Would a gloved hand warm up slower than a naked hand? I know that gloves (or socks, or clothing, anything) doesn't really make you warmer—instead, it makes heat loss slower, by improving insulation.
I was wondering, whether the converse is true. Let us assume I am outside and both of my hands get equally cold, and then I walk into a warm room indoors (uniform temperature in the room and outside, for simplicity's sake). Would my hands get warmer if I had gloves on, or gloves off?
I'm thinking I should take the gloves off, to maximise the heat transfer between the warm air and cold hands, but I was hoping someone else would confirm/refute this.
 A: Your body temperature is still greater than the room temperature, so you would still be losing net heat from uncovered hands.
By keeping the gloves on it traps the body heat coming from you inside the gloves and warms your hands up.
If the room was above body temperature, then the gloves would slowdown your heating, but not many rooms are that warm.
As @Ilja pointed out, this isn't always true.  It depends on the circumstances.  I made the assumption that the gloves you have on are also room temperature.
You can assume the inverse that they are at or below the temperature of your hands.  In that case wearing the gloves will be worse, as they will insulate your hands from the heat source; essentially taking away heat for themselves that could be going directly into your hands.
This reflects two situations, the first where you were outside without gloves and come inside and put gloves on that you find in the room.  The second scenario is where you wear the gloves outside with you for example and your hands still drop below room temperature.
A: Have you tried it? :) it's quite obviously so if you try it. Especially important for shoes, the feet can stay cold for a very long time if you do not put the shoes off.
There are two effects important here. First, your hands and feet are far below body temperature, so probably colder than any normal room in winter. And secondly the shoes (for gloves it's less important) have some heat capacity, and will keep you colder even if your skin were warmer than the room air.
