Hopefully it's all common sense:

• Your massage is done clothed, so wear lose, comfortable, soft clothing – not too many buttons or zips.
• Do not drink alcohol or take recreational drugs on the day.  Try to come with a fairly empty stomach (drinking is fine).
• If you have a fever, please call to rearrange your massage.
• If necessary, consult your GP or health professional to check that massage is safe, or if there are any special requirements.  You need to do so if you have a medical condition/health problem, are undergoing medical treatment, feel acute pain, are pregnant,  or have any reason to believe massage may be harmful.
