Causes of Anxiety

Simple Causes: The anxiety doesnít necessarily indicate any major psychological disorder. There are various simple causes:

  • Normal anxiety. If the anxiety is occurring in relation to a real, rational concern, such as a problem, risk, or threat, some level of anxiety is normal.
  • Excitement, anticipation. Feeling anxious about something that is about to happen, or is as yet undecided, can be quite rational.
  • Physical illness. There is a tendency for extra anxiety in response to an illness, such as a viral infection.
  • Poor diet. Having an inadequate diet can exacerbate anxiety, although itís not really a cause of anxiety by itself.
  • Sleep deprivation. Not having enough sleep tends to make people more likely to be anxious.
  • Changes to Routine. Some people, especially elderly people, become more anxious when their normal routine is changed or interrupted.
  • Hyperventilation. When a person hyperventilated (perhaps due to anxiety), this causes difficulty breathing, which exacerbates anxiety, and a vicious cycle can occur.
  • Nightmares and night terrors. A common cause of anxiety in children.
