Sleeping aids are items that can help people get a better night's sleep. An eyeshade is an item that is worn over the eyes to block out light, usually in the form of a mask. A COT is a small bed or sleeping area, often used for camping or other temporary sleeping arrangements. A PILLOW is a soft cushion used to support the head and neck while sleeping. Earplugs are small pieces of foam or wax that are inserted into the ear to block out noise. Finally, a clear conscience is a feeling of peace and contentment that comes from knowing that one has done nothing wrong. All of these items can be used to help people get a better night's sleep.
