New York's Village Halloween Parade is an annual holiday parade and street pageant presented on the night of every Halloween in New York City's Greenwich Village.
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.
As air moves deeper into the alveoli that lie in direct contact with the blood vessels, it exchanges oxygen for carbon dioxide. While inspired air is cooling the lung tissue, the expired air adds some heat back to the cooled tissues on the way out of the lung. Cold air is very dry.
