should be taken at the same time each morning. Since any activity may tend to raise your
temperature, do not get out of bed until you have taken your basal temperature. Postpone going
to the bathroom, eating, smoking or drinking until after taking your basal temperature. Hot drinks,
smoking and exercise cause higher readings. Using an electric blanket or heating pad can affect
your basal temperature. If you use one, it should be kept at the same setting each night
throughout the time you are taking your basal temperature.
The use of charting basal temperature will indicate the slight body changes taking place during the
menstrual cycle (the interval between the beginning of one period and the onset of the next
period). A pattern of temperature fluctuation in the monthly cycle will develop and be noticed. The
slight increase in basal temperature indicates ovulation or fertility by which a pattern of activity to
achieve conception.
Although, the generally accepted “normal” temperature of a healthy person is 98.6°F (37.0°C), the
basal body temperature in the first part of a cycle is usually in a range between 96.5°F (35.8°C)
and 98.0°F (36.7°C). In approximately the last two weeks of the cycle, the basal temperature is
typically 0.5°F (0.3°C) higher.
Note: The shift from the lower to the higher temperature occurs at around the time of ovu-
lation. Since ovulation (the release of an egg (ovum) from the ovary) ordinarily happens only
once during each menstrual cycle, charting basal temperature can be helpful in determining if
and when ovulation occurs. If intercourse takes place at or near this time, during the interval
of the transition between low and high temperature level, conception can take place.
Manual Calibration
The Tyto Basal Thermometer also measures the room temperature to accurately measure your
basal body temperature. The Tyto Basal Thermometer features a self-calibration mechanism,
activated automatically when turned on. Sometimes the device may require a manual calibration,
to verify the room’s ambient temperature to achieve the highest accuracy. In such cases, you’ll be
prompted by the Tyto device to run a short one-step calibration process.
When prompted, you’ll need to aim the
thermometer towards the plastic tray or
towards an inner wall, with some distance,
and then press Start to start the calibration
process, and measure the room
temperature.
