Sleep ‘Spas’ If you feel the necessity to go on something billed as an ‘insomniacs retreat and sleep disorders boot-camp spa therapy weekend’ you should understand that you usually sleep better when you are in relaxing environment, so the mere act of going to a spa for a couple of days and having massages, body scrubs, relaxing by the pool etc. will help you sleep better, temporarily. However your life is not one long spa weekend, so this improvement in your sleep should not be taken as evidence of effectiveness of the ‘sleep advice/therapy’ received. Only if when you go back to your normal life the advice helps you constantly sleep better can the advice be said to be effective (but then the expensive ‘boot-camp’ would not have been necessary as the advice would have worked without it).
