Location: Low Pressure Areas of high and low pressure from weather maps are an indicator of the ElectroMagnetic Fields in a given location. EMF Sensitive individuals should consider exploring regions which experience a large proportion of days with low atmospheric pressure throughout the year. Air pressure has been known to affect human health, for example, through the popping of your ears on an aircraft (USA Today, Understanding air pressure) This can be particularly problematic for people with sinus problems. Note that while atmospheric pressure decreases with altitude, there is not necessarily a corresponding decrease in ElectroMagnetic Fields as cellular towers are often situated at the top of mountains. Areas of high and low pressure affect weather patterns and change over time. Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of air above that surface. Weather Fronts (USA Today) Isobar map (Europe) (Windfinder)
