How can you feel cold?
That's exactly it. People here in Miami have a knee-jerk reaction that anything not hot is "cold". That's why people here think 70 F for a daytime high is cold. Because it's not hot, not because it's actually cold.

That's true.

However, 77 °F inside a house should be warm enough to dress lightly and not to use heavy blankets at night.

I don't get how people can have their homes at 82 °F or above, that's uncomfortable (at least for me). It feels like you'd need to go outside to take a breath of fresh air every now and then, but that would be a nightmare, if the temperature above is much higher (like 90 °F or above).

I think 77 F inside in uncomfortably warm, especially when sleeping at night. Granted I'm a bigger dude than average (6'1, 220 pounds) so that's probably why.

80 degrees is not warm if there is a wind and no sun. Remember the only reason you are 'warm' in 80 degrees is the air is a poor conductor. Your body produces heat, the air-body temperature gradient combined with how poor of a conductor air is, prevents it from absorbing enough heat and you begin to feel warm.

Increase the wind, increase the convection, eventually even you and Alex will be cold in 80 degree air. I guarantee it, 100%. It is basic physics.

I have never felt cold at 80 F. Regardless of how windy or sunless it was.

Well then you defy the law of physics.

No, feeling "cold" at 80 F defies physics. We're not cold-blooded lizards that need constant sun and heat to be comfortable. We produce plenty of our own heat.

80 degrees is colder than 98 degrees, if your body cools to 80 it will die.

What's more between the ambient air, and the human body, the ambient air can be approximated as an infinitely large heat sink, not being warmed by absorbing the heat from the human

With increase wind, means increased convection, means the rate of which you lose heat to the air increases, if we keep increasing the wind, we reach a point where your body produces less heat than it loses, if I remember right, that's around 20mph.

Yeah you're right. When it's 75 degrees tonight, I'll make sure to lock all my windows so the bitterly cold air doesn't come in and freeze me. I'll keep my house at exactly 98.6 degrees.

Go in chilly water then get out on a low dewpoint, windy day and you may feel cold for a while.
