请问人的睡眠时间是多久?成年人睡眠时间标准「解析」

正常成年人夜间睡眠的时间一般是7-8个小时,青少年需要9-10个小时,儿童大概需要12个小时,婴幼儿需要超过14个小时以上的睡眠时间。成年人对睡眠需求时间并不完全一样,有少部分人夜间睡眠时间只在4-5个小时,这样的人被称为短睡者。虽然睡眠时间短,但是深睡期和正常人差不多,也就是说虽然睡眠时间少,但是减少的是浅睡眠和做梦期,而对于精力和体力恢复最重要的深睡期是够的。所以这样的人第二天也不会觉得累,或者说没有睡好。还有对睡眠需求时间长的,晚上可能需要9-10个小时,甚至10个小时以上的睡眠时间。所以对于睡眠来说,睡眠时间并不都是一定的,睡眠主要是为了让第二天能有充沛的精力进行工作和生活。如果第二天有神清气爽的感觉,说明头天晚上的睡眠时间是足够的,不必纠结一定要睡多长时间。
成年人,是指年龄在18岁及以上的人群。成年人的工作和生活压力较大,因此睡眠质量尤为重要。
据专家研究,成年人每晚需要7-9小时的睡眠时间,以保证身体和大脑的正常运转和健康发展。然而许多人由于各种原因睡眠时间不足,这对健康的影响是不可忽视的。
缺乏充足的睡眠,容易导致身体疲劳、头痛、焦虑抑郁、记忆力下降等不良反应。同时,长期睡眠不足还可能增加患心血管疾病、糖尿病等疾病的风险。
要保证充足的睡眠,我们需要注意以下几点:
1. 规律作息。每天固定的睡眠时间可以让身体有节律地进行休息和恢复。同时也要保持良好的饮食习惯和生活习惯。
2. 调整睡眠环境。睡眠环境对睡眠质量有着很大的影响。应该保持安静、舒适、通风的环境,并控制好室内温度和湿度。
3. 放松心情。过度的紧张和压力会影响睡眠,因此我们需要学会正确认识和处理自己的情绪。可以听音乐、泡澡、读书等放松方式来帮助睡眠。
Normal adults need 7-8 hours of sleep at night, teenagers need 9-10 hours, children need about 12 hours, and infants and young children need more than 14 hours of sleep.
There are also long-term sleep needs, which may require 9-10 hours of sleep at night, or even more than 10 hours of sleep. Therefore, for sleep, the sleep time is not always fixed. Sleep is mainly to enable you to have sufficient energy for work and life the next day. If you feel refreshed the next day, it means that you have enough sleep time the night before, and you don't have to worry about how long you must sleep.
Adults' sleep requirements are not exactly the same. A small number of people sleep only 4-5 hours at night. Such people are called short sleepers. Although the sleep time is short, the deep sleep period is similar to that of normal people, that is to say, although the sleep time is small, the light sleep and dreaming periods are reduced, and the deep sleep period, which is the most important for energy and physical recovery, is sufficient. Therefore, such a person will not feel tired the next day, or not sleep well.
