Temperature Disturbances

A rise in temperature is noted, is it a true thermal shift?

Not every rise in temperature indicates a thermal shift. A temperature disturbance is a false temperature rise due to causes other than ovulation. Factors that can disturb the temperature should always be noted in the chart and a disturbed temperature is marked with a circle and discounted when interpreting the temperature chart.

Causes of a disturbance of the Temperature (Basal Body Temperature, BBT):

• Taking the temperature at a different time that usual.
• Taking the temperature in a different orifice that usual.
• Using a different thermometer.
• Alcohol intake the night before.
• A Disturbed night.
• Sleeplessness
• Fever due to illness.
• Travel/ Holidays
• Stress
• Emotional upsets
• Medication
• Heavy meal before sleeping
