I *curse the cold viri's*
Hard not to catch one when you're physically touching 40 plus people a week..
Wash Hands~!! 99% of all germs are vector carried.. so being our hands are their magic carpet ride to their next victim.. wash with good friction and forget those bacteria killer soaps.. they do more damage to the natural flora on your skin than any good..
Hydrate..
Hot liquids.. the steam as you cup a bowl of chicken soup to your face is good therapy.. smells better than vicks too
avoid milk producs when congested.. Milk contributes to making mucous thicker.. not a good thing when you can't breathe anyway.
Don't sniff if you can blow.. just blow your nose easy.. sniffing and hard blowing of your nose will force pressure and whatever is in your nose to your eustachian tubes.. not good.
Analgesic for aches and pains
So many thoughts and studies on Vit C. /zinc and Echinacea, if they seem to help.. go for it. .the power of the mind is amazing.
If you find something that works.. use it

As long as you're not sticking Vicks vapor rub up your nose

Under the nostrils, alongside the nose, temples and chest/throat.. all good..
*Still cursing cold viris'*
