@Dr_Shiv_kumar_ The host-pathogen interaction is where the nuance lies. It’s not that the cold is the virus, but it definitely weakens the border patrol (neutrophils/lymphocytes) via vasoconstriction. Perfect way to explain how the environment sets the stage for the pathogen
Cold air, AC, or rain don’t cause a cold
But cold exposure leads to decreased nasal immunity + dry mucosa + indoor crowding + Vasoconstriction of nasal blood vessels( decreased delivery of neutrophils & lymphocytes ) & easier viral entry.
Same goes to AC/Cooler/drenching in the rain virus/bacteria’s survive better in cooler environments. So it’s the virus taking advantage.
The answer lies in respiratory physiology. While viruses and bacteria are the primary causes of infection, physical factors create a permissive environment for them to thrive.
First, exposure to cold triggers local vasoconstriction. When the blood vessels in your throat narrow, it reduces the immediate delivery of white blood cells specifically neutrophils and lymphocytes to the area. This temporary drop in local immunity allows any existing viral or bacterial load to take hold more easily.
Second, constant airflow from a fan or AC leads to mucosal drying. Your throat is lined with a protective mucus layer and tiny hairs called cilia that move pathogens out of your system. When this lining dries out, the escalator stalls. This cracked barrier makes it much easier for germs to invade the underlying tissue.
In short: The virus or bacteria is the cause, but the cold and dry air are the physical catalysts that disable your body’s first line of defense.
How to avoid it:
• Nasal Breathing: Use your nose; it’s your natural humidifier and filter.
• Indirect Airflow: Position fans/AC so they don't hit your face directly.
• Hydration: Keep fluids up to ensure your mucus layer stays functional.

“The United States has murdered 38 million people across 152 countries between 1971 to 2021” 🤯
The same US claims to liberate Iran 🤣
We must make this clip live in infamy. The criminality of Israel, and the abject shame of US, Britain and the other genocide apologists at UNSC. The Palestinian representative holds a mirror to them, so that they can see their ugliness, this will ring through the ages. #NeverForget Gaza…
@MikeSonko My backpack that would contain my life dependant meds, my kids epipens and inhalers with all their medical equipment and documents, along with their id and important details medical staff would need in case of emergency?
No. I'll be taking mine.
@InfluencialLaw @muftimenk@simply_nikah_ Because unfortunately you get some who are mistreated. And it is cruel to tell them to stay in the marriage. This can give those a second chance so to speak, isn't that a good thing? Other divorcees may be looking for other divorcees as well.
The Q: “Isn’t the U.K. recognising Palestine statehood giving Hamas a win?” lacks any context at all.
146 out of 193 U.N. member states officially recognised the State of Palestine long before the U.K. did today.
So surely the Q should be: Why has it taken the U.K. so long?
@Cool_Ustaz 8 years too late for me! This would have been much needed back then when I didn't know anything! Had no idea nikah had such intricate process. Husband made all the demands, no walimah no ceremony no legal document signing just a private nikah with family :(
