(HealthDay News) -- Dealing with a disaster can be emotionally overwhelming, and everyone responds somewhat differently.

The American Psychological Association says possible responses to disaster include:

  • Emotional reactions, including moodiness, irritability and unpredictable behavior.
  • Physical changes, including disturbed sleeping and eating patterns.
  • Acute sensitivity to environmental factors, such as a siren or the smell of something burning.
  • Strained personal relationships.
  • Physical symptoms of stress, such as chest pain, headache or nausea.
