Fitbit heart data reveals its secrets

Monday, September 3rd, 2018

Fitbit has now logged 150 billion hours’ worth of heart-rate data from tens of millions of people, all over the world:

Fitbit Heart Data 1 Resting Heart Rate by Age

Fitbit Heart Data 2 BMI vs. HR by Gender

Fitbit Heart Data 3 Resting Heart Rate with Exercise

Fitbit Heart Data 4 Activity Effect on Resting Heart Rate by Age

Fitbit Heart Data 5 Resting Heart Rate with Sleep

Fitbit Heart Data 6 Activity vs. Heart Rate by Country

    Those animals of the mammalian species it has been observed should live about 1 billion heart beatsed on sixty heart beats per minute], across the board, regardless of species. The average human by such a measure should live about forty years by such a criteria and calculation but now the average life expectancy of a person in the developed world is twice that. What does that say?

  2. TRX says:

    I take my blood pressure and heart rate every morning. The heart rate is typically in the low 50s, sometimes high 40s.

    I’m way out of the norm for every listed category, it seems…

    Oddly, when I was in junior high, we had to take and log our heart rates every day for a week in science class. It was usually 100-120 then.

    Anyone who wears one of these things is in a self-selected group. Usually a body-Nazi (the ones who like to explain to everyone else how they are more fit than YOU are). Or the less obnoxious gym-rat or road-rat who just likes the rush.

    This is NOT representative of the general population. (To be PC: Worldwide.)

    The Captain,

    I think that the number of fatties trying to be thinnies might balance things out.

    Thing that concerns me, though? That vast middle ground of “don’t give a damns” and those with no reason to care, in other words, those who are just naturally healthy. All too much of our data about human health and behavior stems from studying the outliers and not the center-of-mass. You don’t have a problem, why bring the issue up?

    FitBit data might be useful, but I think you would have to do some truly random selection, and then probably take steps to ensure that those random sample subjects actually used the damn things.

    I think that when (and,if…) we ever manage to wire the general population for sound, so to speak, there are going to be some huge surprises in terms of what we considered “normal”… And, really isn’t. Both in terms of physical norms and behavioral.
