Why does the same high temperature forecast feel colder at home at higher altitude?

"When living in two places with different altitudes, the temperature in the two places is often the same in the weather forecast, but the higher the altitude, the colder it often feels"-the reason is that the water vapor saturation affects the evaporation of human skin moisture.

At higher altitudes, the water vapor is less, the water vapor saturation is low, the air is dry, and the water transpiration of human skin is easy (that is, sweat volatilizes more), so it will feel relatively cold.

At low altitude, there is more water vapor, high water vapor saturation and humid air, so it is difficult for human skin to evaporate water (that is, sweat evaporates less), so it will feel relatively stuffy.

This situation will also appear in the difference between coastal areas and inland areas-the same altitude, the same temperature, the coastal areas will feel sultry than the mainland.
