  • Feel It? 4 Ways Barometric Pressure Affects Your Health

    May 06, 2019· Dr Cynthia Armand explains, “Our head is made up of pockets of air that we call sinus Usually, those pockets of air are at equilibrium with the atmospheric pressure When there’s a change in that atmospheric pressure, it creates a change in what you’re experiencing in your head and what’s going on in the air around you.
