It Can Trigger Cardiovascular Issues. The cold air makes your body work overtime, especially the lungs and heart, because they work in unison to keep that warm blood circulating without skipping a beat. This can cause blood pressure to rise, as blood vessels constrict so they can get back into the heart.
When the air temperature is close to or warmer than normal body temperature, cooling of the body becomes more difficult. Blood circulated to the skin cannot lose its heat. Sweating then becomes the main way the body cools off.
