All people need to sleep. Sleep is a necessary process that promotes proper body functioning 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 also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible.
Establishing 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 program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
Establish a pre-bedtime rule that will help focus you 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 specific category. Do what is the best for you.
Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences（干扰）.
