A plain winter observation.
The best night's sleep is often between the second alarm clock that is pressed off and the third alarm clock that has to be raised.
When the third alarm goes off, you'll sit up wrapped in a quilt like this.

So deliriously walked out the door.
So yelling in an inner breakdown.
Aaaaaaaaaaaaaaaaaaaaaaa!!!aa It's hard to get up in the winter morning!!!
Who isn't!
Since you can't get up early, turn grief into work and use practical actions to touch the boss's heart. We wrapped up tightly in the quilt and looked up a whole bunch of information in a daze.
Finally, we got a major discovery that might be right: it turns out that winter should be lazy!
Sleeping in winter is a matter of course
Seriously, winter can't get up, I really don't blame you.
This is first of all to blame for the cold weather.
Studies from multiple authoritative institutions have found that we sleep longer in the winter and less in the summer. The researchers speculate that this may be related to energy consumption.
People sleep significantly more in winter than in summer
People in the north sleep significantly longer than in the central and southern regions

With such low temperatures in winter, heat and energy are expended faster. Animals can hibernate, but we can't, and even on cold days we have to get up and work.
In this sense, lying in bed in the morning is actually a love for work. This is preparing for a busy day, both psychologically and physically.

In addition to low temperatures, light is also an important driver that we can't get up.
You may all have an observation: the winter dawns later, and the daylight is not as full as in the summer.
This change in light can affect the secretion of melatonin. That's right, the melatonin that many people use to help them sleep. This is actually a hormone synthesized by the pineal gland of the brain. Current studies have found that melatonin secretion is circadian, low during the day, begins to rise gradually after nightfall, peaks at 23 to 3 a.m., and then drops sharply before dawn.
When the outside light is bright, the secretion of melatonin is suppressed; when the outside light is dim, the secretion of melatonin is stimulated, helping us to better enter and maintain a good sleep.
So it was getting late that day... The secretory inhibition of melatonin can also be delayed. Hinting at you all the time: "Before you wake up, work is temporary, and the bed is your eternal home."
This may also be why many countries adopt winter time. The clock is set back by one hour as a whole, so that everyone can work at dawn and improve efficiency.
Of course, there's another possible reason why winter can't get up – you're anxious.
Year-end summary, final exam, performance talk, Spring Festival can not go home, seven aunts and eight aunts began to introduce objects... These complex things are piled together, often bringing about an increase in anxiety levels in large groups, affecting the quality of sleep.
In 2016, a study by the Vrije Universiteit Brussel in Belgium surveyed anxiety levels and sleep status in 1,083 adults. Studies have found that when people are overly anxious, falling asleep becomes more difficult and the quality of sleep deteriorates.
Well, this is even more difficult to get up...
Therefore, winter is the season of sleep, even animals have to hibernate, you don't have to struggle anymore!
Sleeping late in the winter is really exceptional
After delving further into the winter sleep, we have another big discovery!
Sleeping late in the winter is not only a natural thing, but also has some unexpected benefits!
The first benefit has to do with ourselves.
Getting up a little slower in the morning in winter and sleeping a little more may have a certain protective effect on cardiovascular disease.
When we sleep, the heartbeat rate will slow down, the blood vessels will be dilated, and the blood flow will slow down; and after waking up, the human heart will beat faster, the blood vessels will contract, and the winter morning temperature is low, the contractions may be more obvious, and the blood vessels will be under particularly large pressure. If you have coronary heart disease, the degree of coronary artery stenosis is aggravated, and it may even cause rupture of plaques in the blood vessels, producing acute thrombosis and inducing myocardial infarction.
A study published in the American Journal of Cardiology, which synthesized more than 30 surveys involving 66,635 patients, found that acute myocardial infarction, sudden cardiac death, asymptomatic ischemia and stroke were all in the morning. The probability of an acute myocardial infarction in the morning is about 40% higher than the rest of the day! Scared me tightly wrapped in a small quilt, it seems that the rumors are not false, getting up too early, not sleeping enough may really be inextricably linked to sudden death...
The second benefit has to do with our boss.
Employees sleep better, the company's operating costs can be reduced!
In 2017, researchers joined forces with Multiple Universities such as Hopkins University in the United States and University College London in the United Kingdom to investigate the economic cost of sleep deprivation in five different countries.
The results found that employees who slept less than 6 hours a day lost productivity due to absenteeism or attendance on average 2.4 percentage points higher than those who slept between 7 and 9 hours a day. Based on 250 working days a year, an average sleep-deprived person loses about 6 working days per year.

To put it bluntly, if employees sleep a little more, they can be more productive and make the business progress more efficiently.
After all, as the saying goes: "Sharpen the knife and don't cut the wood, wake up and work again!"
What's more, getting enough sleep can help us stay in a good mood and start the day in a better state!
Don't underestimate this, a good night's sleep can help our body repair DNA and clean up the brain "garbage". Sleeping more is equivalent to winning more precious opportunities for the body to repair itself.
The cold air, the whistling wind, being woken up by the alarm clock, thinking of the KPIs that will be faced at the end of the year, irritability, helplessness, and a sense of loss of control are mixed.
But if you can turn around, wrap yourself tightly in a warm little quilt, rub it, and sleep for a while, the world will be a little better. As the writer Shu Guozhi said, "How happy are people who lie in bed!"
Well, I know you're going to punch in, go to work, go to school, there's really no way!
It is better to synchronize such important information to the big (lao) family (ban) to see.
I have written the copy for you: "A joint study by Universities such as Hopkins University in the United States and University College London in the United Kingdom found that postponing the work time in winter can save enterprises huge expenses!" 」

The staff is happy, the boss is assured, let us sleep beautifully! (One more thing: if there are bad consequences, don't look for us!) ）
Slipped away...
