Why does your temp go down when the heater is on and when its not on it gets a little hot?

When the heater is on, it typically warms the air in your environment, causing your body to regulate its temperature by dissipating heat, which can sometimes lead to a feeling of cooler skin or a lower core temperature. Conversely, when the heater is off, the ambient temperature drops, prompting your body to conserve heat, which can make you feel warmer as your body works to maintain its core temperature. This contrast in ambient temperature affects how your body perceives warmth and coolness.
