What Cold and Flu Viruses Mean for the Body
Since viruses have no natural means of replicating themselves, they must rely on our body’s cells to produce copies of themselves. Once the infected cells has performed the function of permitting the virus to replicate, it dies. However, the viruses that cause the cold and flu will mainly affect your weakest cells – cells that have already deteriorated with excessive waste and toxins. Your body need these cells to continually be replaced anyway, by stronger, healthier cells.
In a manner of speaking, a cold or flu can act as a natural means for purging the body of old and damaged cells – that would take longer to expel from the body in the absence of a viral infection. As long as you keep your body well rested and stay hydrated and fed during a cold or flu, becoming vaccinated or consuming medications that suppress symptoms are both unnecessary. All of these unpleasant symptoms are actually a process where your body is working to eliminate excess waste.
However, it’s important to be aware that because colds and flus can benefit the body, it doesn’t mean that they are necessary for maintaining good health. If you partake in regular care of your immune system through adequate rest and healthy nutritional and lifestyle decisions, your cells may be strong enough to withstand infection by these viruses.
According to a report by US researchers in the British Journal of Sports Medicine, if you want to reduce the frequency and severity of cold symptoms, you should exercise at least five times a week and remain physically fit. Not only do fit people encounter colds less frequently, but when they do, their symptoms are significantly milder than others who are not physically fit.
Researchers from North Carolina followed upper respiratory tract infection frequency and symptom severity over the course of twelve weeks in late 2008 on 1,000 individuals aged 18 to 85. Information was then collected on the frequency of aerobic exercise. Each participant was also asked to rank their level of fitness on a 10 point scoring system.
The results indicated that those who were most physically fit and exercised at least five times a week had a 43% to 46% reduced frequency of colds compared to those who exercised only once a week at most. Additionally, the fittest participants had a 41% lower symptoms severity, while other regular exercisers had their symptoms lowered by 31%. The authors explain that exercise sessions trigger a temporary boost in immune system cells that circulate throughout the body. Though the immune system cells eventually return to normal levels following exercise, they begin to improve the body’s surveillance of pathogens; this leads to fewer and less severe infections.
