Assuming no wind 60 degrees outside feels decently warm however when the ac is set to 60 degrees I feel like I need a jacket.

The air inside most modern houses, at least in the US and Canada, isn’t just cooled, but *conditioned*. This means the humidity is kept comparatively-low, especially compared to humidity you can encounter outside your home.

60 degrees in high-humidity air *’feels’* hotter than 60 degrees in low-humidity air, because when the air is humid your body’s ability to cool via evaporation ((you sweat onto the surface of your skin, the liquid sweat transfers some of your body heat to itself, then evaporates into the atmosphere) is inhibited.

For your daily dose of nightmare fuel, this is why scientists are freaking out about “wet bulb temperatures”: when the relative humidity of the air hits 100%, your bodies ability to cool itself via evaporation is effectively negated, and if the temperature of the air is high enough (35 °C (95 °F)) at the same time, your body starts to ‘*absorb’* heat from the surrounding environment, rather than shedding it.

With climate change, we are likely going to start seeing more and more deadly wet-bulb temperatures
