Mind-body therapies are a waste of time

It is a well-known fact that mind-body therapies are becoming more popular every day all around the world. In my opinion, this may be because they are not a waste of time but on the contrary, they are truly successful.
First of all, most of mind-body therapies make yourself feel good, relaxed and healthier, and that's never a waste of time. The hours you spend doing a mind-body therapy are totally worth since then you will work and live muck more calmly.
Secondly, it has been demonstrate by many studies that when you suffer from an illness these mind-body therapies help you feel better. They won't cure your disease, for that you'll have to go to the doctor, though will surely reduce your harm. Moreover, it's a way of having new experiences and meeting pople, which is always very comfortable.
In conslusion, I think that mind-body therapies are not a waste of time because the time it would take you not to feel stressed if you didn't practise them might be much more longer.
