Recent Research shows that even walks for 30-45 minutes 5 times a week improves immune function and also improves the bodies response to the flu vaccine.
Researchers from The Appalachian State University carried out research on subjects for 12-15 weeks and found that walking for 45 minutes at a brisk pace 5 times a week improved immunity, reduced occurrence of infections and reduced sick days.
So try and walk more, and have less sniffles! yet another one of the many benefits of physical activity. When the weather is as cold as its been think about getting a stationary bike or treadmill.
I use the treadmill after Jasmine goes to sleep and read food blogs on the laptop!
Or dance around with her LOL
