A very simple but extremely important tip for all Swedish Relaxation therapists:

Keep in contact with your patient throughout the entire session!

I was taught this in massage school, and through my years of providing massage therapy have found this to be extremely effective during relaxation treatments. 

Why?

When a client is beginning to relax during a treatment, every time you lift your hands off and place them back on throughout the session, you cause an ever so slight "shock" to your clients body. This "shock" tells their brain to engage and acknowledge this feeling.  

The more you can keep a fluid movement and constant touch with at least 1 hand throughout the entire treatment, you client will have a more relaxing and calming experience.
