How to use this result
Sleep temperature advice is often quoted as one perfect number, but bedrooms behave differently. Some rooms hold heat, some collapse in temperature by morning, and some feel cold because of draughts even when the thermometer looks acceptable.
This planner compares bedtime and morning readings with the way the room actually feels. It then suggests one test: reduce retained heat, pre-warm then settle, or measure the overnight swing before changing bedding and ventilation together.
Use it with a simple room thermometer for several nights. The pattern is more useful than one isolated reading.
Run the tool, choose one change, repeat it for two or three nights, then compare the room notes. A repeated pattern is more useful than one perfect-looking number.
