What should I avoid doing while I measure my BBT?Updated a month ago

BBT is sensitive and can be disrupted by several things. While taking your BBT, please note that the following may give you an artificially high or low temperature:

• Eating, drinking, or doing any activity before taking your temperature
• Illness, especially fever
• Alcohol use the day before (going to bed drunk or tipsy)
• Electric blankets or heating pads
• Sleeping in a room that’s unusually hot or cold
• Travel, especially across time zones
• Day Light Savings
• Poor sleep
• Going to bed later than usual or waking up earlier than usual
• Taking your temperature at a later or earlier time than usual (over an hour)
• Certain medications

We also recommend keeping your mouth closed for at least two minutes before taking your temperature.

The most important piece of taking your BBT is consistency!
