Reducing The Effects Of Common Viruses
Some years ago it occurred to me that staying near someone who coughs or sneezes in an indoor environment is an unwise thing to do because it seems the old adage about coughs and sneezes spreading diseases is true. However, it is accepted as scientific fact that it takes a number of viruses or bacteria to infect a person. Smaller doses, therefore, should not cause infection but would be expected to give some immunity to the infective agent.
With the above reasoning in mind I began to move away from people who are coughing and sneezing and have found that cold and flu symptoms seem to be milder than they used to be. In public places we are all constantly receiving small doses but it seems to be a longer period of proximity to an infected person which produces the heavy flu symptoms we all know.
The immune system multiplies its defences when exposed to something infective so it seems reasonable that keeping infectious doses small with this simple practise could help the immune system to cope with infections. If it doesn't completely prevent infection it at least seems to give the immune system a head start and to make infections of the common variety milder.
