Human body temperature 37 ° C has become history!The lower the body temperature, the worse the immunity, is it true?
Come first to make a choice questions ↓
Since the epidemic
The body temperature has almost become what everyone does every day
But some people discovered
The body temperature is always a little more at 36 ° C
None has reached 37 ℃
Why is this?
In 1851, Dr. Wunderlight in Germany
Millions of body temperature measurements were performed for the subjects in Leipzig, Germany
And calculate the normal value of the human body for the first time
—— 37 ℃
Since then
Body temperature has always been used as a key life signs for judging health status
However
In 2020, researchers at Stanford University in the United States discovered
In the past more than a century
Human normal body temperature is decreasing
Researchers have been analyzed since 1860
More than 677,000 part of the collective temperature data
Compared with the end of the 19th century
The body temperature of men and women was reduced by 0.59 ° C and 0.32 ° C, respectively.
Why does the temperature of the human body decrease?
At present, there are three main speculations in the scientific community:
① Modern hygiene conditions have become better
In the past, because of poor hygiene conditions
Therefore, the human body is often infected with inflammation
Fast metabolism
So there are more calories generated
② The modern environment tends to be “constant temperature”
There are air conditioners in summer, and heating in winter
Improvement of external environment
Makes the human body from using too much energy to adjust the temperature
③ change of population structure
Physical temperature will be affected by age and gender
With the extension of the life expectancy of modern people
There are more and more elderly people
After the age, the body’s metabolic rate will decline
Temperature will be slightly lower than youthful adults
And adult female subcutaneous fat
Small calories
Adding the effects of sex hormones
Menstruation and pregnancy will be a little higher than normal
Therefore, women’s body temperature will also be about 0.3 ° C higher than men
According to 2021 population data
The current ratio of men and women in the world is 101: 100
But most areas still show more men than women
Japanese expert Ishihara Real “Come from the Come from the Come” mentioned:
When the temperature is 35.5 ° C
Cancer cells will breed a lot;
And when the temperature is 39.6 ℃
Cancer cells will disappear in large quantities;
Body temperature every 1 ℃
The immunity of the human body decreases by 30%;
There are a large number of examples in the book indicating:
High body temperature can significantly reduce the symptoms of heart disease, depression, cancer and other diseases
Not
Will decreased body temperature really lead to a decline in immunity?
Theoretically
Decreased body temperature will indeed cause immunity to decrease
Because of the low body temperature, the basic metabolic rate is also low
When the efficiency of the white blood cells decreases and the blood flow becomes slower
Even if bacteria, viruses, etc.
The reaction will also become slow
Pay attention when the body temperature
The normal temperature range of different parts is different
The oral temperature is 36.3 ℃ ~ 37.2 ℃
The temperature of the armpit is 36.1 ℃ ~ 37 ℃
The anal temperature is 36.6 ℃ ~ 37.5 ℃
The temperature in the ear generally does not exceed 37 ℃
The forehead temperature does not exceed 37.5 ℃
In normal body temperature range
The higher the body temperature, the stronger the immunity
Because the higher the body temperature
You can activate more immune cells
So as to better eliminate the pathogenic microorganisms invading the human body
It plays a role in protecting the body
But pay attention to
The body temperature is too high, too much value is also harmful
Clinical
It is a fever if it exceeds the normal value of 0.3 ℃
It is a fever reaction of immune cells to eliminate the pathogenic bodies
Normally
Fever is good for activating the body’s immune function
But if the body temperature continues to rise to 38 ℃
There will be multiple organs to participate in cooling, such as the sweat glands
When it reaches 39 ° C, the sweat glands may be on the verge of failure
Let the body appear a series of stress reactions
Extract oxygen consumption, faster heartbeat, increased heart output, etc.
For patients with heart disease
This will cause a lot of burden, and may even cause myocarditis
If it is not treated in time, the body temperature reaches 40 ℃
The brain will become a loss of this
It is easy to affect the nervous system
Makes symptoms such as unswerving, tiredness, drowsiness and other symptoms;
And reach 41 ℃
The body temperature is generally over -the -standard
At this time, it is serious to endanger life
What should I do if I find that I have a low body temperature for a long time?
Try the following methods
Come to help heat up
Exercise not only keeps the body good vitality
Enhance cardiopulmonary function
It can also enhance muscle strength
Make the energy supply in the body sufficient
Exercise
Human blood circulation speeds up
Immune cell white blood cells are more active
Can detect and kill pathogens faster
So it is recommended to reduce long -seated
Choose rope skipping, run, squat and other exercises
Warm your body
Fat is the “insulation layer” of the human body
Can help maintain body temperature
It plays a role in resisting the cold
Therefore, there is no need to over -lose weight
Keep a moderate body fat content
Only to help maintain normal body temperature
For adults
Men should keep the body fat rate at 15%~ 18%
Women should keep the body fat rate at 20%~ 25%
Long -term in an environment where air conditioners are cool
It may reduce the sensitivity of the hill brain temperature adjustment center
The ability to regulate temperature decreases
Caused body temperature decrease
Human body temperature is not a fixed value
If the long -term body temperature is lower than the normal value
Be wary of diseases such as hypothyroidism, chronic heart failure, anemia, malnutrition and other diseases
Causes the pathological temperature too low
