The faster the heartbeat, the faster it ages, so why do bats have a 30 year lifespan with a thousand

Bats have many biological traits that merit scientific research, bats are the only mammals to fly, have ultrasound vision, are carriers of multiple cross-species viral pathogens, and have a long life in bats. The average lifespan of bats is usually up to 20 years, and in some bat species, even more than 30 years, the longevity of bats is mainly reflected in the following two aspects.

1.The lifespan of mammals is related to body size. The average lifespan of an African elephant is 70 years, a blue whale can live up to 90 years, and a mouse can only live for one to three years.

Humans are considered relatively long-lived animals, with four times longer than most mammals and twice as long as closely related primates adjusted for size. But bats have a relative lifespan far more than that, 8 times longer than mammals of the same size.

2.In homeothermic mammals, resting heart rate is inversely correlated with longevity. Even in studies with humans, an increase in resting heart rate is generally associated with a higher risk of death, such as in a large study of people with a normal high resting heart rate (80 to 99 beats per minute) who lived 40% shorter than those with a suitable heart rate (60 to 69 beats per minute).

However, once again, bats exhibit ultra-long lifespans, with a heart rate of up to 1000 when flying, and according to this calculation, the bat's lifespan is only 5 years.

Based on the above two facts, scientists have been using bats as an important model for healthy aging. In 2017, scientists discovered one of the secrets of bats' longevity, which is that bats can change their heart rate, adapting their bodies to work under extremely high and low energy loads. When bats fly, their heart rate is as high as 1066 beats per minute, but when bats are resting, their heartbeats periodically and dramatically slow down to 200-300 beats per minute, and this slowing is able to last for about 6 minutes, which can happen several times per hour.

At the end of the day, this adjustment can save 10% of energy.

In addition, another 2019 study found that hibernating bats living at extreme latitudes lived longer than bats living near the equator. This has to do with the ability of these bats to adjust to fluctuations in body temperature, and since high latitudes tend to require longer hibernation periods, hibernating bats are able to adjust their body temperature in time to reduce their metabolic rate during hibernation.

Because bats have small bodies and fast heartbeats that speed up their metabolism and make them more energetic, they will live a long lifespan.

Because the body structure of bats is different from that of humans, they need to fly violently, so their hearts beat fast, so they can live for so long.

Because the structure of bats is different from that of humans, and bats have a very high body temperature and a very long lifespan.

It may be that the cell differentiation is relatively slow, so that it is not easy to age, and the first organ of the body is more vigorous, that is, it can live for a long time.

Because the metabolism of bats is extremely fast, with super DNA damage repair ability, these are beyond the reach of many animals, bats in flight average daily energy consumption is more than 20 times that of ordinary mammals, which is also a long-term high fever in bats, and the reason why bats carry so many viruses but can still have a lifespan of up to 30 years is that they have a super immune system, the average body temperature reaches 40 degrees when not hibernating, and we all know that human fever body temperature rises by one degree, The immune system is doubled, which is why the bat's body temperature is in a state of fever for a long time.

That's because the shape of the bat itself is very special, so it is relatively normal to live for so long with such a frequency.

Although the heart rate of bats in flight is high, it spends 70% of the day resting, the heart rate will drop significantly, the body temperature will also drop to 38 degrees, and the bats at high latitudes will also hibernate in winter, their heart rate will drop to only 3-5 times per minute, and the body temperature will drop to 24 to 28 degrees. As a result, bats that hibernate at higher latitudes will live slightly longer than bats near the equator.

Bats are creatures that can coexist with viruses and have a strong genetic repair function, so they have a long lifespan.

This is due to the body structure of bats, so they are not affected by the heartbeat and reduce their lifespan.

Because bats have a very fast metabolism, they have a very strong DNA repair ability.

Why did the dinosaurs go extinct, all things exist have their reasons, and the extinction of all things is also a law, the earth is a hodgepodge, and symbiosis is the best. The result of natural selection. There are differences between animals, and they cannot be compared, this is the law of nature, the survival of the fittest.

Affected by this epidemic, more and more people are paying attention to bats. As a small animal that is extremely difficult to come into contact with in daily life, do you really know about bats? As the only flying mammal in the world, bats have survived on Earth for more than 50 million years.

There are also many species of bats, more than 1,200 species, all over the world. The small body greatly increases the rate of its metabolism in order to fly bats, and its heart rate is as high as 1,000 beats per minute when flying, and its body temperature rises directly to 40 degrees. At the same time, in order to adapt to the flying bat, a set of echolocation system is planned to help it better avoid obstacles in flight, we all know that bats are social animals, generally in dark caves, that is, a social life leads to the spread of viruses among bats.

If you want to study longevity, bats are not the first choice! On this planet, plants and certain fungi can be called the true kings of longevity! Some plants and fungi can live for tens of thousands of years!

As homeothermic mammals, the heartbeat is generally an order of magnitude! About 1 billion beats of the heart is basically scrapped!

It turns out that the bat is missing this part of the gene that is why it can live in harmony with the virus without getting sick. The immune system of bats, on the other hand, does not produce this devastating cytokine response when it is infected itself. The ability to fly is closely related to the longevity of bats, and in addition to avoiding viral infections, bats will not develop age-related diseases or cancers.

Bats are about the same size as mice, but rats only have a lifespan of two to three years. Bats live between 20 and 40 years. Researchers believe it has something to do with the bat's ability to fly.

So even if a bat has such a large heartbeat rate, its lifespan is not very related to this, and it has a lifespan of 30 years, which is an established fact.

The adaptability is particularly strong, and when eating food, they will always eat some relatively clean food, plus some body structures, the life expectancy will be particularly high.

This is related to the bat's own physique, the bat's metabolism is relatively fast, and it has a super repair ability. So the body is still quite good.

Mainly because bats have evolved a super immune system, so they still have 30 years to live.

Personally, I think the most important reason is that her own body structure is different from that of some animals, and its living habits are different from those of many animals, so even if his heart beats fast, their lifespan is not affected.

Bats are particularly immune animals, so they can survive very quickly with a heartbeat. This shows the strength of bats, which should not be taken lightly.

This is because bats need to fly vigorously, so their hearts beat very fast, and they have a long lifespan.

The heart of the bat beats very fast, and the bat is also very special because the bat is the only animal that has evolved the ability to fly among mammals, and its body temperature is relatively highIt has a large number of viruses sealed in its body, which can be said to be Pandora's box for humans, but it still has it despite its fast heartbeat

The bat's heart beats fast, not all the time, his heart beats more varied, when he is flying rapidly, the number of times his heart beats will reach 800 1000 times per minute, but this is when he is flying rapidly, the bat is addicted to his cave most of the time, only at night will go out to forage, the rest of the time is stationary, in the case of stationary, his heart beats only 140 300 times,When hibernation in winter, it beats about every minute

Although the bat is ugly, but he has basically no impact on human life, he does not conflict with human schedules, he chooses to go out late at night, during the day he is upside down in the cave, sleeping, at this time his heart beats very slowly, energy consumption is relatively slow,In the winter, he goes into hibernation, and his heart beats more slowly, so his heart life is not affected.

Because their physical fitness is very strong, and their physical function is very good, they have adapted to this heartbeat physique.

Because bats are animals that can coexist with viruses, and they also have strong repair capabilities, they will naturally live a long life.

The body structure of bats is amazing. Despite its small body, it needs a lot of heart support. Colleague it also has a long lifespan.
