My dad always jokes with me that if the temperature gets below 100F that I am freezing!
Well yeah he is right. I am so used to the temperatures being over or around 100F (what is that in Celsius…32C?). I have what is called “acclimated” to my environment. 
Yesterday and today the girls and I have been freezing…and it was only 68F/20C. I finally gave in and turned the heater on! Last night I slept with two fluffy blankets because it got down to the 50′s 
….how would I handle it if I was back home and it was snowing?!?!
Here is my heater turned on full blast this morning and I was sitting right next to it to warm up!
And this is what I am drinking to warm up…a huge mug of green tea and mint without sugar…because I am attempting to be sugar-free (we’ll see how long that lasts) 
Essalam Alaikum, I am also living in the desert and have found that my body is just now starting to adjust to it, meaning I’m freezing at night when I used to open my bedroom window at 50 something degrees. Subhan’allah it is indeed funny.
Wa Alaikum Salaam, hehehe….I wished that I had a fireplace last night…it got down to 16C….brrrrrr, LOL
