Anxiety is your body’s built-in alarm system. It’s meant to keep you safe — sharpening your focus before an exam or making you jump back from a curb. Problems start when the alarm goes off too often, too loudly, or when there’s no real danger. Here’s a clear, plain-language guide to what anxiety is, what causes it, and what helps.

Normal anxiety vs. an anxiety disorder
Everyone feels anxious sometimes. According to NIMH, an anxiety disorder is different: the anxiety doesn’t go away, can get worse over time, and interferes with daily activities like work, school, and relationships. NIMH estimates that 31.1% of US adults experience an anxiety disorder at some point in their lives.
Common types of anxiety disorders
- Generalized anxiety disorder (GAD): persistent, hard-to-control worry about everyday things
- Panic disorder: repeated, unexpected panic attacks — see what to do during a panic attack
- Social anxiety disorder: intense fear of being judged — see social anxiety
- Phobias: intense fear of specific objects or situations

| In the mind | In the body |

What causes anxiety?
NIMH notes that both genetic and environmental factors play a role. Stressful or traumatic life events, certain personality traits, other health conditions, and substances like caffeine can all contribute. Often there isn’t a single cause — see why do I feel anxious for no reason?
