What is an anxiety disorder?

We speak of an anxiety disorder when anxiety frequently arises in non-dangerous or non-threatening situations and it interferes with your daily life.

Anxiety is an emotion you experience and is a human and healthy reaction to a dangerous or threatening situation. Thus, feeling fear is functional. For example, fear causes you to run away in a dangerous situation. The function of fear becomes less functional and even disturbing when fear arises outside of typical, functional cases.

Symptoms

An anxiety disorder can show up in different ways. Some people mainly experience intense emotions, while others notice physical symptoms first. Often, it’s a combination of both. You may experience one or more of the following symptoms, even though there is no real danger:

Emotional and psychological symptoms

  • Recurrent, intense anxiety, or a mild but constant sense of fear
  • Feeling restless, stressed, worrying a lot, or constantly nervous
  • Feeling like you always have to be on guard, “always on”
  • Avoiding certain situations, places, or people

Physical symptoms

  • Cold hands, shortness of breath, sweating, or trembling arms and legs
  • Increased heart rate, even when resting
  • Nausea, a “knot” in your stomach, diarrhea, or vomiting
  • Difficulty relaxing, concentration problems, increased irritability

How does an anxiety disorder develop?

An anxiety disorder usually does not have one single cause. It often develops through a combination of vulnerability and life circumstances.

  • Genetics and vulnerability. Anxiety disorders can partly run in families. This does not mean you will automatically develop one, but you may be more sensitive to anxiety.
  • Upbringing and protection. A safe and caring bond with parents is important. At the same time, children need chances to face challenges. When children are constantly protected or reassured, they may miss opportunities to learn that they can handle difficult situations themselves. This can increase anxiety later in life.
  • Cognitive processing. Sometimes anxiety develops because everyday sensations or situations are interpreted as dangerous. People may overestimate danger and underestimate their ability to cope.
  • Stressful or traumatic events. An intense or traumatic experience can increase sensitivity to anxiety. After a very frightening situation, the brain may label similar situations as dangerous, even when they are safe.

Normal anxiety can turn into an anxiety disorder when it lasts a long time and becomes stronger. This is often explained by the vulnerability–stress model: someone has a sensitivity to anxiety, and stressful circumstances trigger the disorder. Avoidance also plays a key role. By avoiding situations, the brain never learns they are safe, and anxiety becomes a fixed pattern.

Not everyone exposed to these factors develops an anxiety disorder. Protective factors such as social support, resilience, and helpful coping skills make a big difference.

Types of anxiety disorders

“Anxiety disorder” is an umbrella term. Common types include:

Self care

If you experience anxiety symptoms, there are things you can do to reduce these symptoms. 

  1. Physical activity improves mood, sleep, and energy. Being outdoors helps shift focus away from anxious thoughts.
  2. Talk about it. Sharing your worries with friends, family, or your partner can make anxiety more manageable.
  3. Take care of your body. Eat well and giver yourbody time to rest. Limit your alcohol, cigarettes or drugs.
  4. Practice relaxation. Mindfulness can help you calm your mind, improve sleep, and cope better with anxiety.

If symptoms persist, talking to a psychologist is a wise step. A psychologist can help you learn how to manage anxiety more effectively.

Treatment

Treatment for an anxiety disorder focuses on reducing symptoms and restoring daily functioning. The goal is not only to reduce anxiety, but mainly to learn how to relate differently to anxious thoughts, feelings, and physical sensations. In treatment, you learn to:

  • Understand how your anxiety works
  • Recognize triggers such as situations, thoughts, or bodily signals
  • See how avoidance keeps anxiety going
  • Gradually face feared situations again
  • Build confidence in your ability to cope with stress

Treatment also focuses on strengthening resilience and developing helpful coping strategies. The goal is not always to eliminate anxiety completely—anxiety is a normal emotion—but to ensure it no longer controls or limits your life.

Anxiety disorders are commonly treated with Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT).

FAQ

Anxiety is a normal emotion. In an anxiety disorder, anxiety is out of proportion or occurs without a clear reason and strongly affects daily life.

Fear of fear is very common. Therapy helps you understand this cycle and become less affected by it.

Can I manage my anxiety on my own?

You can start with self-help tips. If that’s not enough, a psychologist can teach you new ways to handle anxious thoughts and feelings.

How do I explain my anxiety disorder to others?

Anxiety disorders are often invisible. We help you find words to explain it to your partner, employer, or friends in a way that feels right for you.
