Good sleep helps you get enough rest and stay energetic. While you sleep, your brain processes the information it has received during the day and forms memories. Also, your body does lots of repair work—refreshing tired body parts, reducing pains and cleaning up waste in your body. Today, people sleep for a whole night. However, diaries, books and other records from the 15th to 17th centuries suggest people used to sleep differently. People would go to sleep between 9 pm and 11 pm for a couple of hours. They would wake up for a while, and during this period they might read a book, visit a neighbor or do some chores. Afterwards, they would lie down for the second sleep, which lasted until morning. Researchers think it was the invention of the light bulb in 1879 that changed this. Electric lights meant people started staying up later, so when they finally went to bed, they slept until morning. The Industrial Revolution (工业革命) also changed how people slept. Starting in the 18th century, people moved from the countryside to the city to work in the factories. People had to get up and start their job at a certain time. To make sure people didn’t oversleep, knocker-uppers also known as wake-up helpers appeared. They made money by waking people up. Every morning, they would walk down the street knocking on doors or windows with sticks. As alarm clocks grew popular in the 1930s and 1940s, knocker-uppers weren’t needed any more. Today, our sleep is mainly influenced by both social stress and electronic products. Falling asleep becomes hard and sleeping quality goes down. Put screens away 30 to 60 minutes before bedtime. Keep a comfortable bedroom temperature, avoid bright light and reduce the nearby noise. These will help you relax and wind down. If you have lots of thoughts or worries, writing them down before bedtime can help you put them aside for the night.
