    Could someone point me towards whatever studies or evidence Dr. Peat uses to arrive at his recommended pulse range?

    He mentions that "Healthy and intelligent groups of people have been found to have an average resting pulse rate of 85/minute, while less healthy groups average close to 70/minute." Does anyone know the source for this?

    It seems like a fundamental aspect of Dr. Peat's health advice and I would just like to find some grounding for it, before I consider using it as a goal.

    Reference: You seem to be quoting Peat from:


    Past that, I don't see that Peat had a reference, nor that he used 85 as a recommendation.

    I don't think a pulse rate should be a "goal". At the very best, it might be an indicator, when measured in the same individual over time, on waking, before and after meals, etc. And it, by itself, is of little value. Peat talked of measuring it at different times while also recording temperature, etc.

    I have a resting pulse that's often in the 50's and it doesn't make me think I'm unhealthy at all. If I found it to be in the 80's however, after being below 60 my whole life, I'd become very concerned. It's personal data like this and reading other health advisors that cause me to give Ray Peat a ton of latitude in his statements. He can say whatever he wants, and I will always consult other opinions before I follow what I think he might be saying.

    Some discussion from a transcript of an interview:

    HD: Ok. How about, if the temperature doesn’t reach 98.6, or the pulse never gets over 70 (in the mid-afternoon) ?

    RP: Well, people have their chronic adaptation, and some people can stay very well at these average numbers. But, on average, people have the greatest ability to resist stress and recuperate from injury if their temperature is a little above average, and their pulse rate is a little above average. So, your health can be very good for most of your life, but you will have more resilience if your metabolic rate is higher.

    "The late Dr. Broda Barnes introduced the basal temperature test as an easy way to determine adequate thyroid function. It’s important to do an oral temperature test. The oral temperature is measured with an oral digital thermometer after arising. Women should do this during their menses to ensure missing the rise of temperature during ovulation. The morning oral temperature after arising should be 98.0 degrees F. It should then rise to 98.6-99 degrees F between 11 am and 2 pm and the resting daytime pulse should be around 85 beats per minute. The national average is around 72. If your pulse is less than 80, you may have an underactive thyroid (however a hypothyroid person with high adrenalin can have a pulse of as high as 150). Babies have a pulse greater than 100 until around the age of eight years when the pulse slows down to around 85. Dr. Peat says that the idea of a slow pulse being healthy is folklore. Thyroid needs increase during the cold, dark winters and decrease during the warm summer days when there is more sunlight. In addition to the seasons, any kind of stress hinders thyroid function.” -Lita Lee, PhD

    This is the one place I don't disagree with Ray peat but am kinda disappointed since I've had a life long fear of a fast heart beat.

    What I don't understand is: Should we take our pulse while standing, sitting or lying down?

    I know this is an old thread, but I'm also interested in the source for Peat's quote. I agree with it, and I've backed it up with my own measurements, but I sometimes get into debates with people about this and would be nice to have the research to back it.

    I’ve looked for evidence. There is such a strong prejudice that “lower pulse = greater fitness” that studies and such are not done.

    However I will say that you can’t have a euthyroid temperature without having a HR in the mid 80s in my experience.
