"Relieves stress"? COMPLETELY! Initially, I sprayed this on my wrists and neck when I got home from work but soon found myself so relaxed I would fall asleep :) Now I spray it on at night before I go to bed for a restful nights sleep and to help improve my magnesium levels for the morning. There is a slight warning that a "tingling' sensation is normal. I did feel this. Its more of a slight burn or itch than a tingle (say like mint) but ABSOLUTELY nothing too apparent to stop using! I would recommend this to everyone including those who are anxious and have trouble sleeping.
