What is "normal " temperature? Mine is usually about 36 but sometimes 35. I have low blood pressure around 55 but have always had that even before being diagnosed as hypothyroid. I take 125 levothyroxine daily an increase of 25mg over last two months. Due to have blood test soon.
Thanks
Janeamber,
Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6°F (37°C). ... A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.31 Jan 2015

A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.

For a normal reading, your blood pressure needs to show a top number that's between 90 and 120, and a bottom number that's between 60 and 80. When both your systolic and diastolic numbers are in these ranges, you're considered by the American Heart Association (AHA) to be within the normal range for blood pressure.8 Jun 2016

Thank you. I am a bit low but I think normal for me - believe me when I say I'm not a trained athlete ha ha. Funny I can have a low temp but still get boiling hot, flushes still I think !!
From my experience and from what my latest dr has said, Low blood pressure and heart rate also identifies with Hypothyroidism. My resting heart rate was in the low 50s before treatment, it improved with medication and with T3 it increased even more. BP increased with medication as well.
Thanks I have been thinking about t3 after reading all the posts will wait for next blood test and see what everyone on here thinks. I don't hold out much hope of getting it from gp but will ask if they would monitor me
T3 made a huge difference for me
Did you feel more motivated? Did you lose weight?
Body temperature also varies depending on how measured.
Some authorities say that blood pressure isn't OK if pulse pressure (big number minus little number) is over 50. That means 120/60 gives a pulse pressure of 60 which is too high, despite both numbers being in their respective ranges.
Do not talk while measuring blood pressure.
[ Numbers corrected - I mistakenly put in the wrong number for the little number.

I'll ask for my no to be taken next time I go and use the formula you mention. It's all so confusing all I know is I feel so down, no motivation fat and horrible. It helps to come on here and know I'm not alone
this is interesting. mine is always 20-40 apart!!!! i always wondered why 120-80 is considered normal.
Brain fog affects my arithmetic, too 
120 - 80 = 40
Messed up my typing! I have corrected my earlier response.
Also, the Wiki article on pulse pressure seems not too bad:
Different information is given about temperature and what is normal and what is not
normal. 36 c is meant to be normal. However there must be many people who have subnormal
temperature or a normal temperature but they may still have an infection which needs
treating. Most pharmacy advisors might say if your temperature is over 37 for a couple of days
wait and see - but if you have diabetes or a thyroid disorder you might have a bacterial infection
which may not present with a higher temperature.
Most doctors will wait and see until your temperature rises before treating you as they will say you have a virus. This is scary as bacterial infections may be overlooked - the policy of cutting down
on the use of antibiotics may be questioned by anxious parents and people who don't follow the norms according to government guidelines.
