Anxiety is a feeling of worry, nervousness, or fear about an event or situation. It is a normal reaction to stress. It helps you stay alert for a challenging situation at work, study harder for an exam, or remain focused on an important speech.
Difference Between Stress and Anxiety. Although the terms âstressâ and âanxietyâ are typically used interchangeably in everyday conversation, there is a difference. Stress, unlike anxiety, is a response to daily pressures. These pressures, in turn, cause adrenaline to be released, which then can lead to depression, raised blood pressure and other negative health side-effects.
