Given that stress is linked with illness, it might be no real surprise to learn that a positive outlook can have health-giving effects. At the very least, positivity spares us some stress but it seems to also have immune-boosting effects, as you can see below.
I’ve been thinking about this a lot recently. I’ve made an observation that when people learn a lot about health and nutrition, even though they enjoy better overall health when they act on their knowledge, they tend to get more colds. Of course this doesn’t apply to everyone but you might spot yourself if it does apply. And I have to admit, I went through that phase myself.
