Longer and Deeper Hi Tech Power Napping: Falling into deeper sleep for a longer nap
(Reklamlänk)
If you are stressed out, and need a nap, but can't sleep, this program is for you. You just lay back, and listen with headphones, keeping the volume low. After about 4 or 5 minutes you will fall asleep, and be awakened about 50 minutes later. No effort is required. It works!
