This is good advice. I learned Transcendental Meditation a while ago and found that it did relieve stress. I also found that when I was tired I would fall asleep instead of meditating since that's what my body needed. I try and do it when I first wake up in the morning for 20 minutes and again sometime before dinner. Sleep and exercise are also good at reducing stress, but I have definitely found that meditation helps me to relax and reframe my perceptions.
