Goodbye to normal body temperature? Studies show that value is different for each person

The idea is that body temperature normal is a certain value deeply rooted in the popular consciousness, but a study of Stanford University Turns out that’s not entirely accurate.

Research has shown that body temperature varies significantly between people and even throughout the day, depending on factors such as Age, gender, weight, height and time of day.

This means that what is considered a “normal” temperature is set 37°C for 150 years, and then fell to 36.6 degrees Celsius, It is more flexible than before.

According to the study led by Julie ParsonetteProfessor of Medicine and Epidemiology at Stanford Medicine, The average body temperature of the population has changed.

while standard 98.6 °F (37 °C) was established by German physician Carl Reinhold August Wunderlich in the 19th century.Current research indicates that average temperature worksI dropped to about 97.9°F (36.6°C).

This value was derived from an analysis of more than 600,000 oral temperature measurements taken between 2008 and 2017 from patients treated in the Stanford Health Care System.

The Stanford research team analyzed these measurements using machine learning algorithms to remove the data detected from diseases Factors like time of day, age, gender, weight and height,

They found that body temperature naturally fluctuates between 97.3°F and 98.2°F (36.2°C and 36.8°C).

Furthermore, he also observed that the temperature is lower in the morning and it happens highest around 4 pmThe temperature is lower in men than in women and the temperature also decreases with age.

The decline in average body temperature in the United States, which has been about 0.05°F per decade since the 19th century, is due to Improvement of living conditions and general health of the population.

These improvements have reduced long-term falls in people, which may explain the drop in body temperature. According to the researchers, this variation reflects differences in health between today’s population and those of an earlier time, when the 98.6°F standard was developed.

definition of fever It may also vary depending on each person’s normal temperature range.

Traditionally, a fever is considered when the temperature exceeds 100.0°F or 100.4°F (37.7°C or 38°C).

However, Parsonnet and his team suggested that, by not considering individual differences, Some infections go undetectedAs was the case with Parsonnet’s mother-in-law, who was not diagnosed with a serious heart infection because her temperature did not reach the traditional fever threshold.

As has been discussed for some time in other areas of medicine, this study highlights the importance of More personalized approach Of patients.

Knowing a person’s normal temperature range can help detect diseases earlier and more accurately. Researchers hope that its use personalized parameters Measuring body temperature makes it a more accurate vital sign, allowing deviations that may indicate the onset of an illness before other obvious symptoms appear.

This may have important implications for Improve early diagnosis and treatment About various health conditions.

new vision of temperature variability Body suggests that each person has his or her own range of normality, which is influenced by many factors. This more personalized approach could revolutionize the way vital signs are used for medical diagnosis and highlight the importance of considering the uniqueness of each individual in their health care.
