What Fall Weather Does to Your Health

Fall can mean a lot more for your body than an influx of candy corn and pumpkin-spiced everything. The cooling air and changing weather patterns can hit your body hard, affecting everything from your blood pressure to how your fingers feel.

Those with certain conditions might feel a particular sense of dread after the autumnal equinox, as seasonal variations in temperature can spur all kinds of health problems.

One of the most obvious issues, affecting an estimated 50 million Americans: fall allergies. During autumn, ragweed is often the top concern, though in some parts of the country, tree pollen can cause problems at the same time, Stanley Fineman, M.D., of the Atlanta Allergy and Asthma Clinic, told weather.com. "[Those with fall allergies] need to be properly diagnosed, so they know exactly which one or both is triggering their symptoms," he said.

When barometric pressure, or the weight of the air pressing down on the surface of the Earth, changes, many people feel it acutely in their sinuses. If your sinus pressure just doesn't go away, it may be a sign of an undiagnosed seasonal allergy — so it's a good idea to get to your doctor.
