What Is Anxiety? Understanding the Basics

Anxiety is something most people experience from time to time. Whether it’s pre-exam nerves, worry before a big presentation, or concern about a loved one, these feelings are a normal part of life. But when does typical worry cross the line into something more serious? Understanding anxiety—how it feels, why it happens, and when it becomes a concern—can help you take charge of your mental health and know when to seek support.



What Does Anxiety Feel Like?

Anxiety often shows up as a sense of unease, dread, or fear. It can be physical, too: a racing heart, sweaty palms, tense muscles, or even feeling dizzy. These are natural responses triggered by the body’s “fight or flight” mechanism—a survival system that kicks in when we sense danger. For most, these feelings pass once the stressful event is over.

But for some, anxiety lingers or appears without a clear cause. It might show up as persistent worry, difficulty concentrating, irritability, or trouble sleeping. Sometimes, anxiety becomes so overwhelming that it interferes with everyday life. If you recognize these symptoms in yourself or someone you care about, it’s important to know you’re not alone—and that help is available.

The Difference Between Everyday Anxiety and Anxiety Disorders

Everyone feels anxious sometimes. However, anxiety disorders are different: they involve more intense, persistent, or uncontrollable anxiety that disrupts daily living. Nearly 1 in 3 adults in the United States will experience an anxiety disorder at some point in their lives.

So, what separates normal anxiety from a clinical disorder? It often comes down to severity, duration, and impact. Occasional stress about a work deadline is normal, but ongoing, excessive worry that affects your relationships, job, or health may point toward an anxiety disorder.

Types of Anxiety Disorders

Anxiety can take many forms. The most common types include:

Generalized Anxiety Disorder (GAD)

People with GAD experience chronic, excessive worry about a range of everyday things—finances, health, work—even when there’s little reason for concern. The anxiety feels hard to control and may last for months or even years.

Panic Disorder

Panic disorder involves sudden, intense episodes of fear known as panic attacks. These attacks can include symptoms such as chest pain, heart palpitations, shortness of breath, and a feeling of impending doom. Panic attacks can occur without warning and may cause individuals to avoid situations where attacks have happened before.

Social Anxiety Disorder

Social anxiety goes beyond shyness. It’s a persistent fear of social or performance situations, where you may worry about being judged, embarrassed, or rejected. This can make everyday activities—like going to work, school, or social gatherings—feel overwhelming.

Specific Phobias

Phobias are intense, irrational fears of specific objects or situations, such as heights, flying, or certain animals. These fears can trigger immediate anxiety and lead people to avoid the thing they fear, even if it poses little real danger.

Other Types

Other anxiety-related conditions include separation anxiety disorder (often seen in children but can affect adults), agoraphobia (fear of places where escape may be difficult), and health anxiety.

What Causes Anxiety?

Anxiety doesn’t have a single cause. Instead, it’s shaped by a blend of factors:

• Biology: Some people may be genetically predisposed to anxiety. If you have a family history of anxiety or other mental health conditions, your risk may be higher.
• Brain Chemistry: Imbalances in certain neurotransmitters (brain chemicals) can contribute to anxiety symptoms.
• Life Events: Stressful or traumatic experiences—such as the loss of a loved one, accidents, or major life changes—can trigger anxiety.
• Personality: People who are more sensitive or who tend to see situations as threatening may be more susceptible.
• Medical Conditions: Sometimes, anxiety is linked to underlying health problems, such as thyroid disorders or heart arrhythmias.

Common Triggers for Anxiety

Everyone’s experience with anxiety is unique, but some common triggers include:

• Major life changes (moving, starting a new job)
• Chronic stress at work or home
• Social situations or public speaking
• Financial concerns
• Health worries
• Certain medications or substances (like caffeine)

Identifying your own triggers can be a helpful step toward managing anxiety more effectively.

When Should You Seek Support?

Remember, anxiety disorders are highly treatable, and most people feel better with the right help. Treatment options may include therapy, medication, or lifestyle changes, and your mental health provider can help you find what works best for you.
