Sleeplessness can be caused by many different things. Most people experience sleeplessness for an outside stimulus (刺激) such as stress, improper diet or a poor sleeping environment. Once the stimulus passes, the ability to sleep will usually return. Chronic sleeplessness may be caused by ongoing health concerns such as the physical pain of arthritis (关节炎) or the emotional pain of anxiety and depression.

　　Those that suffer from sleepless nights may find themselves feeling sleepy or tired during the day. The ability to concentrate or focus on a task reduces and they are less mentally alert. Because the body needs sleep to support a healthy immune system, those who have little sleep may be more affected by both acute and chronic illnesses like high blood pressure and diabetes.

　　Sleeplessness not only has effects on your physical self but also your emotional well­being. Being unable to sleep well for a few nights may only produce anger. However, if sleeplessness becomes chronic, the price could be much higher in the form of anxiety, depression and possibly substance abuse. Those with chronic sleeplessness may turn to controlled substances like sleeping pills and alcohol to help them have a good night’s sleep.

　　There are numerous ways for mild sleeplessness at home. Prepare your body for sleep by avoiding drinks such as tea or coffee before bed. Don’t exercise too much before bedtime; instead, do something to relax yourself. Finally, create a favorable sleeping environment by removing stimulants from your bedroom like extra lighting or a television. If you still cannot find relief, it may be time to visit your physician for help.
