IJBM：午睡有助降血压

美国一项最新研究发现，如果工作压力大使人血压升高，不妨午睡片刻，这样会有助降低血压。

这项研究是美国阿勒格尼学院的研究人员完成的，研究涉及85名身体健康但精神压力较大的大学生。研究人员对这些大学生进行了精神压力测试，然后将他们分成两组，一组每天可以午睡约1小时，另一组没有午睡。

结果发现，尽管所有大学生在接受精神压力测试时，血压和脉搏跳动都有所增加，但对午睡了至少45钟的大学生来说，他们的平均血压要低于没有午睡的大学生。

研究人员指出，午睡有助降低因压力大而产生的高血压，从而起到维护心血管健康的作用。这一研究成果刊登在新一期《国际行为医学期刊》上。（生物谷Bioon.com）

Daytime Sleep Accelerates Cardiovascular Recovery after Psychological Stress

Ryan C. Brindle and Sarah M. Conklin

Background

Sleep restriction and poor sleep quality is linked with cardiovascular morbidity.

Purpose

The present study aimed to explore the influence of daytime sleep supplementation on cardiovascular reactivity.

Method

Participants (N?=?85) were generally healthy young adults and were randomized to a 60-min polysomnographically-monitored sleep condition or to a no-sleep condition. Participants then completed a standard three-phase mental stress reactivity task.

Results

Significantly lower mean arterial pressure means were found in the recovery phase of the stress reactivity task among participants that accrued more than 45 min of daytime sleep.

Conclusion

These findings suggest daytime sleep may offer cardiovascular benefit in the form of greater cardiovascular recovery from psychological stress. Further research should assess daytime sleep characteristics (time of day, length, and architecture) on cardiovascular response, in an effort to better understand its role as a possible recuperative agent against suboptimal nocturnal sleep patterns.
