  • Take a clinical thermometer and hold it horizontally with reading scale towards your eye.
  • Do not hold the thermometer from the bulb.
  • Rotate the thermometer slightly clockwise and anticlockwise. By doing this you will see a shiny thin silvery thread.
  • The end of the silvery thread shows the reading of temperature. If mercury lining ends at 37, the reading is 37°C.
  • Wash the bulb end of thermometer with an antiseptic solution.
  • Give two or three jerks slightly. By doing this the mercury level would fall. When it falls to 35°C or below, put it below the tongue and wait for one minute.
  • Take out the thermometer and read the temperature. Temperature would be near 37°C.
  • The normal body temperature is 37°C. This can differ from person to person.
