Whenever someone tells me that glucose is the preferred fuel because we burn it first, I tell them that we burn alcohol before anything else. Using that logic, we should all be hocked up on liquor 24/7 . What makes real sense though, is that the body will metabolize the most toxic fuels first.
Some tips on electronics in cold: 1  Most electronic components are not damaged by ânormalâ cold temperatures. 2  Condensation can be a problem, if the temperature cycles between warm and cold with humidity.  Batteries lose capacity in cold (battery powered devices might not work in the cold)
While step1 naturally makes one feel cold, step2 leads to rapid loss of heat from body owing to higher temperature difference between body and surrounding, which also makes one feel cold. This in a nutshell can be the simplified explanation.
