Why do we feel cold?

Why do we feel cold in Winter?

If your answer is, “because of the low temperature.” You are right but I want you to think deeper and reason more. Why don’t our body adjust and stay normal though the temperature of the environment may change. Hundreds of poor people die every winter due to the extreme cold. Can there be a way our body can adjust with the temperature of our environment so that we need no much warm clothes to fight the winter? Well, that’s another question.
Yes, it is cold due the decrease in the temperature of the environment. But should we necessarily feel cold? The normal temperature of our body is 37 degree Celsius or 98.6 degree Fahrenheit. Our body is always in direct contact with the environment around us, so the change in the environment directly effect our body. When the temperature of the environment is lower than our body temperature, our body transfers heat to the environment which results to the decrease of our body temperature.  And our body does not transfer our blood towards our skin, it keeps it slightly below the skin so that the warm blood is available for other important organs inside the body. This results the fall of temperature of the skin, and give a sense of feeling cold. Thus the skin become dry. This process is called Vasoconstriction, which is the narrowing of the vessels. Further falling of temperature will result in shivering of body producing mechanical vibration to generate heat in order to cut down the loss of heat from our body. That is the answer of “Why we shiver when w feel too cold?” That’s a bonus question for today. Thanks for reading.
