The outbreak of the new coronavirus to date, many places have the corresponding statistics, in addition to the number of infected people, there is a point also worth noting. According to the available data, the people who are infected with the new coronavirus are mostly those who have poor resistance, in addition to the elderly, it is necessary to count the obese and other people with poor health. And according to previous experience, we can also find that obese people are often more likely to suffer from the flu, this is because long-term obesity is reducing our immunity, so that our ability to resist the virus slowly become weaker. Most fat people have several common characteristics: poor basal metabolism and metabolic disorders, both of which will make their body skills in all areas are affected, and the physique will slowly deteriorate as a result. At the same time, obesity itself is a kind of inflammation, that is to say, the obese body is actually fighting with excessive fat every moment, which leads to the body’s resistance to lower than when the weight is normal, so that the germs have the opportunity to take advantage of. On the other hand, obesity will also cause a lot of accompanying diseases, most long-term obese people are suffering from fatty liver, high blood fat and other diseases, some also have diabetes, high blood pressure, the existence of these diseases will directly reduce the patient’s immunity, in addition to making them more likely to be infected with germs, the threat to life after infection is also greater than the healthy people. In addition, chronic obesity can also weaken heart and lung function, which makes pneumonia caused by colds or new coronaviruses even more dangerous. Therefore, during the epidemic, people who are chronically obese should take greater care to protect themselves and take precautions. When the epidemic is over, they should also actively lose weight and slowly improve their resistance in order to strengthen their ability to face various viruses.
