Relevant experts said that staying up late is actually violating the biological rhythm of human beings, if you don't sleep at night, the body will be out of excitement, sympathetic nerve stimulation of the body to release a large number of catecholamines, which will cause electrocardiogram instability, but also easy to cause fatal arrhythmia. That's why so many sudden deaths occur between the wee hours of the morning and the morning.
Everyone generally thinks that staying up late is just an irregular schedule and doesn't have much effect. However, in the face of the facts, staying up late and staying up all night will increase the risk of sudden death.
For medical staff, no matter what department, especially in the prime of youth, stay up late to prepare for exams and stay up on duty...... Staying up late is simply unavoidable and commonplace. According to the new White Paper on the Practice of Chinese Physicians, almost all doctors have worked more than 24 hours in a row, half have worked more than 36 hours in a row, and about 20% of doctors have even worked 48 hours or more. In addition, night shifts are also the norm for clinical medical staff.
In many laboratory departments, the night shift is 15 hours from the evening before to 8 or 9 a.m. the next day.
And in this long night, because there is only one person on the night shift, there may not even be time for water to drink, and there may not be time for toilets. As for whether you can take a nap, it's basically not even a matter of even thinking about it.
Endless specimens are sent from various clinical departments or outpatient emergency departments. After all, it is a night shift, and it must be an emergency inspection, and it will not be able to achieve results for too long, and it will either be complained about or deducted money. In addition, what gastrointestinal bleeding, ectopic pregnancy, acute pancreatitis, food poisoning, these emergency tests also need to be the first time to get results.
So there was only one person in the open department who was busy, and the midnight bell kept ringing outside the door, and the phone rang continuously. The instrument whimpered there. At the same time, it is necessary to deal with the sudden failure of the instrument, and learn to analyze the results of incurable diseases by yourself.
If you see too many night shifts like this, you may be numb, but if you meet a few strange patients and have to communicate patiently for a long time, it will be even more sour.
According to the new White Paper on the Practice of Chinese Physicians, almost all doctors have worked more than 24 hours in a row, half have worked more than 36 hours in a row, and about 20% of doctors have even worked 48 hours or more. In addition, night shifts are also the norm for clinical medical staff.
It is difficult not to have a negative impact on the body caused by the irregular work and rest caused by the night shift:
1. Vision loss
Long-term night shifts mean overloading your eyes, which not only causes dark circles, but also causes problems such as dry eyes, pain, and even dry eyes. In addition, long-term eye muscle fatigue can easily cause vision loss, causing people to have vision problems such as blurred vision and distorted vision.
2. Decreased reflexes
Long-term night shifts can also cause damage to the brain, making reflexes decrease. A British study has shown that 24 hours of not sleeping is as harmful to the human body as drunkenness, with a blood alcohol concentration of 0.1%, which makes people unresponsive, slurred, and uncontrollable.
3. Affect gastrointestinal function
Long-term night shifts, changes in eating habits, and three meals a day that should be carried out at normal times are delayed to abnormal times, which can easily cause adverse effects on the stomach and intestines.
4. Hormonal level disorders
Long-term night shifts and circadian rhythm disorders will interfere with the normal hormone levels in the body, leading to endocrine disorders, reducing the body's immunity, and giving diseases a chance to take advantage of.
5. Induce high blood pressure
Studies have shown that people who sleep less than 6 hours a night on average are more than twice as likely to develop high blood pressure as those who get enough sleep.

An experimental study of fruit flies published in the authoritative journal "Cell" also confirmed that all fruit flies that stayed up late every day died. In short, various experiments have proved that staying up late for a long time without sleeping will really die early.
