How many heartbeats do mammals have in their lives?
Does a mammal have 800 million heartbeats in its lifetime? This statement is not accurate.
"mammals have 800 million heartbeats in their lifetime."regardless of species and size, in their limited lifespan, the number of heartbeats is basically about 1.5 billion." all mammals have heartbeats of nearly a billion. it's just that it took mice 750 days and elephants 75 years. I don't know if you've ever heard of that.
how much is the average heartbeat of mammals in their lifetime? is it true that all kinds of animals are the same? In fact, this figure is not as accurate as some cold knowledge suggests. But in a sense, there does seem to be a link between heartbeat and longevity. Usually the smaller animals have a faster heartbeat and metabolism and have a shorter lifespan, while the larger ones have a slower heartbeat and a longer lifespan.
scientists have counted and estimated the heartbeats of many kinds of mammals, and it is found that the average heartbeats of all kinds of animals are about the same order of magnitude (on average, 700 million to 800 million). But there are still a lot of fluctuations, just about the same order of magnitude). However, there is one very obvious exception-- we humans, because we now have a much longer life expectancy, the estimated total heartbeat in a lifetime is much more than that of other animals, not 800,000,000 or 1.5 billion. It can reach 3 billion.
the heartbeats of large and small animals are usually much worse, with mice beating 600,700 beats per minute and elephants only having more than 30 beats per minute. The common explanation for this phenomenon is that small animals have a relatively large surface area and lose heat more quickly, so high metabolism is needed to maintain body temperature stability, and fast heartbeat is also a product of high metabolism.
but there are exceptions, such as the exotic naked shore mouse introduced before, which is obviously small, but its heartbeat is much slower and its life span is much longer. More reading: nude Mouse: I'm ugly, but I'm legendary

as to why a fast heartbeat is associated with a short lifespan, there are opinions (and some experimental results) suggesting that a rapid heartbeat may be bad for heart health.
(within a safe range) can slowing down the heartbeat make people live longer? For healthy people who do not have heart disease, the answer to this question is that they do not know yet. However, regular exercise is very good for heart health.
