The core feature of a smart bed heater is its ability to regulate temperature. Studies show that the ideal sleeping temperature for most people ranges between 60°F to 67°F (15°C to 19°C). Traditional heating systems, like heavy blankets or old-fashioned heaters, can lead to overheating or drafts that disrupt sleep. In contrast, smart bed heaters maintain a consistent and comfortable temperature throughout the night. Many models even come equipped with settings that allow users to adjust the heat based on personal preference, ensuring that everyone can find their perfect sleep temperature.
