Blood pressure (BP) exhibits seasonal variation, with an elevation of daytime BP in winter and an elevation of nighttime BP in summer. The wintertime elevation of daytime BP is largely attributable to cold temperatures. The summertime elevation of nighttime BP is not due mainly to temperature; rather, it is considered to be related to physical discomfort and poor sleep quality due to the summer weather. The winter elevation of daytime BP is likely to be associated with the increased incidence of cardiovascular disease (CVD) events in winter compared to other seasons. The suppression of excess seasonal BP changes, especially the wintertime elevation of daytime BP and the summertime elevation of nighttime BP, would contribute to the prevention of CVD events. Herein, we review the literature on seasonal variations in BP, and we recommend the following measures for suppressing excess seasonal BP changes as part of a regimen to manage hypertension: (1) out-of-office BP monitoring, especially home BP measurements, throughout the year to evaluate seasonal variations in BP; (2) the early titration and tapering of antihypertensive medications before winter and summer; (3) the optimization of environmental factors such as room temperature and housing conditions; and (4) the use of information and communication technology–based medicine to evaluate seasonal variations in BP and provide early therapeutic intervention. Seasonal BP variations are an important treatment target for the prevention of CVD through the management of hypertension, and further research is necessary to clarify these variations.

血压（BP）呈现季节性变化，冬季白天血压升高，夏季夜间血压升高。白天BP的冬季升高主要归因于低温。夏季夜间血压升高的主要原因不是温度；相反，它被认为与夏季天气导致的身体不适和睡眠质量差有关。与其他季节相比，冬季白天 BP 的升高可能与冬季心血管疾病 (CVD) 事件的发生率增加有关。抑制过度的季节性血压变化，特别是白天血压的冬季升高和夜间血压的夏季升高，将有助于预防 CVD 事件。在此，我们回顾了有关 BP 季节性变化的文献，并且我们推荐以下措施来抑制过度的季节性血压变化，作为管理高血压的方案的一部分：（1）全年的办公室外血压监测，尤其是家庭血压测量，以评估血压的季节性变化；（2）冬夏前降压药物的早期滴定和减量；（3）室温、居住条件等环境因素的优化；(4) 使用基于信息和通信技术的医学评估血压的季节性变化并提供早期治疗干预。季节性血压变化是通过管理高血压来预防 CVD 的重要治疗目标，需要进一步的研究来阐明这些变化。
