Basic knowledge of boutique coffee caffeine helps to improve work efficiency

Some office workers like to have a cup of coffee and take a nap during working hours. This behavior seems to be lazy, but a new British study shows that drinking coffee can increase work motivation and efficiency.

The study was published by Cochran Library, an online medical electronic journal.

Reduce mistakes

Researchers at the London School of Tropical Medicine and Hygiene reviewed 13 independent studies and analyzed the link between caffeine and work errors.

These studies come from many countries around the world and study shift workers between the ages of 20 and 30. The researchers placed the volunteers in sleep laboratories that simulated the work environment and examined changes in memory, concentration, expression and reasoning, as well as the probability of making simple mistakes.

The Daily Telegraph quoted study leader Catherine Kerr as saying on the 12th: "the relevant research results show that caffeine can reduce work errors and improve people's cognitive performance."

The study found that drinking coffee scored higher on memory, concentration and reasoning tests and made fewer mistakes at work than methods such as taking a placebo and taking a nap.

Night shift Gospel

In industrialized countries, more than 15% of people need to work shifts or night shifts. This kind of work can easily lead to circadian rhythm disorders and biological clock disorders. For workers on long night shifts, having a cup of coffee between work has the same refreshing effect as a nap, the researchers said.

Caffeine can not only help these people reduce work mistakes, but also reduce the risk of traffic accidents and workplace accidents. For health care workers, drinking a moderate amount of coffee can also avoid medical accidents.

Because people of different ages have different circadian rhythms, and this study focuses on people in their 20s, whether caffeine can play a similar role in other populations remains to be further studied.

However, some people have expressed concern about this. Dr Peter Lin, a health specialist at the Canadian Broadcasting Corporation, said: "caffeine can relieve fatigue in a short period of time, but when the excitement fades away, people need more caffeine to achieve a refreshing effect." this can lead to sleep deprivation and change people's sleep habits. "

More benefits

A previous study showed that coffee is rich in chlorogenic acid and antioxidants, which protect the heart.

The researchers surveyed 374 people with heart disease and found that drinking one to two cups of coffee a day in patients with normal blood pressure helped prevent the condition from getting worse. But the protective effect of coffee has no effect on heart patients with high blood pressure, and if these people drink coffee, the result may be counterproductive.

In addition, caffeine can regulate the level of high-density lipoprotein cholesterol in the body, reduce the risk of developing Ⅱ diabetes, and play a slight anti-inflammatory effect.

Sources of caffeine include coffee, energy drinks, caffeine drugs and some foods that contain caffeine.
