When summer arrives, hypertensive patients often find a decrease in blood pressure compared to winter when measuring their blood pressure during the day. Many hypertensive patients believe that during the summer, their blood pressure is low and they can reduce their medication and dosage on their own. Dr. Li pointed out: In summer, the blood pressure will be higher at night. Unauthorized drug reduction is prone to stroke and other cardio cerebral Vascular disease. Stable control of blood pressure at night is the focus of blood pressure management in summer.
Why can't medication stop when blood pressure drops in summer?
Human blood pressure varies regularly in different seasons and at different times of the day. Research shows that in summer, the daytime blood pressure of patients with hypertension will be lower than that in winter. "This may be because people sweat more in summer and drink less water, which leads to the reduction of blood volume. In addition to the rule of" Thermal expansion ", blood vessels tend to expand in hot days, and these two factors will lead to the reduction of blood pressure.
Research has found that nighttime blood pressure in hypertensive patients is actually higher in summer than in winter. High blood pressure in summer evenings may be related to decreased sleep quality and mental excitement. In addition, the reduction or discontinuation of anti-hypertensive drugs is also an important reason for the increase in nighttime blood pressure.
Stable control of nighttime blood pressure is a key aspect of summer blood pressure management. User friendly portable blood pressure monitors are popular and useful and hypertension patients need to monitor their blood pressure more in summer. After symptomatic Hypotension occurs, cardiovascular specialists should decide whether to adjust the medication plan rather than reduce the antihypertensive drugs without authorization. In addition, patients should choose long-term medication that is administered once a day and lasts for 24 hours to achieve stable blood pressure reduction day and night.

(2) The temperature difference between indoor and outdoor air conditioning should not be too large
It is advisable to use an air conditioner with a temperature difference between indoor and outdoor temperatures not exceeding 5 ℃. Even if the weather is hot, the indoor temperature of the air conditioner should not be lower than 24 ℃.
2. It is advisable to have a light diet and eat more vegetables and fruits
