All of us, at some point, experience nights where we have difficulty falling asleep or staying asleep. The National Institute of Health estimates that one in three adults has bouts of infrequent sleeplessness or insomnia, while one in 10 sufferes from chronic insomnia. Being unable to get a good night's sleep can cause disruptions in our day?to?day life. But persistent sleeplessness can lead to physical and emotional health problems.

The body needs sleep to rejuvenate itself and rebuild the cells necessary to keep the immune system strong and the brain functioning properly. Everyone's body requires a different amount of sleep to accomplish these goals. The average amount of sleep needed by an adult is around seven or eight hours a night. However, some people can function quite well with less than that, while others need more to be at peak performance.

Sleeplessness can be caused by many different things. Most people experience sleeplessness for a short period of time due to an outside stimulus such as stress, improper diet, a poor sleeping environment or an acute medical concern such as the flu. 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 or the emotional pain of anxiety and depression.

Prolonged sleeplessness can have a negative effect on the way the body performs daily tasks. Those that suffer from sleepless nights may find themselves feeling drowsy or fatigued during the day. The ability to concentrate or focus on a task diminishes and you are less mentally alert. Because the body needs sleep to support a healthy immune system, those that are sleep?deprived may be more susceptible to both acute and chronic illnesses such as high blood pressure and diabetes.

Sleeplessness not only takes a toll on your physical self but also your emotional well?being. Being unable to sleep well for a few nights may only produce minor irritability. 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 such as sleeping pills and alcohol to aid them in their quest for a good night's sleep.

There are numerous home remedies for mild sleeplessness. Prepare your body for sleep by avoiding caffeinated drinks such as tea or coffee before bed. Don't exercise strenuously before bedtime; instead do something relaxing such as meditate or take a warm bath. Go to bed only when you feel sleepy and not because of a self?appointed bedtime.Finally, create a favorable sleeping environment by removing stimulants from your bedroom such as extra lighting or a television. If you still cannot find relief, it may be time to visit your physician for help. A sleep study will be done that can help to determine the cause of the sleeplessness and possible solutions.
