What is Anxiety? Symptoms, Causes & Treatment
Introduction
Anxiety is a natural response to stress or danger. Everyone experiences anxiety occasionally before an exam, interview, public speaking event, or important life decision. However, when anxiety becomes excessive, persistent, and starts affecting daily life, it may develop into an anxiety disorder.
In today’s fast-paced world, work pressure, financial stress, unhealthy lifestyles, excessive screen time, lack of sleep, and social expectations have made anxiety one of the most common mental health concerns worldwide.
This guide explains what anxiety is, its symptoms, causes, treatment options, and ways to manage it effectively.
