美国研究人员的研究发现每天睡眠不足6小时的人,其患感冒的风险比睡眠7小时以上的人高出4倍多。美国的研究人员调查了164名志愿者,以了解他们承受的压力、性格和吸烟、饮酒等情况。随后,研究人员利用腕式感应器监测这些志愿者每晚的睡眠时间和质量,总共持续一周时间。研究表明,与每晚睡眠超过7小时的人相比,每晚睡眠不足6小时者患感冒的风险会高出4.2 A study by US researchers found that people who slept less than 6 hours a day had a 4 times greater risk of getting a cold than those who slept for more than 7 hours. Researchers in the United States surveyed 164 volunteers to understand the pressure, character and smoking, drinking and other conditions they were exposed to. The researchers then used wrist sensors to monitor the nightly sleep and quality of these volunteers for a total of one week. Studies show that people who sleep less than 6 hours a night risk a cold more than 4.2 who sleep more than 7 hours a night
