Corona and Corona-like viruses: According to the news the most affected people from Covid-19 are those who have weaker immune-systems by age, smokers, chronic diseases, hypertension, heart problems, diabetus mellitus, and so on.
Prof Janet Lord, Director of the Institute of Inflammation and Ageing, at the University of Birmingham, and co-author of a research, said (Duggal et al., 2018): “The immune system declines by about 2-3% a year from our 20s, which is why older people are more susceptible to infections, conditions like rheumatoid arthritis and, potentially, cancer. “Because the cyclists have the immune system of a 20-year-old rather than a 70- or 80-year-old, it means they have added protection against all these issues.”
30 to 60 minutes of moderate to intense activity can help your immune system keep viruses at bay. Be sure you know what’s going on in your area and whether there are any restrictions or mandatory self-quarantines. And, if you’re sick or at-risk of spreading the virus, you shouldn’t go out—the bigger concern is spreading it to those who are at high risk, such as the elderly or immunocompromised[1].
Latest research by Mohammed and Alawna (2020) found that increasing the aerobic capacity could produce short-term safe improvements in the function of immune and respiratory systems, particularly those specific for COVID-infections. This could be mainly produced through three mechanisms. Firstly, it could improve immunity by increasing the level and function of immune cells and immunoglobulins, regulating CRP levels, and decreasing anxiety and depression. Secondly, it could improve respiratory system functions by acting as an antibiotic, antioxidant, and antimycotic, restoring normal lung tissue elasticity and strength. Lastly, it could act as a protective barrier to decrease COVID-19 risk factors, which helps to decrease the incidence and progression of COVID-19.
Japanese study finds 1 case of COVID-19 linked to running. Of the close to 700,000 people involved in 787 races since July, there has only been one reported case of coronavirus. According to a research report (JAAF, 2020) it was documented only one case of someone who was involved in one of the races contracting COVID-19 in the two weeks following the event they attended. The study surveyed 53 organizations including the JAAF and corporate and collegiate league governing bodies. As of Nov. 6, 47 of the groups had returned responses. A total of 571,401 athletes and 98,035 officials and staff took part in the 787 races covered by the survey.
To prevent cold and flu: Exercise boosts blood circulation making it easier for all the immune cells in the body to get around searching for any flu viruses and inactivate them. Also, it helps stimulate the lymphatic system that helps in eliminating waste and toxics.
The most effective methods to alleviate symptoms of colds and simple flu that researches has revealed are running and exercising; outdoors, or indoors in winter. Viruses cannot survive in a high temperature environment. Accordingly, the self-protecting metabolism automatically increases the temperature of the body to protect against the virus. In the recent medical literature it is stated that keeping the immune system strong will be preventive against flu and colds, as in many diseases. It has been also stated that exercising and jogging with mild sweating and taking the necessary precautions right after the cold and flu – not being sweaty, nutrition and medication if necessary – increases the possibility of getting rid of the disease more easily and quickly.
Running on a treadmill will certainly help you sweat, but it’s also a great calorie burner. Burning fats and calories helps maintain weight, which is essential to prevent cold and flu. Maintaining weight through a healthy lifestyle and exercising regularly helps prevent diseases like cold and flu as your body is fitter and healthier.
Exercise may boost your vaccine response
Official Vaccines page from the World Health Organization (WHO,n.d. ) states that vaccination is a simple, safe, and effective way of protecting people against harmful diseases, before they come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger.
Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.
During the COVID-19 pandemic, vaccination continues to be critically important. The pandemic has caused a decline in the number of children receiving routine immunizations, which could lead to an increase in illness and death from preventable diseases. WHO has urged countries to ensure that essential immunization and health services continue, despite the challenges posed by COVID-19
The researchers speculate that the athletes’ immune techniques had been strengthened and fine-tuned by the day by day bodily calls for and damages of coaching, permitting them to reply so successfully to the vaccine.
These research targeted on elite, aggressive athletes, which most of us usually are not. But Dr. Sester believes even more-casual leisure athletes are more likely to mount higher flu-vaccine responses than sedentary folks. Likewise, she and her colleagues count on excessive health ought to enhance immune responses to different vaccines, together with, probably, a Covid-19 shot (24NewsOrder, 2020).
