南昌高校宿舍夏季睡眠环境现场调查与统计分析
Field investigation and statistic analysis of summer sleep environment of university dormitories in Nanchang
摘要：
以南昌某高校学生宿舍为研究对象,测量了夏季夜间室内温度、相对湿度、风速、CO2浓度等环境参数,并对26名受试者睡前和醒后的主观环境评价及睡眠质量进行了调查。利用统计学方法对测量和调查结果进行了分析,结果表明:睡眠状态与睡前清醒状态热中性温度都为25 ℃,睡眠状态有比清醒状态更宽的可接受温度范围;宿舍夜间CO2浓度较高,醒后室内空气品质满意度比睡前显著降低,应适当增强通风;睡眠期间较高的室内温度、相对湿度和CO2浓度都会导致睡眠质量下降;夜间凉爽且通风良好的室内环境更有利于提高学生睡眠质量。
Abstract：
Taking the student dormitories of a university in Nanchang as the research object, the environmental parameters such as indoor temperature, relative humidity, wind speed and CO2concentration at night in summer are measured, and the subjective environmental evaluation before and after sleep and the sleep quality of 26 subjects are investigated. The measurement and investigation results are analysed by the statistical methods.The results show that the thermal neutral temperature of both the sleep state and the awake state is 25 ℃, the sleep state has a wider acceptable temperature range than the awake state. The CO2concentration in the dormitories is higher at night, and the satisfaction of indoor air quality after sleep is significantly lower than that before sleep, so the ventilation should be properly enhanced.The higher indoor temperature, relative humidity and CO2concentration during sleep will lead to the decline of sleep quality. Cool and well-ventilated indoor environment at night is more beneficial to improve the sleep quality of students.
