Oh god utter bollocks from this absolute weapon.
Your health has nothing to do with catching a virus, it’s chance and luck.
Your immuno response to it is another matter.
When the cells under attack from the virus send out a stress response, they release cytokines to let the body’s immune system know there’s an invader (aka virus) present.
The bod’s immune response, is what makes us “ill”. The feeling of being crap, fevers, chills etc aren’t being caused by a virus - it’s the body’s response to the virus.
Having a healthy heart for example, will better equip your body to deal with the extra stress of this immune response. Having the adequate hydration and minerals will equip the body to withstand the assault it’s being put under by our immune system sometimes the imuno response can be a little overzealous, which varies by individual and those specific circumstances, and an cause more harm than good.
It’s why the Spanish flu at the turn of the century was so deadly to young, healthy people. Their immune responses were too aggressive. In the words of Cambridge Uni press;
“A well-known feature of the great H1N1 influenza pandemic of a century ago is that the highest mortality rate was amongst young adults. The general explanation has been that they died from an over-reaction of their active immune systems.”
in summary… immune systems are complex systems made up of innate and adaptive responses. The innate response triggers an immediate, nonspecific, general action and is activated by typical signs of infection. The adaptive response is able to develop a highly specific, extremely accurate action, which is stored in the immune memory (aka antibodies).
it’s not as simple as exercise + decent food = ability to overcome diseases. There’s more at play here, and it’s irresponsible to simplify it in the way bradders has. Does this guy even have a GCSE in biology? Why is he wading in on something he doesn’t understand?
