Running is good for a lot of things. We already know that, right? Well, here’s a little on the positive aspects of running.

How exercise may help us fight colds

Have you ever noticed that fit people are sick less often? You’re not imagining things.

Working out could help us fight off colds and other infections, according to a timely new study. The study, which found that regular exercise strengthens the body’s immune system in part by repeatedly stressing it, was conducted in animals. But the results most likely apply to people, the researchers say, and could offer further incentive for us to remain physically active this winter.

Is running good for your knees?

I’m sure we’ve all experienced people telling us that we’re ruining our knees. The interesting thing I’ve noticed recently is that, lately, people who are younger than me will say this while complaining how their knees ache. What’s up?

There has been some research suggesting that, much like stressing our immune systems to build them up stronger and stressing our muscles to build them up stronger, running can do the same for various structures of our joints.

Well, here’s another study that attempted to address a possible reason running might be good for the knees. Unfortunately, the results were inconclusive. There were some interesting results but there simply wasn’t enough data to say anything conclusively.

That said, we already know that, regardless of what your non-running friends tell you, running is definitely good for your knees. So keep it up.
