muscarinic receptor sites and prevent bronchoconstriction or prevent closing of airways. Source: I'm a 3.8 gpa Respiratory Therapy student.
Is bronchoconstriction sympathetic or parasympathetic?
Bronchoconstriction is due to an activation of parasympathetic nervous system.
What is the cause of thunderstorms?
the cause is when warm wet air and dry cold collide
What the cause of thunderstorms?
the cause is when warm wet air and dry cold collide
Pressure differences between warm and cold air masses cause what?
Pressure differences between warm and cold air masses cause fronts or high/low pressure systems. A warm front is when a warm, moist air mass slides up and over a cold air mass, and a cold front is the opposite.
What does air mass cause?
There are two types of air masses: COLD AIR AND WARM AIR.Cold Air Masses-Cold air masses can cause thunderstorms and even tornadoes.Warm Air Masses-Warm air masses can bring many hours of steady rain and snow.

Can a cP air mass break a cold spell?
No. cP means continental polar. Such an air mass can cause a cold spell.
What atmospheric conditions cause cold fronts?

Can a thermostat cause heater in house to blow cold air?
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
