Hello @nurseanne84 I love your comment..

Everything you said is true..!!

In this case:

I do not want to try it out because of the "exposure to cold" factor. In my experience, being exposed to anything cold would result in your muscles cramping especially on your legs.

If you don't want to try this one, it is not necessary ..!! This one is only when you have mastered the technique...

Thank you for your comment ...!!!
