'Life lies in the cold'? The Chinese Academy of Sciences reveals that low temperature environment reduces metabolism and prolongs life by 40%
Scientists have always believed that the body temperature of a healthy adult should be 37°C, but researchers at Stanford University have found that since the 20th century, the basal body temperature of the human body has dropped "naturally", and is now more inclined to 36.6°C. In our traditional concept of health preservation, the elders often teach us to "drink more hot water and wear more clothes". It seems that avoiding cold and maintaining body temperature are the foundation of health.
Recently, a study by the Chinese Academy of Sciences has surprised everyone—researchers have found that lowering the body temperature of warm-blooded mammals can extend their natural lifespan by 40%! In this regard, some netizens can't help but make such a joke: Should we hide in the refrigerator for this?
1 The Chinese Academy of Sciences has newly discovered that "cold" stretches life expectancy by 40%
Not long ago, Professor John Speakman of the Chinese Academy of Sciences and several researchers discovered that although high body temperature can promote metabolism, low body temperature may have a better impact on life expectancy. The related research was published in the sub-journal of "Nature".
In the experiment, the scientists ensured that the experimental mice were in the same living and dietary conditions, and then divided them into two groups. The ambient temperature of group A was 20°C, and the ambient temperature of group B was 32.5°C. The scientists were also "intimate" Cool them down with a fan so they don't suffer too much. The experimental results showed that the average lifespan of the mice in group B was shortened by about 30%, and various physiological indicators aged faster; while the lifespan of the mice in group A was even stretched by 40%, and their physical indicators degenerated more slowly.
This study shows to some extent that hypothermia may be one of the effective means of affecting lifespan, and this also brings thinking to scientists in the field of life. They speculate whether this principle is also applicable to the human body, and whether we can rely on it. This achieves a jump in lifespan?
2 Cold temperatures slow telomere loss, thought to be key to life
Compared with artificially creating a low-temperature environment in the above-mentioned experiments, there are actually many cases of low-temperature long-term survival in nature, such as six-star sponges, which are in the deep sea at around 0°C, and their growth and development are slow, which also leads to their slow attenuation. It can live more than 15,000 years, and it is similar to turtles that live in water for a long time.
If metabolism is an important factor for low temperature survival, then the "groundhog" experiment at the University of California reveals the reason behind it from another angle. The researchers found that genetic aging in groundhogs is basically equivalent to pressing the "pause" button when they hibernate. When their body temperature drops to a certain level, their physiological indicators such as telomeres and mitochondria are also better protected.
We all know that scientists are very interested in the study of telomeres, which are also considered to be the key to the survival of life. In the research results published in the well-known academic journal "Aging", Israeli scientists through the "high-pressure inhalation of pure oxygen" experiment, the subjects' telomeres were extended by an average of 20%, aging cells were reduced by 37%, and the overall functional level was equivalent to being 25 years younger . In Harvard Professor David's experiment, the endogenous coenzyme I (the core substance of WLife) was used to stretch telomeres and rejuvenate mitochondria. The results also found that the aging-related indicators of the experimental group returned to a young state.
In fact, the research on telomeres and mitochondria has gradually matured, and three scientists in related fields have even won the Nobel Prize, prompting relevant achievements to be put into practice after completing clinical experiments. Wright Weijian team developed "WLife" based on the relevant mechanism of action to slow down the rate of decline in body functions, which has caused considerable repercussions at home and abroad.
It has been more than 50 years since James Bedford, the former richest man in the United States, received "human freezing" at low temperature in 1967, and he still hasn't woken up. Under such a precedent, the impact of low temperature on life has naturally been questioned, or is low temperature only suitable for "keeping fresh"?
3 The life expectancy of human beings has doubled, and we are already on the "eve" of victory?
At present, the average life expectancy in China has reached 77.4 years, compared with 34.9 years in the 1950s, a double increase in comparison. Coincidentally, Stanford University research found that human body temperature has been declining in the past 200 years, which means that there may be some relationship between the two.
In addition, in addition to "physical cooling", scientists have also discovered that body temperature can be lowered by reducing the intake of "calories" in the diet, thereby reducing some excess body loss. Melatonin and "WLife" secreted by the pineal gland of our brain when we fall asleep at night can also achieve similar effects to lowering body temperature based on other mechanisms. The latter has gained a large number of loyal high-net-worth fans of Yidong and Tmall by virtue of many scientific research experiments and evidence, as well as phenomenal aging control performance.
Today, with the advent of many scientific research achievements and the blowout of science and technology, scientists believe that we are already on the "eve" of a leap in life expectancy and quality. Perhaps it won't be long before more mechanisms behind body temperature regulation will be discovered, and advanced cutting-edge technologies will be better popularized to benefit mankind.
