The exact answer is 25 years.

Besides, the Panda bears are generally carnivorous creatures that eat bamboo. Bears are not considered friendly animals but rather lonely creatures. They are, however, interactive while mating or nursing their pups, as is obvious.


Bears are carnivorous animals of the Ursidae family. They are classed as caniforms or carnivorans that look like dogs. Although only eight species of bears exist, they are ubiquitous, inhabiting a broad range of habitats in the Northern Hemisphere and, to a lesser extent, the Southern Hemisphere.

The bears can be diurnal or nocturnal. Bears are thought to have a keen sense of smell, and despite their size, they are well suited to climbers and swimmers.

What is the average lifespan of a bear?

Species Of BearLife Expectancy
North American Black Bear18 to 20 years
Brown bear20 to 30 years
Polar bear22 to 25 years
Giant Panda15 to 20 years
Asiatic black bear20 to 25 years
Andean Bear18 to 22 years
Sloth Bear30 to 35 years
Sun Bear25 to 30 years

Humans have found eight different species of bears. These bear species are found worldwide, including in North America, Europe, and Asia.

On the other hand, the polar bear is the only large bear species with a habitat in the southern hemisphere.

The North American black bear, as the name suggests, is mostly found in North America. Male and female bears achieve the full size and are ready to procreate between the ages of 5 and 8. They have a lifespan of 18 to 20 years.

  • The brown bear, often known as the grizzly bear, is projected to live for 20 to 30 years.
  • Polar bears are most prevalent in Antarctica and the Arctic, where they have lived for 22 to 25 years.
  • The Giant Panda, which lives in China and eats bamboo, has a life expectancy of 15 to 20 years.
  • The white spots on the chests of the Asiatic black bear, which has a life expectancy of 20 to 25 years, help to identify it.
  • Andean bears are located in the Andes Mountains and live for 18 to 22 years.
  • The sloth bear is expected to live for around 30 to 35 years.
  • The sun bear has a life span of 25 to 30 years.

Why do bears live such long lives?

Bears have been around for as long as people have. Because they have been on the earth for so long, their descendants have been able to adapt to shifting surroundings. This has increased their chances of living longer lives.

With the arrival of the nineteenth century, astounding advances in science and technology were made. Aside from human health studies, scientists also conducted the animal study. They recognized the causes of bear ailments and the methods for curing them.

This aided in preventing infections and epidemics, which would otherwise be common. In addition, due to improved medical care and attention, bears’ average life expectancy has grown.

Another factor contributing to bears’ increased life expectancy is the establishment of institutions such as zoos and animal conservation centers. These facilities include all the facilities needed to care for the bears properly. As a result, this technique has a favorable impact on bears’ normal life expectancy.

The introduction of anti-poaching legislation by many nations has also aided in protecting and providing safe havens for bears. Poaching and hunting wildlife, as is widely known, pose a significant danger to their survival. Countries have ensured that they do enough to keep their habitat safe to call home by enacting tough legislation.

The Most Common Natural Causes of Bear Death

Bears that live in the wild can die from several natural and manmade causes.

Some of the most common natural forms of death for bears include drowning and other natural disasters, starvation, infections, and injuries, dying from wounds inflicted during fights with other bears and dying as a result of predation, such as male bears killing and eating cubs and black bears being killed and eaten by grizzly bears.

Intriguing research published some years ago suggested that many factors that eventually contribute to a bear’s mortality in the wild begin with tooth disease. When a bear develops a severe cavity, it may frequently lead to infection and excruciating discomfort.

That one bad tooth can set off a chain reaction of negative consequences, such as a bear being unable to eat as much as it needs to survive or not being able to consume its normal food sources.

Therefore, it causes the bear to become progressively weaker, resulting in less fat reserves, less energy to search for alternative food sources, and less strength to defend itself from other bears. So let it serve as a lesson to take good care of your teeth!


Bears have a life expectancy of about 25 years. They are, however, eight in number, and each has its average life expectancy. In addition, various species live in different geographical areas and have varied physical characteristics.

Bears have developed and adapted to their changing natural surroundings over time. The advent of science and technology has greatly increased their chances of living a long and healthy life. Aside from that, the establishment of animal conservation facilities and the implementation of protective legislation have enhanced those odds even more.
