According to a new study in Australia, northern koalas are sacrificing their sleep to have more sex. This can lead to their death.

Research has shown that males travel long distances in search of their females for sex, sacrificing sleep in the process.

Experts say that lack of rest could be the reason why male colts usually die after a single breeding season.

While the female koal lives up to four years and can give birth to children.

Christopher Clemente, a senior lecturer at the University of the Sunshine Coast, says: 'Male kools travel long distances for sex and their sexual desire is so high that they even sacrifice their sleep in search of female kools. '

His institute, in collaboration with the University of Queensland, conducted the research, which was published on Wednesday.

For this study, the researchers collected data over 42 days by placing trackers on wild male and female northern coots living on Grote Island, an island off the coast of Australia's Northern Territory.

Research has shown that some of these colts travel up to 40 kilometers a night in search of material.

Male koalas also appear to attract other blood-sucking organisms.

One possible reason for this is that they take less time to rest so that they can have more sex during a breeding season.

The researchers say that male koalas, like female koalas, are not as clever in avoiding other predators while searching for food and females.

"Prolonged sleep deprivation and associated symptoms after a breeding season make it difficult for male colts to recover and may be the cause of their death," said Josha Geshik, who led the study.

"They easily succumb to oversex, constant fatigue and lack of sleep, or get hit by cars or sometimes die of exhaustion."

He adds that this preliminary study underscores the need for more research to determine how sleep deprivation affects this species of animal found in Australia and Papua New Guinea.

"If male quolls sacrifice sleep for their own survival, then northern quolls may be an excellent model for studying the effects of sleep deprivation on the body," he said.

According to the Australian Department of Wildlife, the population of northern koalas in the country is about 100,000, but it is declining rapidly.

Due to the development and construction in different areas, there is a risk of losing their habitats and being hunted by stray cats. They are also threatened by wild frogs.
