Running is one of the simplest aerobic exercises, and it is precisely because of this that it is loved by the public. But some runners told Lao Wang that as long as they ran, they would catch a cold. At first, many runners mistakenly thought that they didn't pay attention to keeping warm after running, and finally they caught a cold even to keep warm, which was inexplicable! So some people began to doubt whether their bodies were not suitable for running. Lao Wang checked some information, and the real reason may be related to running intensity and diet. For example, it is easy to catch a cold if you ask yourself to run at high intensity every week (about 10 km or more every day). Because too much running exercise makes the body weak, that is, immunity and anti-inflammatory ability begin to decline sharply, and it is easy to be infected by external bacteria and viruses. Therefore, since running is regarded as a kind of physical exercise, don't give yourself too much pressure. It's really unnecessary. Running depends on perseverance, not short-term running. It is difficult for most people to give a clear definition of a cold. Usually, our understanding of a cold is likely to be a series of symptoms such as headache, sore throat, sneezing, runny nose and fever after a cold. Strictly speaking, there is no such thing as a cold.

Usually, the narrow sense of cold is commonly known as upper respiratory tract infection, and 70%~80% is caused by viruses (including rhinovirus, coronavirus, adenovirus, influenza and parainfluenza virus, etc. ).), and 20%~30% of infections are caused by bacteria, mostly self-limiting (self-healing). Various reasons that lead to the decline of the local defense function of the whole body or respiratory tract, such as cold and excessive fatigue. , it will weaken the immune function, and the virus or bacteria invading from the upper respiratory tract or from the outside will multiply rapidly, thus inducing the disease. In daily life, we usually think that colds are the main cause of colds, which is based on certain evidence. Cold makes the local capillaries of respiratory tract contract, and the immune response on mucosa is weakened. In addition, too cold will stimulate the thermoregulatory center, nervous system and immune system disorder, immunity is temporarily low, and viruses may take advantage of it. The relationship between cold stimulation and cold is also controversial. The National Institute of Allergy and Infectious Diseases said, "Contrary to common sense, a cold or a cold will not cause a cold."

The National Institutes of Health said: "There is no experimental evidence that exposure to cold increases the chance of catching a cold." People who run regularly consume twice as much carbohydrates as ordinary people. If the intake is insufficient, the body's immunity and anti-inflammatory ability will be reduced, and you will face the risk of "easy to catch a cold". 2. Eating soybean milk, eggs, fish or meat every time protein runs is a good source for enhancing immunity and anti-inflammation. Running is easy to catch a cold? Besides ignoring warmth, there are two main reasons you don't know. 3. Proper intake of healthy oil can effectively enhance the body's own immunity, especially for men, it can also enhance androgen and enhance sexual function.

Other nutrients such as zinc, iron, vitamins A, D, E, B6, B 12, plant polyphenols, quercetin, theanine in green tea, lactic acid probiotics, etc. It also helps to prevent colds. Although moderate-intensity exercise can improve immunity and reduce infection rate, high-intensity long-term exercise can inhibit immune function. Therefore, marathon runners and amateurs may be more likely to catch a cold. A survey found that among the 140 people who participated in the 56km Urtola Marathon, 33.3% caught a cold within two weeks after the race.
