Anxiety is an emotion that occurs in response to thoughts about possible threats; a tool of the self-preservation instinct.
Anxious thoughts originate in the amygdala, two small parts of the brain located in the temporal lobes, one each on the right and left.
Anxiety refers to worry, worry about events that have not yet occurred, and fear is an emotional reaction to current events.
Along with mental changes, these feelings also provoke physical symptoms - sweating, increased heart rate, breathing, and a feeling of lightheadedness.
The heart rate may also increase, it may be difficult for a person to sit in one place, people feel pain and tightness in the chest, sweating increases, and nausea and diarrhea occur.
Some people feel numbness and tingling in their extremities, weakness, muscle tension, fever and dizziness.
Anxiety is a personality trait that manifests itself in a feeling of excitement, anxiety, or concern that arises for minor reasons.
It can simply be an individual feature, a variant of the norm, or a sign of an organic or functional disorder in the body.
A test that detects signs of anxiety in the blood could be a game-changer for mental health care, a new study suggests.
We've previously talked about mixed signals in relationships.
