Barometric pressure is measured either in millibars (mb) or inches of mercury (Hg). Readings below 29.80 Hg are often considered as low barometric pressure, whiles readings above 30.20 Hg are considered high; readings within the range of 29.9 Hg to 30.2 Hg are considered normal. Therefore, if you realize your home weather station’s reading is exceeding the normal readings, then you need to brace yourself for some changes in your body if you have any of the abovementioned health issues.
