ELI5: Why does it feel colder inside in the winter even though the thermostat says the temperature is the same?
gpt
Humidity plays a big part in temp perception.  In the winter, outside colder air cannot hold the same amount of humidity as hotter summer air, so typically your house, while the same temp, has less humidity.  Even if you have a humidifier, it's tough to match the potentional summer air humidity.  That difference eventually makes it into your house.

The lower the humidity, the more moisture evaporates on your skin, making you feel cooler despite the temp at the thermostat saying the same.
