What is Anxiety?

Can anxiety cause fever? As per the American Psychological Association, you have anxiety when you have emotional stress, tension, worrying thoughts, and physical causes like increased blood pressure. Anxiety is normal in human beings, but when they become pronounced in the form of sweating, increased heartbeat, or increased sensitivity to the surroundings, it is better to seek medical help.
