Good advice courtesy of my SIL:
“But in order to make sure that flu shot is effective, sleep specialist Matthew Walker, the bestselling author of “Why We Sleep,” told CNN’s Christiane Amanpour practicing “good sleep hygiene” is key. Insufficient sleep in the week before getting a flu shot can lead to the production of less than 50% of the normal antibody response — a reaction that would render the flu shot largely ineffective, Walker told Amanpour.

Oooo… Doctor-prescribed naps are the best naps!
I myself got 8 and a half hours sleep last night in preparation for next week’s (hopefully!) flu shot, and I sure did need this prompting to put slept the top of the priority list. Otherwise, what is the point of getting the flu shot? I have not had it in many years but will this year as it is going to be the Covid-19 winter and I am doing what I can to stave off all harm.
Then Daughter and I should be good. (Where are the emoticons when you need them?)
Doing my part!!
Huh, that’s good advice that I never heard before. I mean, yes I’d heard that sleep is important. But not that it impacted whether or not the flu vaccine was effective.
