Understanding the Common Cold: Why Fighting Off Illness Leaves Us Feeling Poorly
By: WPS News Health Correspondent
Baybay City | August 7, 2026At the heart of the body’s reaction to a cold is the immune response. When a virus, such as a rhinovirus, enters our system, our immune system springs into action. White blood cells, including macrophages and lymphocytes, recognize these invaders and initiate a complex defense process. They release signaling molecules known as cytokines, which play a crucial role in communication between cells during the immune response.
The release of cytokines triggers inflammation, particularly in the respiratory tract. This inflammation results in symptoms like a sore throat, nasal congestion, and a persistent cough. Blood vessels become more permeable, allowing immune cells to reach the site of infection. While this response is vital for combating the virus, it often leads to the discomfort and malaise we associate with colds.
The release of cytokines triggers inflammation, particularly in the respiratory tract.
Additionally, the body demands more energy to mount a defense against the infection. This redirection of metabolic resources can leave individuals feeling weak and fatigued. Altered levels of neurotransmitters in the brain during this immune response can also contribute to feelings of lethargy and, at times, even mild depression.
The combination of mucus production, coughing, and general discomfort from inflammation results in symptoms like headaches and muscle aches. While these signs are indicative of the body’s work to eliminate the virus, they can make recovering from a cold a challenging experience.
In summary, the discomfort experienced during a cold is a direct result of the body’s immune response and the inflammatory processes it triggers. Understanding these mechanisms not only demystifies the experience but also highlights the importance of allowing our bodies the time and care they need to recover.

🔥 What Keeps Intestinal Inflammation in Check
A research team led by Dr. Mauro Corrado at the CECAD Cluster of Excellence for Aging Research and the Center for Molecular Medicine Cologne (CMMC) at the University of Cologne has now discovered that a lipid called #cardiolipin regulates our #immuneresponse in the gut and thus determines the severity of #inflammation.

On August 4, 2025, #Meat & #Livestock #Australia announced a $20 million research partnership with #TibaBiotech & the #NSW Government to pioneer a world-first #biodegradable #mRNA #vaccine for #footandmouthdisease (#FMD). While Australia remains FMD-free, this step was announced to safeguard against potential outbreaks that could cost the Australian economy up to $80 billion.
The vaccine, tested in Germany, uses mRNA technology to trigger an #immuneresponse in #cattle.

"Maybe you already know how your immune system works, but you’d like someone to sum it all up in a way that helps you articulate the details when your friends and relatives bash you for protecting yourself.
So, where did this idea come from—it’s good to get sick?
It has a history.
Let’s start with a basic question: Where exactly did this idea come from that you have to train your immune system?"

CW: Covid, vaccines, asking for advice
Since several people liked my post above #AskingForAdvice about the #Novavax versus #mRNA #covid19 #vaccines, I thought I'd share this article from Science magazine that I found on the subject: https://www.science.org/content/article/should-you-pick-novavax-s-covid-19-shot-over-mrna-options.
It sounds like overall more research is needed, like so many other things related to #covid. But I appreciate folks weighing in with their knowledge of the #vaccine options and #ImmuneResponse!
And ultimately, we're still in a #pandemic. #CovidIsNotOver, and the best thing we can all do to protect each other and ourselves is to #MaskUp and get the latest vaccine, whether it's Novavax, #Pfizer or #Moderna.
If other folks who are #CovidCautious or #ZeroCovid or know about #Immunology or #epidemiology want to weigh in, please do! I've boosted several responses from folks giving more info, some in favor of mRNA vaccines and some in favor Novavax.
Antivaxxers and covid deniers will still be blocked.

CW: Covid, vaccines, asking for advice
#CovidCautious folks, a question about the new #covid19 #vaccines came up in my local group and I was hoping folks here could weigh in. Is it better to get the #Novavax or #mRNA vaccine for #covid, especially in terms of preventing infection and transmission?
For a long time in #StillCoviding circles, I was hearing that Novavax seemed to give broader immunity to a wider range of variants. But more recently, I've heard that Novavax doesn't illicit as strong a T-cell response as the mRNA vaccines. This claim seems counter to what I'd heard previously, and I'm hoping those who know more than I do can weigh in.
Regardless, I realize that getting any #vaccine is better than not getting vaccinated. And I know that #CovidIsNotOver and will #WearAMask because that's the only reliable way we can prevent infection and transmission.
Antivaxxers and covid deniers/minimizers who respond will be blocked.
