Answer:
Cortisol
Step-by-step explanation:
The hormone cortisol is essential for the proper functioning of the immune system. The substance is also known as the stress hormone. This is because when we get stressed, we usually release an excess amount into our body, resulting in a number of unintended consequences.
A discussion is a very stressful time, so we can say that when Bethany gets involved in a discussion, she gets stressed and that stress increases cortisol production in her body.
Stress is one of the main factors for increasing cortisol. It is therefore important to work on emotional intelligence and try to avoid situations where you know you will be stressed as much as possible.
