Smell some coffee, refresh yourself

With tiredness, many people like to have a cup of coffee to refresh themselves. According to the Daily Mail of Britain, a new study by Japanese scientists has found that the aroma of coffee can also refresh the mind and relieve fatigue. The study is published in the latest issue of New Scientist.

Scientists at the University of Tsukuba in Japan first conducted experiments on mice. They kept 16 laboratory rats in a cage filled with water to keep them awake for 24 hours. Then, half of the mice smelled the aroma of fried coffee beans, while the other half did not smell any coffee. As a result, the former group survived significantly longer. After studying the structure of the brain, scientists found that the aroma of coffee can promote the activity of key nerves and reduce anxiety.

The researchers surveyed thousands of coffee lovers and found that the aroma of roasted coffee beans can relieve tension and calm down. The aroma of brewed coffee can also have the same effect. Scientists say studies have shown that sometimes a strong smell of coffee is enough to erase the negative effects of poor sleep on the brain. "when people burn the midnight oil, smelling the aroma of coffee can relieve tiredness, relieve stress and avoid insomnia." Professor Sukeo Gong, who is in charge of the study, said.

The researchers point out that extracting certain chemicals from coffee and spraying them into the air will one day become an important way for tired people to regain their energy. At present, scientists are studying the effects of other food flavors in detail. ▲
