Huawei watches generally have the function of measuring pressure, and the normal range is 39 to 90. This range is determined according to the general physiological pressure change and equipment design. The measurement of pressure value can help users know their own stress level and remind them to take appropriate measures to relax and manage stress. In the range of 39 to 90, the value displayed by the watch can be considered normal. If the measurement results exceed this range, it means that the user's stress level is abnormal, and it is suggested that he consult a doctor or a professional for further evaluation and suggestions.
