On this note about old wives tales, I'm a woman. I've tried every medicine, multiple birth controls, diets, workout and stretch routines to help with period cramps and pain, and I get to try a method and then take what I think helps and adapt for a better test every month until I run out of eggs and here is the bottom line for me at 30 having optimised alot.
Yes drinking water, stretching/really being flexible and fit helps and at the very least needs to start a few days before...
Salmon avocado, iron like steak help with body recovery.
Epsom salt baths help with the cramps as a natural muscle relaxant so does ibuprofen...
It's actually ginger juice, that makes 90% of the pain go away. I bought a $99 breville juicer 8 years ago and lasted me as long. Just got a new one. Three days before I juice ginger with other things
Maybe apple, celery, lemon to help it go down.
Every time I go to the store to get it the cashier's comment they have never seen anyone buy so much ginger in their life, and if it's a woman I tell them my secret. I buy pounds of it and drink probably a quarter gallon the week before.
If you are a woman or have a loved one who suffers from severe period pain, this does amazing things.
That being said, have no idea about respiratory stuff.
An actual Coronavirus story:
I did hear the scientists looking into this said bodies are overreacting into respiratory failure, so maybe it is like many others illnesses potentially about suppressing an extreme over reactionaey autoimmune response.
Someone in my industry got it. 45yr old smoker had to be induced into a coma to avoid acute respiratory failure a couple of weeks ago, after being diagnosed with Coronavirus.
I think the public needs to stress more vulnerable smokers are regardless of age to Coronavirus. Smoking is much more common in China and Italy.
