1. Sprinkle just-washed sheets and pillowcases with lavender water. The scent has been shown in studies to promote relaxation, which can lead to better sleep.
2. Buy a new pillow. Studies show that pillows with an indent in the center can enhance sleep quality and reduce neck pain. Also, try a "cool" pillow -- one containing either all-natural fibers or a combination of sodium sulfate and ceramic fibers that help keep your head cool.
3. Eat a handful of walnuts before bed. You'll be giving yourself a boost offiber and essential fatty acids along with the amino acid tryptophan -- a natural sleep-inducer.
