Q. Why do some people gain weight when they feel stressed?
A. People who eat in response to stress are likely to find themselves packing on pounds for the same reason other people gain weight – because they are eating more calories than they are burning. However research also suggests that chronic stress raises the level of chemicals that increase appetite, especially for food rich in carbohydrates.
Q. Are you more likely to get sick when you are stressed?

Q. How does stress affect my heart?

Q. Is stress always bad?

That's why it's important to learn how to manage stress. You may not be able to avoid stressful situations, but you can learn how to change how you respond to them.
