In a house with exterior basement insulation, the massive foundation wall is warm and slows down temperature changes (hotter or colder) in the basement. Hence, the basement is usually warmer than the rest of the house when the upstairs thermostat turns the furnace on and will overheat before the furnace is turned off.
Colder air tends to be denser than warmer air, and that means it sinks and pushes the hotter air up. A hotter upstairs can also be a lack of proper air ventilation. Furniture, like beds or dressers, may be blocking air ducts that allow air to flow freely throughout the upstairs.
Secondly, why is my basement so much colder than upstairs? The cause of the different temperatures is actually very simple. Warm air goes up and cold air goes down.
