    All people need to sleep. Sleeping is a restorative (恢复体力的) process that shapes better body functions and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.

    Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom is also used as a place for your life and work, you will probably have a poor sleep. Bedrooms should be designed and used for sleep mainly. TVs, computers and other things should not be in your bedroom at all if possible.

    The regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise programme. Proper exercise and healthy food will help improve sleeping quality. However, avoid exercising 2 hours before sleeping, since this may keep your body exciting and make sleeping more difficult.

    A pre-bedtime rule will help you focus on sleep. You can try meditation (沉思), reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a special style. Do what is the best for you.

    Things such as room temperature, noise and light levels and even your bed itself can have a lot of effect on the quality of sleep that you experience. Cut down the annoying noises and lights. You are in your bedroom to sleep and not be distracted (干扰) by environment.

—No, I don't. Let's ask our teacher for help.
