How can the brain tell if something is hot?
The skin, including the skin on your hands, has thermoreceptors that send messages to the brain about temperature. However, they respond to CHANGES in temperature, not temperature itself. So, if you come in from the cold, all surface temperatures will feel very warm, but gradually as you warm up, the surfaces will seem neutral. And, think about what happens when you put your hand in a lake on a hot day - it feels really cold, but if you jump in, eventually your skin will adjust to the temperature. Now, if the surface is burning hot or freezing cold, the pain receptors, not the thermoreceptors, in your skin react.

Do you have hot and cold flash when you are pregnant?
I am pregnant with our fourth and have hot and cold flashes. I am 40.4 years of age. I noticed that with our first child at 32 that I had more hot than cold flashes.

What does it mean if your ears are cold?
It's different in different cases! Here are some:If you have just washed your hands, used a cleaner for your hands, have touched water, have been swimming, or been doing anything to do with something cold, then you touch your ears and they are cold, it really doesnt mean ANYTHING. Now if you KNOW you have a fever, I'm not wrong, you just are sick... you probably just touched something cold when you are sick JUST to prove me wrong SOMETIMES!!!If your ears are cold when you have just woken up, been laying around, or some other reason when you have been around stuff ROOM TEMPERATURE you may have a low grade fever! You may not but it usually works for me!If you have been touching or around something HOT and you touch your ears it is because of the hot thing. It like backfires to make your nerves think the next thing you touch(skin, glass, floor, ect.) feel cold! Your body is so used to the warmth when it hits something, it feels cold!
