Hello Sir/Ma'am, I have been noticing that I feel cold more than other people. Like even if there is slight drop in temperature or if it rains or if I am sitting under fan for a long time or if I am in AC for a long time I feel way too cold where most people don't feel that cold and it is normal for them. Can you please tell me as to why I feel so much cold, is it some blood problem, some vitamin problem or it is something else. Kind Regards, Manas.
