The other replies are exactly correct. I was diagnosed a few years ago, and this was my primary symptom.
I waited too long after that symptom on-set, though, and ended up in the ER with heart palpitations, shortness of breath, and flop-sweat.
...and lemme tell ya -- when an overweight, middle-aged white guy stumbles into the ER sweating and re-faced while complaining of chest pain, those nurses haul ass. I went from fully-dressed at the entry door to shirt off in a bed with an EEG hooked up in less than two minutes. There was an IV in within 4 minutes, and the first blood test was heading to the lab within 8 minutes.
Please don't let your symptoms go as far as I did. You are likely still at the stage where you could lose some weight and get rid of your symptoms. Though I lost 15 pounds very quickly after my diagnosis, and lowered my A1C from 7.9 to 6.2 in 3 months, I still have to check my blood sugar daily and be super careful of what I eat.

Evaporation, in ELI5 terms, is simply a molecule of water getting so excited that it literally jumps out of the container in which it is stored.
A puddle of water contains a bunch of water molecules which are all bouncing against each other and their container, but they don't have the energy needed to actually bounce out of the container. Then a (relatively) warm room or a little bit of sunlight provides some extra energy, and a molecule gains the extra energy needed to leap out of the puddle and into the air.
This can happen at any temperature above O C.
At temperatures below 0 C, as described in other posts, water molecules can skip the liquid phase and go straight from ice to vapor in a process called sublimation.
It all boils down (pun absolutely intended) to energy input.

So much this. There is not a single right angle anywhere in my house, except where the contractors added a new wall to separate a room into two distinct rooms. ...and it looks wrong because it doesn't match the rest of the angles.
