Does exposure to cold temperature increase your metabolice rate?
For the first question, here is my explanation. Our body has thermoreceptors within the hypothalamus will receive signals when our sensory nerves detects a drop in the environmental temperature. then our cells will be directed to produce more heat by several mechanisms such as erecting our body hair and vasodilation. So, our metabolic rate will rise. However, if the temperature approaches below the optimal operation rate of enzyme activities, our metabolic rate will decrease BUT the metabolic activity will persist anyhow. This is known as the impeding factor. For the second question, i will say no. Your body will have made the cold drink to achieve thermal equilibrium when flowing through the alimentary canals. The amount of liquid you can imbibe is comparatively easier to be equalised with the body’s temperature, so no difference of temperature occurs. Hence, no difference in metabolic rate.
