Answer:
It can improve concentration and performance.
Step-by-step explanation:
Stress is a form of reaction of the human body to troublesome situations. There are different levels of stress, so the higher the stress, the worse the health consequences. A very stressed person may have emotional and heart system problems, in which case you need to reduce stress with professional help. However, low and moderate stress levels do not always have only negative effects. Stress can serve as an inducer for a better focus on a pressure scenario, such as a test. It is common for people who are relatively stressed about an exam to perform better than those who are not so concerned about the exam.
