Question

Kerrie plays tennis and is entered in this weekend’s big tournament. She has allergies, but knows she has to avoid taking antihistamines because they make her drowsy. After the first match she still finds herself very tired. This season’s allergies are causing a lot of mucus production and coughing, and she says her chest feels congested and constricted. You tell her this is the cause of her tiring easily. Why?

Answer 1

Answer:

She tires easily due to the lacking oxygen.

Explanation:

Kerrie's mucus and coughing is a reaction from her body trying to fight something that her body recognizes as a treat for her immune system. As she is producing a lot of mucus and coughing while practicing a sport, she is not inhaling the necessary oxygen that her muscles need to perform this activity well, as a result, she gets tired.
