Sleep accessories are items designed to enhance the quality of sleep and promote relaxation. Common examples include pillows, mattress toppers, and sleep masks. These products can help provide comfort, support, and a darker environment, which are essential for a good night's rest. Other popular sleep accessories include white noise machines and aromatherapy diffusers. White noise machines create soothing sounds that can mask disruptive noises, while aromatherapy diffusers release calming scents, such as lavender, to help ease stress and anxiety. Together, these accessories contribute to a more restful and rejuvenating sleep experience.
