Why am I always cold inside but not out?

Could it be the freedom you have outside? the extra activities that keep you warm? also, some people keep their inside thermostats so low, its hard to tell the difference, in temperatures, from the outsdie to the inside.

When you are inside, you are often sitting still. You are not moving and generating heat.

My guess would be in agreement with Marina. It may be that you’re active outside and less active inside.

I get that problem with my feet indoors. Maybe a circulation problem. Outdoors, moving around especially on cross-country skis, it doesn’t seem to be a problem. I use tick wool socks, even in bed, helps a bit.

If your basal temp is uncomfortably cold in a temperate environment, it might have something to do with the lack of movement on your part. In order for the blood to warm your body, it must circulate.

It might also have something to do with your diet. I work in an office environment with a lot of women. A couple of years ago when the low carb diet became popular, I noticed a lot more of them complaining of being cold, accompanied by some complaints of late afternoon fatigue and headaches. Those that did their homework soon went to a balanced diet and found they were no longer cold, had more energy, and less headaches. Carbohydrates are nearly pure energy and, like most fuels, burning them creates heat. The problem arises when one eats too many carbs to burn, and they are stored as body fat for future use. If not used, the body has a way of creating more storage space. (One pound of body fat requires three miles of capillaries. This eventually will affect the heart.)

The winter diets of many northern peoples, such as Lapps and Mongols are nearly exclusively protein based. In other words, they eat a lot of meat. Those that don’t eat a lot of meat tend to suffer the effects of cold more than others. Protein builds new cells and repairs damaged ones. This process creates sustained release heat and the surplus isn’t stored as readily as body fat.
