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.
This happens when the temperature of air is increased. Warm air molecules have more energy, so they move faster and create more pressure. Likewise, cold air has less energy, and therefore exerts less pressure on its surroundings.
