We usually wear Sweater to be comfortable in extreme cold of winter. But do you no science which actually make ourselves comfortable in cold season?
our body contains natural heat which continuously exchanged with surrounding. We need to just prevent this heat exchange process so that heat content in our body increases which ultimately create sustainable environment in winter season. As a mechanical engineer, we know that cotton works as an insulator. Our sweater is prepared with cotton fiber and after wearing it an insulation is created around our body. This cotton insulation prevents natural flow of our body heat with cold air. So friend, sweater doesn’t stop cold current of air to be in contact with our body but it actually stops our body heat to flow away .
