Exercise may increase the effectiveness of your Covid-19 vaccine, a new study found: Here's how...

I am 60 years old, I am always in shape because my job requires me to be on my feet. I walk about 20,000 steps a day. I pick up heavy objects sometimes as heavy as 80 lb and I walk it or I put it on a dolly and drag it or walk it as far as 50 m. I wonder if doing all this and working 9:00 to 11 hours a day and getting out of a vehicle about 130 times helps me maintain physical fitness. Before I retired, I could prep for the Army fitness test or the Army Combat fitness test two weeks before the test and I could pass the acft or nearly Max the army physical fitness test just from my daily work at my delivery job. I wonder if that is why I was able to survive the covid-19 illness back when I got it last March of 2022 and I never received any vaccine. They say that those who have been afflicted have better immunity than those who got the vaccination or the boosters. Case in point both the president and first lady and the prime minister of Canada and and the first lady were all vaccinated and received their booster shots and they still got sick multiple times. I meet customers all the time to get signatures so I get exposed to others as well who may have the coronavirus and not know it. Did they ever consider that hypothesis? I also have no comorbidity issues. I don't drink, smoke, do drugs or have a compromised immune system. My job supposed to be under a lot of stress and that could lower my immunity but yet I only got sick once. Luckily, I got sick during my vacation so it did not affect my income.

I did not tell the military but I actually had asthma as a kid but yet I survived the CS gas chamber in basic training.

I am white and Latino. For some reason they consider Latino to be not white but they don't consider those whose forefathers on my belated Mother's side who left from the Iberian Peninsula as white leaders from Spain sent to the Americas living in Latin America like Honduras.

I am 5'11 180 lb and I can get my blood pressure to be under 120 over 80 just by relaxing.

..."Exercise may lower chances of severe outcomes from Covid in unvaccinated people, too
"We had another study which showed that in people who contracted Covid – and those were unvaccinated individuals – those who engaged in the recommended 150 minutes a week of exercise, had better outcomes," says Patricios.

"They were admitted to hospitals less, fewer of them were in the ICU and on respirators and fewer of them died."

Similar to his research, a study was conducted on over 48,000 participants with Covid, before vaccines were available, to determine if exercise was associated with a lower risk of severe outcomes from the disease.

Researchers found that those who walked or worked out consistently, prior to infection, were about half as likely to be hospitalized due to Covid.

"This just further adds to that evidence base that people who are more physically active are healthier," says Joy.

While it has been widely studied that exercise can lower risks of noncommunicable diseases like dementia and cancer, "physical activity is also a successful strategy to prevent communicable diseases like Covid-19," Joy notes.

When it comes to physical activity for better health outcomes, she says, "none is bad, some is good [and] more is better.""

They say the same thing with just about everything. Proper diet, exercise, stay hydrated, etc. There have been people on all sides the spectrum (fit and unfit, and vaccinated and unvaccinated) who have died as the result of COVID.
