Common signs and symptoms of stress include:

The signs and symptoms of stress are often characterized by physical and emotional responses to challenging situations. When individuals experience stress, they might exhibit tension in their muscles, leading to feelings of irritability as the body remains in a heightened state of alertness. Dry mouth can occur due to the body's flight-or-fight response, which can cause a decrease in saliva production. These physiological changes reflect the body's preparation to deal with perceived threats and are well-documented indicators of stress.

In contrast, other options suggest positive emotional and physical states, such as increased energy, relaxation, and clarity of mind, which are not generally associated with stress. Instead, those feelings might be seen in states of well-being or accomplishment, not stress.
