Cold Hands, Cold Heart, Are Bodies Cooling Down?

The classic 98.6 degrees Fahrenheit has always been contested but authors of the new study say the figure is probably right and human body temperatures have actually decreased over time. (Rtuťový teploměr)

Health Editor’s Note: Statistics would point in the direction that the human body is cooling down.  The average body temperature is no longer 98.6 degrees F. In subsequent studies over the years, the average body temperature is falling and is now about 97.9 degrees F.  Any ideas of why or how this is happening?…..Carol

Human Body Temperature Is Getting Cooler, Study Finds

By Brigit Katz/

In 1851, a German doctor named Carl Reinhold August Wunderlich took the temperatures of some 25,000 patients in the city of Leipzig and concluded that the average human body temperature sits at 37 degrees Celsius, or 98.6 degrees Fahrenheit. Though variations are known to exist from person to person, Wunderlich’s standard remains a benchmark for medical professionals today. But a new study published in eLife suggests that in the United States, at least, average temperatures are going down—a trend that can be observed in medical records spanning more than 150 years.

Previous research indicated that Wunderlich’s average may have run a little high. In a 1992 study of 148 patients, for instance, scientists at the University of Maryland measured an average temperature of 36.8 degrees Celsius, or 98.2 degrees Fahrenheit. More recently, a 2017 study of around 35,000 British patients found that the mean oral temperature clocked in at 36.6 degrees Celsius, or 97.9 degrees Fahrenheit. Some experts concluded that Wunderlich’s measurements had simply been inaccurate. But according to the new paper, authored by researchers at the Stanford University School of Medicine, human bodies are actually cooling.

The team looked at three large temperature datasets from three distinct periods. The first was compiled from medical records, military records and pension records of ….Read More:

  1. If we assume that body temperature is the result of thermal energy released when ATP (Adenosine triphosphate) is converted into ADP (Adenosine diphosphate) within each and every normal respirating cell, it would be logical to assume that there is some mechanism causing a reduction in the initial ATP which is available for conversion, either in the cell’s mitochondria(power source), or the appropriate cell receptor. The precursor in the bloodstream is glucose.
    We know there is an obesity, insulin resistance, pre-diabetic, type2-diabetes epidemic in the US, and other nations consuming a high carb diet. High carbohydrate consumption throughout the day spikes insulin levels, and keeps them there. Under chronically elevated insulin conditions, proper insulin signaling doesn’t take place, sitting off glucose availability for cellular energy conversion. Less energy conversion begets less thermal reaction and transmission, which in turn results in a diminished average body temperature.
    Just my two cents.

    • A study done comparing body temperatures of different strict dietary groups might shed light on this; compare average body temperatures of a group doing a strictly Keto, vegan, typical Western, etc.

    • So fat ass Americans aren’t good-looking aka… hot.

      Maybe we’re devolving, turning reptilian. Damn…

      Trump & Alex Jones were just fearmongering hysterical paranoia & going for the Evangelical vote, but then they’d actually be right about demon Hillary! 😂

      (Not that reptilian is synonymous with demon, to any reptilian race out there! #Woke😁

    • Sugar is more addictive than cocaine. It’s been shown that unhealthy bacteria, that metabolism sugar in the gut, can hack into the vagus nerve, which runs from the gut to the brain, hijacking it and sending signals to crave sugar. In that sense, we are devolved.
