Sleep controls the time of nature?

Many of us wonder if we have slept deep enough and enough time, some want to spend more time on sleep, while others want to reduce it.

And we think that being awake at 2 am is not good for health. But is that right?

In fact, no one knows this. Scientists have yet to explain why animals need sleep and each animal type has different sleeping habits.

Why do lions spend 15 hours a day sleeping, while giraffes need only 5 hours? How can migratory birds sleep when they have to fly continuously for many days? And why do people go to sleep more and more?

The August issue of Neuroscience had an explanation of this issue. This article quotes Jerome Siegel, a professor of psychology at the University of California, Los Angeles. He thinks sleep is also a way of using animals' time and this helps them hide more safely. According to that explanation, the sleep difference of species is simply an adaptation to different environments.

In life, we spend a third of our time sleeping, and this seems unreasonable. Scientists often call this the biggest mistake of creation. But Professor Siegel, who is also the head of the neurobiology department at Los Angeles Veterans Health Center, said: ' If sleep is a mistake of creation, then the awake is a bigger mistake '.

In the field of sleep research, most experts disagree on any hypothesis given, and Professor Siegel's hypothesis is no exception. Some experts object that when animals sleep, they will lose their vigilance and sleep to serve other essential functions of the body. Some argue that sleep is a time for the brain to consolidate memory, others consider sleep as a factor in restoring damaged neurons.

According to my hypothesis, sleep is a time for the body to ' maintain ' neurons, 'said Clifford Saper, a professor of neurology at Harvard University. But he added, his theory and Professor Siegel are not the only possibility.

Professor Siegel said that sleeping animals are not as harmless as we think. Because sleep, their hearing becomes more sensitive to any kind of sound. This explains why we can be awakened by very small noises.

It is also studied that the alertness of tiger fish when sleeping as well as when they are awake is the same.

Brown bats are considered by most scientists to be ' lazy ' mammals. They sleep for 20 hours a day and only spend 4 hours to hunt at dusk. " The reason these animals spend so much time sleeping is because sleep helps their bodies save energy and is able to see and fly better every time they go hunting, " explained Professor Siegel.

For humans, the quality of sleep changes gradually with age. Children need plenty of sleep and deep, while adults need only 5 or 6 hours of sleep each day. ' This is a matter of biological balance, children need long and deep sleep as a condition for physical development and brain development ' - Professor Siegel said

In short, even if the sun does not grow or our 24 hours are daytime, animals still need to sleep. And depending on the animal species, the awakening time may or may not depend on the time of sleep.

No one can say that a good sleep is unnecessary or sleep problems do not exist. But according to Professor Siegel's hypothesis, insomnia may not be evidence of body disorder. If sleep has become the most effective time management tool in nature, the fact that you wake up at 2 am is simply because you need to complete something. So the simple thing you need to do then is to get out of bed and start working.
