close your eyes think of relaxing into that stage of nrem sleep the one where your body repairs itself [SEP] my daughter has tried these so far and says they feel good i know from first hand experience that the pearl style gel products are very rigid concerning their warming times and these are a little better and have cool and warm inserts with the aroma scented pieces that can be worn on either side so far several weeks now and liking themseems to help reaching all the known stages of the sleep cycle or just resting and relaxingwe do recommend this product and only wish they included a washable zippered pouch for all that comes with them
