what are some of the physical signs of stress?

Brief Explanations:

Stress can manifest physically. Common signs include increased heart rate, which is the body's response to stress hormones like adrenaline. Muscle tension, especially in the neck, shoulders, and back, occurs as the body prepares for a "fight - or - flight" response. Headaches may result from the constriction and dilation of blood vessels in the head due to stress. Digestive issues such as an upset stomach or changes in bowel habits can happen because stress affects the digestive system's functioning. Fatigue is also a sign, as the body expends a lot of energy dealing with stress.

Answer:

Increased heart rate, muscle tension (e.g., in neck/shoulders/back), headaches, digestive issues (e.g., upset stomach, changes in bowel habits), fatigue.
