What Is Anxiety?
Anxiety is a natural response to pressure or perceived threat. It shows up in how we feel physically, mentally, and in how we behave. Occasional anxiety is a normal human experience — feeling nervous before a job interview or worried about a loved one is completely natural.
However, for people with anxiety disorders, anxiety goes beyond occasional worry. The key distinction is that anxiety does not go away, is felt across many situations, and can get worse over time. About a third of U.S. adolescents and adults experience an anxiety disorder at some point in their lives.
Types of Anxiety Disorders
Anxiety disorders take several forms, each with distinct characteristics:
- Generalized Anxiety Disorder (GAD) — persistent, excessive worry about various aspects of daily life such as health, work, finances, or relationships
- Panic Disorder — recurring, unexpected panic attacks with intense physical symptoms like rapid heartbeat, sweating, and shortness of breath
- Social Anxiety Disorder — intense fear or anxiety in social situations, particularly around being judged or embarrassed
- Phobia-related Disorders — extreme, disproportionate fear of specific situations or objects (e.g., agoraphobia, claustrophobia, specific phobias)
- PTSD — anxiety linked to traumatic past experiences
A fear becomes a phobia when it is out of proportion to the danger, lasts for more than six months, and significantly impacts your day-to-day life.

What Causes Anxiety?
Anxiety disorders develop from a combination of factors, and sometimes there is no obvious single cause. Common contributing factors include:
- Life experiences — stressful or traumatic events, major life changes
- Genetics — family history of anxiety or other mental health conditions
- Personality — some people are naturally more prone to anxiety
- Upbringing — childhood experiences and learned responses to stress
- Health conditions — physical illness or chronic pain
- Lifestyle factors — excessive caffeine, alcohol, or substance use; poor sleep; lack of exercise
Common triggers include work pressure, financial worries, relationship difficulties, health concerns, housing or job insecurity, and bereavement.
Self-Help Strategies
These evidence-based strategies may help manage anxiety symptoms:
Shift your focus
Practice mindfulness and breathing exercises to bring your attention to the present moment rather than future worries. Even a few minutes of focused breathing can help calm the nervous system.
Understand your anxiety
Keep an activity and emotion diary to track patterns. Understanding what triggers your anxiety and how it manifests helps you prepare and respond more effectively.
Make time for worries
Designate a specific daily "worry period" — perhaps 15 minutes at the same time each day. When worries arise outside this time, write them down and save them for your worry period. Many worries feel less urgent by the time you revisit them.
Face fears gradually
Avoiding things that make you anxious can reinforce the anxiety over time. Instead, try gradual exposure — start small and slowly work your way toward situations that feel challenging. This process, sometimes called systematic desensitization, can reduce anxiety over time.
Challenge your thinking
Ask yourself: Is there evidence for this worry? Is there another way to look at this situation? Cognitive behavioral approaches help you recognize and reshape unhelpful thought patterns.
Take care of your body
- Get regular physical activity — even 30 minutes of walking can improve mood
- Maintain consistent sleep schedules
- Reduce alcohol and caffeine
- Eat balanced, regular meals
- Spend time outdoors
Connect with others
Talking to someone you trust about how you feel can help. Social connection reduces isolation and provides practical and emotional support. If talking feels difficult, try writing down your feelings first.
Treatment Options
If self-help strategies are not enough, several effective professional treatments are available:
- Cognitive Behavioral Therapy (CBT) — helps you identify and change unhelpful thinking and behavior patterns. CBT is considered the gold-standard treatment for anxiety disorders.
- Applied relaxation — teaches you to relax your muscles in situations that normally cause anxiety
- Medication — SSRIs (such as sertraline) or other antidepressants may be prescribed for persistent or severe anxiety
- Talking therapies — various forms of counseling and psychotherapy
- Exposure therapy — particularly effective for phobias and specific anxiety disorders
Treatment often combines approaches. Research continues to investigate which treatments work best for specific individuals.
When to Seek Professional Help
Consider reaching out for professional support if:
- Anxiety symptoms persist for several weeks
- Anxiety interferes with daily activities, work, or relationships
- You are avoiding situations or places because of anxiety
- Physical symptoms (chest pain, dizziness) are concerning
- You feel unable to manage anxiety on your own
- You are using alcohol or other substances to cope
You do not need a referral to access many mental health services. In many cases, you can self-refer for talking therapies.
