Blood pressure is normal in summer and high in winter, not necessarily high blood pressure, specific or according to the results of blood pressure measurement to judge.
Normal systolic blood pressure is 90~139mmHg, diastolic blood pressure is 60~89mmHg. Blood pressure is normal in summer, and high in winter, but within the normal range is also normal blood pressure, not considered hypertension.
In winter, it is recommended to measure the blood pressure for three consecutive days in the same time period, and each time the blood pressure is measured, the diastolic blood pressure is higher than 90mmHg and/or the systolic blood pressure is higher than 140mmHg, which can be diagnosed as hypertension.
It is not possible to determine whether an organism has hypertension solely on the basis of seasonal changes. High temperatures in summer will cause blood vessels to dilate, the pressure on the vessels will be less, and the blood pressure will be lowered or within the normal range. Low temperatures in winter cause blood vessels to constrict and the pressure on them is greater, so blood pressure in winter is higher than that in summer.
If you suspect that your blood pressure is abnormal, it is recommended that you go to the hospital to have it measured by a professional doctor.
