Chapter 646: Preparation for Eternal Night
It was still dark and the ground was grey.
The entire ice field was in full view, with no sign of life at all.
A pair of large gloved hands suddenly stretched out from the ground and swept the accumulated snow aside.
Bifang panted heavily and pushed the snow away with great effort. The strong wind all night had completely blocked the entrance to the trench, which was at least thirty centimeters thick.
Leaning against the exit, Bifang took a breath, grabbed the ice on both sides, propped up his whole body, and then began to reel in the rope.
After a night of freezing, the rope was frozen solid. What was frozen from a few drops of water last night was already several centimeters thick today.
The thickness of the ice is increasing.
After tying the rope and putting it in the backpack, Bifang turned on the live broadcast and said hello.
"Today is the second day of my Arctic survival. I feel pretty good. Although I'm a little hungry, there are only ninety-nine days left, right?"
[I called 666 directly]
[I have to give this a full score. Don’t ask why I don’t leave any points for encouragement. He deserves it.]
[Waking up in the middle of the night to watch live broadcast, mom will beat you up series]
[I’m so sleepy, and I haven’t had my holiday yet]
The time difference between Greenland and China is seven hours, so there are not many viewers here at this time.
Although Bifang’s live broadcast has already gone global, domestic audiences are still the main force.
[Is it dawn in the Arctic? ]
On the screen of the live broadcast room, the audience found that the sun had not risen yet, but it did not seem as dark as they had imagined, and the night mode of the drone was not turned on.
"Because snowflakes reflect white light. The complex structure of snow cannot absorb light. A beam of light entering a snowdrift is quickly scattered by billions of ice crystals and air pockets, and most of the light is reflected back from the snowdrift."
"So as long as there is a little light, the places where there are snowflakes will appear brighter, but it's only dimly bright."
Bifang pointed to the stars in the night sky and clearly indicated the source of the light.
For most people living in cities, it is difficult to imagine a night with starry skies. Even after the sun sets, the night is never completely dark.
When the moon is full, it is incredibly bright, as if it were illuminated by street lights.
The moon in the night sky is not round today, but there is still a lot of light. In addition, the strong wind blows up the snowflakes, forming fluttering snowflakes four or five meters below the ground, which makes the sky brighter.
Although it was bright, the snow all over the sky made it impossible to see the road clearly. Fortunately, the North Star could be vaguely seen, which helped Bifang find the right direction.
"There are more than ten hours every night now. We can't waste this time. We can get up within three hours before the sun rises."
"To survive in the Arctic, you must keep your biological clock in check every time you enter polar day or polar night. Otherwise, the reversed schedule will make you feel very exhausted and often have headaches."
"Sleeping too much or too little will cause headaches, leaving you with insufficient energy to cope with the next challenge. So if you have the conditions, you must set an alarm clock. If you don't have the conditions, you can only rely on your body's own biological clock, but relying on the biological clock is a very difficult thing."
"How many of you like to stay up late? How often?"
While Bifang was on his journey, he suddenly asked a question.
「Ah, this.」
【Be more confident, every day】
[Alas, actually I don’t study or work until midnight, but I’ve been doing this all day, and I always want to check my phone and relax for a few hours at night, and before I know it, it’s already very late]
[Plus one, my head hurts every morning when I wake up]
[I work until eleven or twelve, so how can I be willing to go to bed directly? My life needs entertainment, so of course I have to relax, and then I fall into a vicious cycle (covering my face)]
Eight hours for work, eight hours for play, and eight hours for sleep.
This is the product of a long struggle, but now the working hours are usually more than ten hours, and sometimes twelve hours.
Most people work for a better life, so they cannot lack time for entertainment, which naturally encroaches on their sleep time. Otherwise, life will be meaningless.
There are very few people who are financially independent, and life just keeps moving forward like that.
Sometimes, when people see Bifang running around the world in a carefree manner, they can't help but feel envious.
Although some of his behaviors may cause controversy, Bifang doesn't care. Compared with those who support him, those are just a minority.
"In fact, many people's biological clocks are not 24 hours a day, but there is a certain error. Usually the error is within two hours. For example, a cycle may be 26 hours, or even 22 hours, but most of them are slightly longer than 24 hours."
"This is a universal phenomenon. The biological clocks of most diurnal animals are slightly longer than 24 hours, and the biological clocks of most nocturnal animals are slightly shorter than 24 hours. Humans are diurnal animals, so they belong to the former. Of course, there are exceptions. This is not a theorem, but a summary rule."
"We don't know the reason for this yet. One possible hypothesis is that when humans were born, the Earth's rotation period might not be 24 hours. This is because the Earth's rotation speed has changed several times over the past few billion years."
After hearing this, the audience in front of the screen seemed to have a door opened, and felt a wake-up call.
[No wonder I stay up late every day, the later I stay up, the more damn it is! ]
[Stay one hour longer each time, and after 24 days, you will be perfectly back to normal.]
"Take light as an example. Most humans' biological clocks are slightly longer than 24 hours. So humans live most comfortably in a light-dark cycle slightly longer than 24 hours, because it is completely in line with their own circadian rhythm."
"And the Earth's 24-hour light-dark cycle is actually adaptable, and the difference is not that big. If the light-dark cycle is 50 hours, it is generally not possible to adapt."
"In other words, the human biological clock can be adjusted to adapt to the external environment, but this adjustment is limited."
"In other mammals, light can regulate the biological clock through the suprachiasmatic nucleus in the hypothalamus , but once there is no light, you can only rely on your usual habits."
"Once this cyclical biological habit is disrupted, the consequences include memory loss, lack of energy, headaches, and in severe cases, frequent diarrhea and vomiting."
“So, self-discipline is very important.”
Bifang continued to move forward. It was thanks to his own biological clock that he was able to wake up on time so that sleep would not disrupt his forward plans.
They kept moving forward until the sky turned pale, the wind and snow gradually died down, the snowflakes on the ground gradually died down, and under the sunlight, the continuous mountains and rocks in the distance finally appeared in everyone's sight.
“We’re finally here.”
Bifang breathed a sigh of relief. The ups and downs meant there were mountains.
Where there are mountains, there are rocks, soil, plants and animals.
Although it is said that a horse will die if it is run to the mountain, it is still much better than not being able to see the mountain at all.
