Frankly, this! You can read from the other comments that it is not common knowledge yet what stress actually does to you. Stress as a facility is useful for humans and other animals. It helps the body to focus on the threat and increase the chance to escape and survive. Stress makes a tiny damage to the health but once you survive, the body returns to health. However, there are cases where you have long-term continuous stress, without any release. It is common with social animals like humans, and an example is the burn-out. The tiny damage becomes major damage and can be irreversible.
