Spring blood pressure fluctuations are related to temperature changes and hormone level fluctuations in the body. In spring, the temperature is relatively cold, and the temperature difference between day and night is large. Higher temperatures during the day will cause blood vessels to diastole and lower blood pressure, while lower temperatures in the early morning and at night will cause blood vessels to constrict and blood pressure to rise, resulting in greater fluctuations in blood pressure overall. On the other hand, in spring, the body’s secretion of some hormones that cause blood pressure to rise increases, such as dopamine, adrenaline, etc. The hormone secretion is pulsatile, which can lead to a transient rise and fall of blood pressure and blood pressure fluctuations. For hypertensive patients, in the spring need to insist on taking antihypertensive drugs, do a good job of keeping warm, if the blood pressure fluctuation is large or even the emergence of dizziness and headache and other symptoms, timely to the hospital, follow the doctor’s instructions to adjust the antihypertensive program.
