Icelanders manage to sleep comfortably during cold nights without radiators by using multiple thin blankets for insulation. They often use eiderdown duvets, known for their exceptional thermal properties. Preparing for sleep includes relaxing in geothermal pools, and they utilize blackout curtains for complete darkness. Layering bedding effectively retains body heat, and additional blankets can be placed strategically to warm specific areas. Maintaining a consistent sleep schedule is also important, with apps available to track sleep cycles.
