Explain what would happen if your epiglottis stopped working properly.

The epiglottis is a flap that prevents air from going down the esophagus and stops food from going down the trachea.
If this stopped working, you wouldn't be able to swallow your food, or breathe properly, and you'd probably choke and eventually die from it.

The answer to your question is  it relieves stress and boredom.  the rest of the answer choices would be long term. 

You should only go in for less than 10 minutes at a time, or avoid them altogether, especially in the early weeks. studies have shown an increased risk for birth defects in babies of women who had an elevated temperature before 7 weeks of  pregnancy.
