Believe it or not the air that you breathe has a lot to do with how relaxed or not relaxed you are as a person and going on one of these so called walking holidays can really help you out with this.
Basically most people will go to a higher place when they are out on a walking holiday and as everyone will know that the higher you are the cleaner the air is so walking up those mountains may feel like it’s a bit bad on the lungs but in fact it is really just giving them a good clean out for you which if your like me is well needed. I will say that if you are a smoker you will struggle with this, I am not but one of my friends I went with is a heavy smoker and the first couple of days were very harsh on him.
This of course is just one of the reasons, and there are so many other reasons too.
