When someone stands next to a fire, they essentially create a barrier, or shadow, that blocks the surrounding air from being drawn in, creating another low-pressure zone, Anderson explained.
"And what ends up happening is the hot air that's rising ends up being brought into this vacuum, so it gets pulled toward you," he said. "And with the head at the top of your body, the smoke is drawn into your eyes."
