I’m always colder in my mother’s house in Scotland (-5°C on cold days) than I am at my MIL’s house in the frozen Canadian wastelands (-40°C/F on cold days), because my mother will play games with thermostat to save money, where my MIL would simply die of exposure if the heating wasn’t on consistently for 6 months of the year.
There's also a very different type of cold close to the water. -40C will dry out your skin and make it feel like it's burning, but -5C in Scotland or on one of the Gulf Islands near Vancouver will make your bones feel frozen without good insulation.
