Anxiety is an emotion characterized by feelings of worry, dread, and uneasiness. While it is a normal human response to stressful situations, it becomes a problem when it is excessive, persistent, and interferes with daily life. Anxiety is different from fear, which is a response to an immediate, present threat. Instead, anxiety is the anticipation of a future threat.
What happens in the body
When you feel anxious, your body’s “fight-or-flight” response is triggered. This is a natural reaction to perceived danger that floods your body with hormones like cortisol and adrenaline, preparing you to either confront or flee a threat.
Physically, this can result in:
- A rapid heart rate or palpitations
- Headaches, backaches, or other aches and pains
- Dizziness or lightheadedness
- Feeling restless or on edge
- Sweating
- Stomach problems, such as nausea or indigestion
- Shortness of breath
- Trembling or shaking
- Sleep disturbances
- Mentally and emotionally, anxiety can manifest as:
- Intense worry, dread, or a sense of impending doom
- Difficulty concentrating
- Irritability
- Feeling disconnected from your body or the world around you
- The urge to avoid things that trigger the anxiety.
When anxiety becomes a disorder
Anxiety is considered a mental health condition when the symptoms are very strong or last for a long time, are out of proportion to the actual situation, and make it difficult to function in everyday life. There are several types of anxiety disorders, including:
Generalized Anxiety Disorder (GAD): Persistent and excessive worry about routine events or activities.
Panic Disorder: Repeated episodes of sudden, intense fear that peak within minutes.
Social Anxiety Disorder: High levels of anxiety and avoidance of social situations due to fear of being judged negatively.
Specific Phobias: Intense, irrational fears of specific objects or situations.
Separation Anxiety Disorder: Excessive fear or worry about being separated from loved ones.
What causes anxiety?
The exact cause of anxiety is not known, but it is believed to be a complex mix of several factors:
Genetics: A family history of anxiety or other mental health disorders can increase your risk.
Environmental factors: Stressful or traumatic life events, both in childhood and adulthood, can contribute to anxiety.
Brain chemistry: Imbalances in certain neurotransmitters in the brain, such as serotonin and dopamine, are thought to play a role.
Underlying medical conditions: Symptoms of anxiety can sometimes be caused by a physical health problem, like a thyroid issue or heart disease.
How to manage anxiety
For many people, anxiety is a manageable condition. Self-care strategies and professional treatment can help.
Lifestyle changes: Regular exercise, a balanced diet, and avoiding or limiting alcohol and caffeine can all help.
Mindfulness and relaxation: Practicing deep breathing, yoga, and meditation can help calm your mind and body.
Talking to someone: Speaking with friends, family, or a therapist about how you feel can provide support and perspective.
Professional treatment: For anxiety disorders, a doctor or mental health professional may recommend psychotherapy (such as Cognitive Behavioral Therapy) or medication.
