Around us, there is always a Superman with good physical fitness. All the people in the office are blowing their noses, coughing and sneezing, but he is alone. Ask him know-how, the other side ha ha a smile: "no way, is born so healthy!" In fact, they are deceiving. Health is not innate. As long as you master the following tips, you can strengthen your immunity and stay away from diseases.
1. Sleep for 8 hours
Dr. Hamburg of the UK thought 50 years ago that the most helpful thing for a cold is sleep. Modern medicine experts say sleep is a good medicine for people with cold. When people sleep less, overwork, cold stimulation, the resistance will be reduced, induced cold and other diseases. If sleep is increased, the body's immunity will be strengthened. Research shows that when the virus strikes, people who sleep only 5-6 hours a night are 30% more likely to catch a cold, while people who sleep more than 7 hours a night are 17% less likely to have a cold.
2. Supplement vitamin C
In the 1970s, Linus Pauling, a Nobel Prize winner and chemist, once wrote a book called "vitamin C and the general cold", which made the idea that vitamin C can prevent colds deeply rooted in people's minds. He believes that if the lack of vitamin C, there may be bleeding gums, decreased resistance and so on. Vitamin C can promote the synthesis of immune protein, improve the activity of functional enzyme, increase the number of lymphocytes and improve the phagocytic activity of neutrophils. So more people suggest that patients should take large doses of vitamin C as soon as possible in the cold season or after cold symptoms.
However, this concept has been controversial in the industry. Scientists in Australia and Finland conducted an academic retrospective study and found that vitamin C did not prevent colds for the average person. But when adults take vitamin C, they recover faster after catching a cold. Experts believe that large doses of vitamin C can enhance the phagocytosis of white blood cells in the body and the ability of antiviral, shorten the course of cold. However, only a large dose of vitamin C can enhance the resistance.
According to a study by the University of Mellon, those who are happy, enthusiastic and calm are less likely to suffer from infectious diseases. They surveyed 193 healthy people and found that people who were optimistic had fewer cold symptoms and stronger resistance to upper respiratory diseases. Professor Hilton Cohen, who led the study, said: "people who are optimistic are less likely to have a cold than people who are depressed. The more positive you are, the less likely you are to catch a cold. " So the happier you are, the more relaxed you are, the less likely you are to catch a cold.
4. Know how to decompress yourself
If you live under pressure for a long time, your body will protest in different forms. In fact, a cold is a symptom of physical discomfort caused by stress. A previous Spanish study suggested that psychological stress was a risk factor for the occurrence of colds. Researchers surveyed 1149 college staff and found that psychological stress could increase the incidence rate of 1.9-3.7 by a factor of two.
5. Be hygienic and wash hands frequently
Cold and flu virus are easy to infect. As long as they touch the doorknob and table, they may be brought to you, because the virus can survive for 2 to 8 hours. And a US study found that 40% of people don't wash their hands after coughing or blowing their nose. Using the right hand washing method can keep one billion people away from cold and prevent other infectious diseases. So don't underestimate hand washing!
There are six steps for a correct hand washing method: the first step is to rub the palms with each other and fingers together; the second step is to rub and exchange the palms with each other along the finger joints; the third step is to rub and exchange the palms with each other with hands crossed along the finger joints; the fourth step is to rub and exchange the thumbs of one hand and the other hand; the fifth step is to bend the joints of each finger and rotate and rub them in the palm of the other hand Wipe and exchange; step six, scrub your wrists and exchange.
6. Multi Sport
Research shows that regular exercise can improve blood circulation and enhance resistance. Even if bacteria invade the body, the body will wipe them out. In addition, the American Sports Medicine Association points out that exercise can help relieve cold symptoms. Moderate exercise can reduce the number of cold symptoms by half.
7. Love onion, ginger and garlic
These heavy flavored condiments can not only make the dishes taste better, but also help people avoid cold unconsciously. Research found that garlic is rich in antioxidants, which can be called "antibiotics" in food, and can quickly kill the bacteria in the early stage of the cold. Ginger contains gingerol, which has powerful medicinal value, can help digestion, reduce nausea, fight against influenza and common cold.
8. Drink yogurt
Researchers at the University of California found that people who drank a glass of yogurt (natural or sterilized) a day had a 25 percent lower chance of catching a cold than those who never drank it. Before the flu season, get into the habit of drinking yogurt every day to strengthen your immune system.
In addition, people with frequent colds can try to work at home. Because in public places with many people, such as bus stations, subways and shopping malls, there are many cold viruses. These viruses are spread by people sneezing, talking, laughing, singing and so on. If you don't want to get sick, don't go around and have fun when you have nothing to do at ordinary times. Try to reduce the time you spend in public places and avoid "coming to your door" for illness.
