185 1 year, Carl Wunderlich, a doctor from Germany, collected the temperature data of 25,000 patients, and determined that the normal temperature was 36-37℃ for the first time. This data has continued to this day. However, in recent years, many scientists believe that the body temperature is decreasing.
65438On October 7th, 2020/KLOC-0, Julie Parson, a professor at Stanford University School of Medicine, and her team released a research report. The report shows that since19th century, the average body temperature of adults has been declining continuously. In less than 200 years, the adult's body temperature dropped by 0.4℃, and now the body temperature is from 18566.
When we don't know, the body temperature of 37℃ has already become history.
Caption: The natural body temperature of human beings has a downward trend in recent years. Hypothermia is not a good thing! Will increase the risk of infectious diseases from Ebola virus, SARS virus, MERS prototype virus to the recent outbreak of COVID-19, all have one thing in common: it may have originated from bats. However, why can a bat that has been poisoned by all kinds of drugs be safe and sound? Scientists have found that bats usually have a body temperature of 40℃ or even a little higher, which makes them a "long-term fever".
The process of human fever is actually the process that the immune system works to kill viruses and bacteria, and the body temperature of bats is as high as 40℃, which makes most viruses unable to survive and stays on bats for more than 24 hours.
This also led to bats becoming super virus screening factories. They all carry viruses that are difficult for the human immune system to eliminate, and people can't solve them with a fever. The constant body temperature of human body is decreasing year by year, which aggravates this crisis to some extent.
Why does the body temperature decrease and the immunity decrease? Dr. Nobuteru Ishihara, a Japanese doctor of medicine, pointed out that the basal metabolism would increase by 13% for every increase in body temperature. On the contrary, the body temperature dropped by 65438 0℃, and the immunity decreased by 30%. Hypothermia may mean that your metabolic system is not very smart.
Blood and circulatory system are important tissues to maintain body temperature. When the body temperature is high, the blood flow rate will also be accelerated, so that white blood cells can find abnormalities in the body faster and make corresponding immune responses to remove pathogens as soon as possible. On the contrary, hypothermia will lead to the decrease of basal metabolic rate, slow blood flow and greatly reduce the working efficiency of white blood cells.
In this case, it is difficult for white blood cells to find foreign bodies in the body at the first time. Even if a foreign body is found, the reaction speed of other white blood cells will be very slow, which gives the virus an opportunity to make the body vulnerable to attacks by viruses and bacteria, thus causing diseases.
Hypothermia may bring cancer closer to us. In fact, white blood cells, as the main force of the immune system, can not only resist the attacks from external viruses and bacteria, but also monitor cancer cells in the body and kill them in time. Cancer has never been far away from us, and some scientists even believe that the increase of cancer incidence in recent years has a certain relationship with the decline of human body temperature.
According to scientists' calculations, if our body temperature drops 1℃, our immunity will be reduced by nearly 30%, which means that our immune system may miss nearly a thousand cancer cells every day, thus multiplying wildly.
Caption: If the temperature is too low, the risk of various diseases will increase! Lack of exercise leads to hypothermia in modern people! Only by increasing muscle mass can the body temperature be reversed. 170 years, the human body temperature dropped by 0.4℃, especially in recent 20 years. Scientists believe that the main reason is lack of exercise. With the development of science and technology, people seem to be more and more lazy.
Although basal metabolism has nothing to do with any external activities, it is a natural consumption when a person is idle, but muscle is the largest heating organ of the human body. Less muscle means lower body temperature and lower basal metabolism. And a person with high muscle content consumes more energy than a person with low muscle content, even if he does nothing.
When basal metabolism decreases, energy consumption will decrease and visceral fat will increase. Visceral adipose tissue can secrete more than 20 kinds of harmful hormones (or adipocytokines), which will cause vasculitis and weaken the function of insulin, thus triggering a series of chain reactions, leading to cancer, hypertension, diabetes and other diseases.
Muscle training from diet and exercise requires both exercise and diet training. In exercise and weight-bearing training, muscles need to bear the intensity of exercise that exceeds the load, so that cells are slightly damaged. Injured cells can produce a cytokine to start the mechanism of muscle repair and growth.
When the exercise intensity slightly exceeds the load and the muscle fibers are destroyed, the body needs to take protein to repair the muscles, help the muscles grow and build body components. If muscle training is compared to building a house, then protein is like a brick needed to build a house. Therefore, if people want to achieve the effect of fitness, they need to cooperate with a scientific diet and supplement enough protein after exercise.
Besides protein, we should also take enough carbohydrates, because about 60% of human energy is provided by carbohydrates, which can enable muscle builders to provide energy under moderate and high-intensity anaerobic exercise, and at the same time prevent the body from decomposing protein as an energy source and avoid muscle loss.
