Irregular sleep schedule linked to high blood pressure

睡眠模式不规律的人患高血压的几率比那些坚持规律作息的人高得多, even when they get the recommended amount of sleep each night, new research suggests.

The study, published Tuesday in the journal Hypertension, 研究发现，周末睡懒觉的人，或者在一周内改变睡觉和起床的线上电子游戏飞禽走兽的人，患高血压的可能性要大得多, also known as hypertension, than those with more consistent sleep routines.

"This indicates that people may need to consider not only how long they sleep, 但也要认识到保持规律的睡眠线上电子游戏飞禽走兽表对最佳心血管健康的重要性," said senior study author Danny Eckert, 阿德莱德睡眠健康研究所所长，阿德莱德弗林德斯大学医学和公共卫生学院教授, Australia.

The American Heart Association recommends 成年人每晚睡7到9个小时，以促进心脏和大脑的最佳健康. 这一建议是基于先前的研究，该研究发现，平均每晚睡眠线上电子游戏飞禽走兽少于6小时的人患高血压的风险要高得多, obesity, cardiovascular disease and premature death. Likewise, 那些睡眠过多的人——每晚平均超过9小时——患高血压的风险更高, stroke, Type 2 diabetes and death.

这项新研究的作者指出，之前的研究调查了睡眠线上电子游戏飞禽走兽与睡眠线上电子游戏飞禽走兽之间的联系, 睡眠线上电子游戏飞禽走兽表的夜间变化和高血压依赖于几周内报告的数据.

In the new study, researchers looked at sleep patterns over a nine-month period for 12,287 adults with and without high blood pressure from 20 countries. Participants were predominantly middle-aged men who were overweight. Data were collected from July 2020 to March 2021. 该分析包括每位参与者平均181晚的睡眠数据和29个血压读数.

该研究将高血压定义为收缩压(上限)读数为140毫米汞柱或更高，舒张压(下限)读数为90毫米汞柱或更高. (美国心脏协会和美国心脏病学会将高血压定义为收缩压130或更高，舒张压80或更高，并长期保持在高位.)

研究人员使用放置在床垫下的设备来测量睡眠线上电子游戏飞禽走兽(人们入睡和醒来的线上电子游戏飞禽走兽)和持续线上电子游戏飞禽走兽. 他们发现，就寝线上电子游戏飞禽走兽变化90分钟或更长线上电子游戏飞禽走兽的人患高血压的几率增加92%, compared to those who stuck to a regular bedtime. 但即使是那些每晚就寝线上电子游戏飞禽走兽变化略超过30分钟的人，患高血压的可能性也要高出32%.

"This is a relatively modest level of sleep timing variability, given that people often stay up late on the weekends," Eckert said.

Sleeping late also was associated with higher odds of high blood pressure, but less so than not getting to bed on time. Waking up 43 minutes later was associated with a 9% increase.

As prior studies have found, 新的分析还表明，高血压与睡眠过少或过多之间存在联系. 睡眠线上电子游戏飞禽走兽少于7小时或超过9小时的人患高血压的可能性要高出20%-30%. 每晚睡眠线上电子游戏飞禽走兽相差两小时或更长线上电子游戏飞禽走兽的人患高血压的可能性比每晚睡眠线上电子游戏飞禽走兽相差不到一小时的人高85%.

对睡眠模式进行为期9个月的研究，可以提供更稳定的数据集，从而得出关于睡眠如何影响心脏健康的结论, said Dr. Reena Mehra, 俄亥俄州克利夫兰诊所睡眠障碍中心的医学教授和睡眠障碍研究项目主任. Mehra was not involved in the new study.

“如果你只考虑几周的线上电子游戏飞禽走兽跨度，那线上电子游戏飞禽走兽窗口就小得多了，”她说. “如果一个人的生活中发生了一些不寻常的事情，那就会影响研究结果. Whereas if you look at sleep patterns in totality over a span of months, that gives you a better picture of sleep-wake habituality."

虽然工作安排和其他承诺有时会让你很难保持规律的睡眠线上电子游戏飞禽走兽, 研究结果证实，人们需要“尽可能注意睡眠”," Mehra said. "Do the best you can to get consistency."
