Transcript

To boost your immune system, maybe you just need to get enough sleep— or is that a total myth? Fact or fiction: If you don’t get enough sleep it can impair your immune system. Believe it or not, we didn’t know for certain either way until this year.
Researchers dripped virus into people’s nostrils—the common cold virus. Now you’d think if someone squirted virus right into your nose you’d definitely get sick, but no, it depends on your immune system. Someone with a cold can sneeze dead in your face, but if you have a good enough immune system you won’t get sick.
So in the study, did it depend on how much sleep they’d been getting? Fact, or fiction?
Fact, in fact those getting enough sleep were 3 to 5 times more likely to beat the virus.

    Can you recommend anything for helping to sleep through the night & keeping your energy up during the day? Been vegan since October and both hubby and I cannot stay awake. After 7 hours we’ve been up we zonk out. We take b12 like you recommend and we take d also.

      Being vegan in general does’t necessarily cut it. This was happening to me as well when I changed to a vegan diet. Make sure your getting the right combinations of foods, because if your missing key nutrients your body wont be keep itself energized! I was having to little salt and sugar. As soon as I added himalayan salt and more fruits my energy boosted!

    I have a really bad cold.  What can I do to make it go away as soon as possible?  The only medicine type thing I’ve been taking is cough drops because my sore throat is super painful & won’t go away!  I know it’s my fault that I got it.  I totally brought it on by staying out too late & drinking & smoking the green stuff.  It’s something I shouldn’t be doing right now anyway.  My body is mad at me now.  I’m very busy though & want to know what to do.  At the moment I’m so sick I can’t get out of bed:(  Thanks for any info you have on what I should be eating etc. to get better.  Thanks again!
