The higher the doctor's level, the more he likes to drink coffee.

Perhaps in the eyes of many people, doctors belong to a kind of "infinite resources". Once needed, they can directly copy 180 copies by turning on the copier. They don't have to eat, drink, fall in love, rest or accompany their families. They work all year round, never get tired and never make mistakes.

There is a question in Zhihu: How horrible it is for doctors to work overtime. One of the answers wrote: "I think the most unbearable thing is that the surgery can't continue to work after work, and then work overtime for the next day's elective surgery. It's the feeling of adding 20 kilometers to the finish of the marathon. It's a bit complicated, don't be too sour at night. "

In view of the fact that doctors are often overworked and exhausted, coffee seems to be a "just need" in the medical field in the 2 1 century. The main reason for doctors to drink coffee is to relieve the fatigue of long-term work, followed by sticking to their posts at night, and some doctors are trying to stay awake.

Besides refreshing the brain, drinking coffee can also improve the cognitive ability of doctors. A study published in Annalsofsurgery pointed out that among surgeons, after drinking coffee, they will have a faster reaction to the operation and a shorter time to complete the operation.

Different doctors have different preferences for coffee. 20 15 Swiss scientists discussed the interesting question of "doctors like to drink coffee", and related articles were published in BMJ.

This survey, known as the most "wonderful work" in history, found that there were significant differences in coffee purchases by different doctors. Surgeons drink more than physicians, while anesthesiologists drink the least. On average, plastic surgeons drink the most coffee a year, followed by radiologists and general surgeons.

This may be because Swiss plastic surgeons give full play to their good habit of "working hard, having fun and drinking", so they often go to the cafeteria to buy coffee; Moreover, Swiss plastic surgeons have more free time and need some good ways to kill time.

Interestingly, for the "liking degree", different kinds of coffee also show gender differences: male doctors prefer espresso and female doctors prefer cappuccino. The author thinks that the difference between male and female doctors' attitudes towards coffee is closely related to marketing. "Coffee advertisements generally use gender roles. Men enjoy strong coffee, and women are drinking cappuccino and chatting with friends on the sofa. "

Perhaps it is not entirely the department and gender that affect their preference for coffee. The author was surprised to find that even doctors of different ranks have different degrees of preference for coffee. The older a doctor is, the more he likes to drink coffee.

When senior doctors are young, drinking coffee is probably a panacea for anti-aging and anti-fatigue. Because only in this way can we keep up with the pace of young people and not be swept away by the trend of the times. At the same time, a senior doctor also means having a larger social circle: the greater demand for coffee may also be a social expression of "please drink coffee".

In China, doctors also like coffee very much. Hospitals began to "cross-border integration" with cafes.

The "Twin City Cafe" in the Fourth Hospital of Zhejiang University is an outstanding representative. A few years ago, the westernmost part of the fourth floor of the outpatient department of the Fourth Hospital of Zhejiang University was an inaccessible terrace with an area of about 300 square meters. In order to provide a rest space for hard-working medical staff, former dean Chen Yagang took the lead in transforming the terrace into a cafe.

Here, doctors and nurses can exchange joys and sorrows at work, and young doctors can also put down red tape and chat with their predecessors. Being wronged, this is also an excellent place to vent. Because foreign guests are not accepted, Shuangcheng Cafe is also a relatively private "internal place", where patients who are not suitable for public discussion can also have free professional discussions.

The private hobby of doctors drinking coffee seems to have become a well-known and even officially supported "large-scale collective activity".

So, besides coffee, do doctors have any refreshing artifacts?

Tea has been popular in China for thousands of years. No matter what occupation, most people in China love tea. From national leaders, emperors and princes to ordinary people, many people like to drink a pot.

So, how will Dr. China choose between tea and coffee in the traditional beverage industry?

In fact, including doctors, people's preference for tea or coffee has long been a hot topic among psychologists and sociologists. It is rumored that tea drinkers are more traditional and pursue a quiet and indifferent life, while coffee drinkers are more innovative and adapt to a fast-paced life; Tea drinkers like to get up early, while coffee drinkers are used to staying up late. Tea drinkers have lower injury avoidance, higher self-orientation and persistence, while coffee drinkers have higher introversion and neuroticism, and higher self-orientation and reward dependence.

Scientists have also studied this. A study published in ScientificReports pointed out that people's perception of bitter substances is related to having a certain set of genes, which will affect their preference for coffee, tea or alcohol.

Using samples from more than 400,000 participants in the British biological sample bank, the researchers analyzed the genetic variation related to the perception of three bitter substances, propylthiouracil, quinine and caffeine, and evaluated the influence of bitterness perception on the intake of coffee, tea and alcohol.

The results show that people with more caffeine bitter gene receptors tend to drink a lot of coffee compared with ordinary people. Every time a caffeine bitter gene receptor is added, the proportion of people who like coffee will increase by 20%. The preference for caffeine is also related to the feeling of the tongue, because it is more sensitive to the rich taste of coffee, so the consumption will also increase. People who are sensitive to the taste of caffeine drink less tea.

Most people who like tea are quinine/propylthiouracil bitter gene receptors. Compared with ordinary people, the proportion of drinking more than one cup of tea every day will increase by 4%~9% for each additional quinine/propylthiouracil bitter gene receptor.

These findings show that our perception of bitterness is determined by genes, which will determine our preference for coffee, tea and wine. So drinking tea or coffee has nothing to do with occupation or even personality preference.

For doctors, it may be more about the status quo. Compared with foreign medical institutions, domestic doctors have greater work pressure and heavier tasks. High-tempo house calls and intensive shift work make young doctors and nurses choose to spend the least time making the most "instant" coffee.

For senior doctors, under the influence of traditional ideology and culture, the cup of Pu 'er in hand may be the most charming taste in the clinic at night.

So, since you are still writing a medical record, which do you like best, coffee or tea?
