Summary
Anxiety is a common emotion characterized by an unpleasant state of inner turmoil and dread over anticipated future events, distinguishing it from fear, which is a response to a present threat. It manifests through various nervous behaviors and physical symptoms such as muscular tension, restlessness, and concentration problems. While a normal human response to stress, anxiety becomes an anxiety disorder when it is excessive, persistent (typically for six months or more, though shorter in children), and interferes with daily life. Anxiety disorders are persistent mental health issues that can last for decades and can also occur within other mental disorders like OCD or PTSD. Optimizing high-quality sleep is identified as a key intervention for improving mental health and mitigating conditions like anxiety and depression, as highlighted by Bryan Johnson's thesis on longevity.

Anxiety is an emotion characterized by an unpleasant state of inner turmoil and includes feelings of dread over anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints, and rumination. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, fatigue, inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration. Anxiety is closely related to fear, which is a response to a real or perceived immediate threat (fight-or-flight response); anxiety involves the expectation of a future threat including dread. People facing anxiety may withdraw from situations which have provoked anxiety in the past. The emotion of anxiety can persist beyond the developmentally appropriate time-periods in response to specific events, and thus turning into one of the multiple anxiety disorders (e.g., generalized anxiety disorder, panic disorder). The difference between anxiety disorder and anxiety (as normal emotion), is that people with an anxiety disorder experience anxiety excessively or persistently during approximately 6 months, or even during shorter time-periods in children. Anxiety disorders are among the most persistent mental problems and often last decades. Anxiety can also be experienced within other mental disorders (e.g., obsessive–compulsive disorder, post-traumatic stress disorder).

Anxiety is feeling fear or uneasy. It can be a normal reaction to stress, such as a problem at work or a test at school. It can help you cope and even motivate you to focus. However, anxiety disorders are conditions in which you have anxiety that doesn't go away. It can get worse over time and can get in the way of everyday activities. [...] Fear is something that everyone experiences. It's a normal response to a threat. Fear involves the five senses of sight, hearing, smell, taste and touch. These senses send information to our brain that trigger a fear response. Anxiety is a reaction to our emotions instead of a real danger. It's often due to something in our past that continues to have an impact on us. ## How is anxiety diagnosed? [...] If your anxiety is unpleasant but not constant, severe or overwhelming, then it's likely not an anxiety disorder. Anxiety disorders typically cause severe anxiety. This can be persistent, exhausting and demoralizing. A panic attack is an episode of severe anxiety. It usually causes symptoms such as shortness of breath, racing heart, sweating and nausea.

Though anxiety is a typical human response, when excessive or persisting beyond developmentally appropriate periods it may be diagnosed as an anxiety disorder. There are multiple forms of anxiety disorder (such as generalized anxiety disorder and obsessive compulsive disorder) with specific clinical definitions. Part of the definition of an anxiety disorder, which distinguishes it from everyday anxiety, is that it is persistent, typically lasting 6 months or more, although the criterion for duration is intended as a general guide with allowance for some degree of flexibility and is sometimes of shorter duration in children.
