Think about the sleep you usually spend casually.
What is sleep for living things?
All living things on earth live within 1 hours of the day.
Organisms have unique internal rhythms in order to adapt to their environment, and the optimal time for activity differs depending on the species.Humans have a 25-hour internal clock, so we reset it by one hour every day to match the 1-hour clock of the global environment.
The most effective way to reset is to expose yourself to light when you wake up.By doing so, the body clock will be synchronized with the earth time and it will be easier to work.
This rhythm is formed around 4 months of age.
Why do animals sleep differently?
There is a report that the time of the elephant and the time of the mouse were solved from sleep.
A large elephant sleeps for only two hours, but a small mouse sleeps for a long time.The relationship between energy expenditure per body weight and sleep time is inversely proportional. Larger animals consume less energy and sleep less, while smaller animals consume more energy and sleep longer.
Then what about humans?Since children are active in life activities for growth, they consume more energy and sleep longer than adults.
Why not stay up late?
It has been pointed out that children's sleep is nocturnal.It is believed that primates acquired the behavioral pattern of being active during the day and sleeping at night about 3800 million years ago.It's only been about 130 years since Edison's incandescent light bulb was invented, so our bodies, which are programmed to be active during the day, can't abruptly correct themselves when life becomes night-time.
Staying up late will cause you to wake up later and even go to bed later at night.Also, if you are exposed to light at night, it becomes difficult to synchronize with the earth time, which somehow leads to physical sluggishness, and in the morning you will feel like you are in a daze.A hormone called melatonin, which is secreted at night, is most secreted from 1 to 5 years old and supports healthy growth through sleep, but exposure to light at night affects secretion.
To prevent them, wake up in the morning and get some sunshine, exercise, or drink a warm drink to warm yourself up and start the day off active.
