Before you get a flu shot, get good sleep to increase its effectiveness, experts say
(CNN)We all know how much better we feel after a good night's sleep. It turns out that sleep may be vital to arm us in the fight against influenza and Covid-19. Medical professionals are recommending that people make sure to get their flu shots this year, in part because some Covid-19 and flu symptoms are similar. A flu shot reduces the likelihood that your symptoms (if you get sick) are from the flu. To make that flu shot effective, sleep specialist Matthew Walker, the bestselling author of "Why We Sleep," told CNN's Christiane Amanpour practicing "good sleep hygiene" is important.
