If you have never had a professional massage, the unknowns can be more stressful than the knots.
Before
Arrive fifteen minutes early. You will fill in a short form, change into a robe and have a tea.
During
You are covered with a sheet the whole time; only the area being worked on is uncovered. Tell your therapist if the pressure is too much or too little. They want to know.
After
Drink water, skip the gym and expect to sleep well.
Talking is optional. Most guests say hello and then nothing at all.
