The onslaught of coughs, sore throats and sniffles may seem inevitable, but does constant exposure to infections such as colds or flu make us stronger?
Our immune systems are said to have memory, meaning that if an individual has previously been exposed to an infectious bug, such as a virus, specialized immune cells that remember what it looks like will continue to circulate in the blood and body fluids, ready to initiate a rapid immune response should they encounter In this case, there is no need for a serious infection with a virus or bacterium to cause a memory of it.
Our immune system is specific to the pathogen we have encountered before. The chair of the International Scientific Forum on Home Hygiene said that building immunity to lots of infections is self-defeating.
It's not a good idea to catch a cold just a few days later. The chair of the British Society for Immunology's Covid Taskforce said that there are lots and lots of different agents for the common cold.
What I wouldn’t advise is deliberately trying to get infected, because every infection has a risk
Exposure to disease-causing pathogens isn't necessarily good for us either There was a spike in cases of respiratory syncytial virus after Covid restrictions were lifted. Prof Murcia said that after people started mixing again they saw a lot of children with the virus.
Exposure, little and often, may refresh the immune system's memories of commonly circulating bugs, as well as updating them with information about new variant.
It's not necessary to ingest large amounts of them to make a difference.
Murcia said exposure and disease are not the same thing. Sometimes we mount a response without even knowing that we have been exposed to a pathogen. I wouldn't recommend trying to get infections because they have a risk.
Everyone's cold will be different. It depends on how old you are and how much exposure you had to the pathogen. It takes a lot out of older people who get colds, and they realize that. Younger people may be able to ignore it, but older people should not.
People are at risk of other illnesses, including Covid, if they breathe in common cold-causing rhinoviruses or pick them up off the ground.
There is mounting evidence that the immune system may be negatively impacted for weeks or months after the infection has subsided. The balance of circulating immune cells in people with long Covid has been found to be altered by Akiko Iwasaki's research.

They are showing a lot of changes that don't strengthen the immune system Rather, Covid-19 appears to be skewing the immune system in a way that makes it hard for people to respond to other infections.
According to an article in Nature Communications, there is evidence that exposure to sars-coV-2 may reduce the diversity ofbacteria in our guts. The results show how the gut and immune system are connected. According to the study, infections in one can cause disruptions in the other.
This isn't saying that we need to return to wearing masks. It's a good idea to avoid crowded indoor spaces if you want to avoid becoming sick. Regular hand washing, coughing, and sneezing into the elbow is also something that is done.
As autumn turns to winter, there are lots of bugs looking for a warm, moist host in order to reproduce. Is that host for you?
