Recent research shows that prolonged tension will weaken the body’s ability to resist germs, making it easy to catch a cold, the formation of the so-called cold body. British scientists at the Salisbury Cold and Flu Research Institute isolated 394 voluntary test subjects from the outside world for nine days, and on the second day, they put a few drops of colorless, transparent liquid into the noses of the test subjects. They were examined every day in order to record coughing, wheezing and runny noses, and most of the infections could be known early by blood tests, which showed the same results as the psychological tests done on the subjects before the quarantine. This suggests that the higher the level of stress, the greater the likelihood that the cold virus will take effect, and the results of the study showed that 47% of those who took part in the trial became ill as a result of their heightened state of stress, while only 25% of those who were not stressed became ill. What kind of food can relieve emotional cold? 1, banana Banana contains alkaloids, which can lift the spirit and improve confidence. And bananas are one of the sources of tryptophan and vitamin B6 in food, they can all help the brain to make serotonin and reduce the production of depression. You can eat a banana in the afternoon for an extra meal or breakfast to help reach the amount of fruits in a day. 2, chocolate eating chocolate makes people happy, this is due to chocolate in the brain to release the complex amine. Complex amines are formed by tryptophan, the human body itself can not be manufactured, can only rely on food from the outside world. Chocolate itself tryptophan content is not high, but it contains a lot of sugar, can trigger the generation of insulin. Insulin ensures that the sugar goes into the cells and the tryptophan that remains goes into the brain to be synthesized into complex amines. When the complex amine stays in the brain nerve bonds will have a positive impact on a person’s mood and help drive away frustration. 3, milk People with calcium deficiency in the body, the nervous system is in a state of over-excitement. Calcium deficiency in children will cry incessantly, calcium deficiency in adults is easy to be angry, emotions are very difficult to control. Calcium deficiency will also exacerbate insomnia, and poor sleep is often worse temper, milk is the best source of calcium, a glass of fresh milk in the morning and a cup of yogurt in the afternoon, is also a source of happiness. 4, grapefruit Grapefruit rich in vitamin C can not only maintain the concentration of red blood cells, so that the body has more resistance, and vitamin C can also be anti-stress. Most importantly, in the manufacture of dopamine and adrenaline, vitamin C is one of the important ingredients. 5, deep-sea fish Studies have found that people who live by the sea all over the world are happier. This is not only because the sea is refreshing, but also because people who live by the sea often eat deep-sea fish. Harvard University researchers pointed out that the sea fish in the OMEGA-3 fatty acids and commonly used antidepressants such as lithium carbonate has a similar effect, can block the nerve conduction pathway, improve the secretion of serotonin. 6, whole wheat bread carbohydrates can increase serotonin secretion. Researchers at the Massachusetts Institute of Technology have said that there is a scientific basis for eating pasta, snacks and such foods as antidepressants.
