A Mercury-Free Glass Basal Thermometer As an alternative to mercury thermometers, the Fairhaven Health Glass Basal Thermometer is highly accurate and family-friendly. Containing an environmentally-safe liquid alloy, the Fairhaven Health thermometer is completely non-toxic; in the event it breaks, it can simply be cleaned up with warm, soapy water. Better yet, the non-mercury glass basal thermometer is ultra-accurate, exceeding standards for accuracy. Using non-toxic alloy instead of mercury, the no-mercury glass basal thermometer is capable of measuring the slightest temperature increases. The Fairhaven Health basal thermometer exceeds ASTM standards with an accuracy of +/- 0.1 F. |
What's a basal thermometer?
A basal thermometer is a highly sensitive thermometer that tracks
your body’s resting (or basal) temperature and measures precise
changes of 1/10th of a degree in temperature. By charting your basal
temperature daily, you'll know when you ovulate during your cycle
and be able to predict when you are most fertile.
Ovulation - the most fertile time during your menstrual cycle - is the moment a mature egg is released from the ovary. Once released, the egg has a life span of about 24 hours. Conception is most likely to take place at this time - so precise ovulation prediction is key. "Peak fertility" is considered to be the day before and the day of ovulation. As the egg can survive about 24 hours, conception must take place within this window. Your “fertile period” begins about 4 to 5 days preceding ovulation due to the fact that sperm can survive in your body for several days.
How
do I use the mercury-free glass basal to fertility chart?
The first day of your menstrual flow is DAY 1 on your fertility
chart. Begin keeping track of your temperature on the first day
of your menstrual period (first day you see red blood). Record your
basal temperature every morning throughout your cycle (as well as
other fertility signs listed on the chart). During the first two
weeks or so of a woman's cycle, her body temperature is lower. When
you ovulate, a noticeable rise in body temperature takes place.
A minimum temperature rise of 0.4 to 0.6 F can be measured - and
this change will typically last through the duration of the menstrual
cycle. If you know when this "thermal shift" is going
to happen in your cycle, you can predict ovulation and the best
time to time intercourse.
Disposing
of your old mercury basal thermometer:
Mercury
basal thermometers are no longer available in most states in the
US - or will be removed from shelves shortly. If you elect to remove
your current mercury thermometers from you house, please observe
the following hazardous waste instructions. Do not toss your mercury
thermometer into the garbage. You can take your thermometer to a
household hazardous waste facility or look for local "exchange
programs" in which old school glass mercury thermometers are
being exchanged for new digital thermometers.
