The results of scientific research show that the life span of mice is extended by 40% in a low temperature environment
The recent weather changes make it feel like winter is coming, and the cold temperatures make it hard to wrap up in heavy clothing. But at the same time, Chinese scientists have discovered an astonishing phenomenon: the low temperature environment may be able to prolong the survival period of organisms, reaching a 40% increase.
A team led by Principal Investigator Professor John Speakman conducted the study. They selected mice as experimental subjects and divided them into two groups, placed at a low temperature of 20 °C and a high temperature of 325°C environment and monitor their health status daily until natural death.
Surprising results showed that mice had a 30% shorter lifespan at high temperatures, while mice with low temperatures had a 40% longer lifespan. The findings have been published in the journal Nature. Judging from the experimental data, if this result is translated to humans, it is equivalent to the average life expectancy soaring from 77 years old to more than 100 years old. Professor John is looking forward to this, and he believes that this experiment opens new doors for us to explore the potential factors of longevity.
However, in an era where everyone can live to be 100 years old, can it come true just by "freezing it"?The answer to this question is clearly no. At present, this study has only been conducted at the animal level, and no clinical studies have been conducted, so its applicability in humans is unclear. But interestingly, in the analysis of laboratory animals, the focus was also again on the cellular level.
Exploring the mechanisms behind low-temperature life extension is closely related to cells.
Cells are known as the basic unit of living organisms, and as we age, cells in the human body also age. However, aging cells do not disappear automatically, on the contrary, they will remain and accumulate in the body until they reach a certain level, affecting the body's vitality, sleep, etc.
In short, cellular aging is the beginning of aging in the body and the root cause of aging problems, so it is recognized as one of the 12 indicators of aging. It is obviously very difficult to slow down cell aging by relying solely on low temperatures. In addition, keeping a low temperature for a long time can easily cause problems such as colds and fevers, which makes the long-term maintenance of this method more complicated.
However, based on the cellular mechanism, some more mature scientific and technological achievements have also been discovered, which can reduce the proportion of aging cells and activate cell vitality in a more scientific and convenient way. For example, the core molecule of "Shi Ji Na" has been supported by clinical data from Harvard Laboratories and the University of Tokyo, and is considered by the academic community to be one of the most promising research directions in biological sciences.
According to the relevant study, a 30-day intervention trial invited middle-aged participants with an average age of about 50 years. The results of the experiment showed that with the removal of aging cells, skeletal muscle, hearing, grip strength and other indicators returned to the state of youth.
The promotion effect of scientific research has also attracted the attention of the outside world. Under the promotion of Beijing and Dong, 85% of Shi Ji Na's turnover comes from middle-aged men between the ages of 35 and 55, "After all, we may not know much about the mechanism, but we believe that scientific data is always correct." And it's easy to take. Mr. Cai, a 42-year-old from Shenzhen, said.
According to the data of CITIC**, the relevant market is expected to form a scale of 100 billion yuan within 5 years, bringing new impetus to the domestic economy.
In addition, according to David, a tenured professor at Harvard Medical School, there are countless laboratories around the world that are conducting relevant research. Not only the discovery of cellular mechanisms, but more and more fields are gradually becoming associated with it.
For example, a study published in the journal Cell clearly divided the 12 major indicators of aging, including genes, epigenetics, telomeres, mitochondria, and more. Bezos, the former richest man in the world, invested 20 billion in research on genetic reprogramming and successfully restored the 114-year-old cells to their infancy state ......
Advances in medical knowledge are revealing the truth of aging in front of us. Perhaps in the near future, we will indeed be able to usher in an era where everyone will live to be 100 years old, and this is the most exciting part of the unknown.
