Nowadays， most people are lacking of sleep， because part of them like to hang out at night and then stay up， or some of them are asked to work overtime. As a result， most people suffer from sub-health status. Getting enough sleep can guarantee both efficiency and our health. On March 21st， it is the World Sleep Day， which reminds people of the importance of getting enough sleep. Healthy lifestyle is the only way to help us to live a better life， so we need to plan regular timetable and do some exercise. No matter how much money we earn， if we are in poor health， we can’t enjoy a good life.

如今，因为有一部分人喜欢晚上出去、熬夜，或者有一部分人被迫加班，所以大多数人都缺乏睡眠。由此导致了很多人都处于亚健康状态。拥有足够的睡眠不仅能保证效率，也能保证我们的健康。3月21日是世界睡眠日，这提醒了人们充足睡眠的重要性。健康的生活方式才能帮助我们拥有更好的生活，所以我们需要规划好规律的作息时间以及运动。如果身体健康状况不好，不管我们挣了多少钱，都不能享受美好的生活了。
