  1. Rest: Lie down with feet elevated for 10 to 20 minutes. (Reason: simple fainting is due to temporarily decreased blood flow to the brain.)
  2. Sugar: Drink some fruit juice, especially if you have missed a meal or have not eaten in more than 6 hours.
  3. Fluids: In hot weather, drink several glasses of cold water and apply a cold wet washcloth to the forehead.
  4. Prevention: For fainting associated with prolonged standing, eat more salty foods and drink more fluids every day.
  5. Pregnancy Test When In Doubt:
  6. Call Your Doctor If:
    • You pass out again on the same day
    • You are pregnant
    • You become worse
