Insomnia Essays - GABAA Receptor Positive Allosteric Modulators Insomnia Insomnia is caused by everyday situations involving emotional extremes of happiness or anxiety. Although the term insomnia literally translates into no sleep, it is used by most people to describe trouble falling asleep or staying asleep. The consequence of this is being unable to function as well as usual the following day. About one in three American adults says he or she is a poor sleeper and one in six says the problem is quite serious. Insomnia knows no bounds it can affect the young and old male or female. Sleep specialists distinguish among three types of insomnia: transient, short term and chronic. Transient insomnia is the experience of a night or two of poor sleep. Probably everyone suffers from it now and then. Often people who experience transient insomnia complain of difficulty in concentrating, weariness and irritability the following day. Sleeping in a strange bed may even bring on transient insomnia. Most people do not sleep quite as well as usual their first night away from home, whether it is a pleasant visit to a friends house or a vacation or under the stressful conditions of a hospital stay. Short-term insomnia involves sleep disturbances that last for two to three weeks. Here, ongoing stress at school, work or home is often the reason: worrying about grades, learning of your parents impending divorce or having a serious illness or death in the family are all events that trigger short-term insomnia. Chronic insomnia is poor sleep that last longer than three weeks. This form of insomnia is a complex disorder with many possible causes and afflicts more than 35 million Americans. While most people blame this on stress, the use of stimulants may also be at fault. It is relatively easy to pinpoint the reasons for transient and short-term insomnia. That is not the case for chronic insomnia, which may last for years disrupting sleep most or every night. Rapid travel across many time zones upset the inner clocks that regulate the timing of sleeping and waking. As a result, trouble in sleeping at night as well as staying awake throughout the day is commonly called jet lag but is actually a form of insomnia. Stress undoubtedly plays a key role in insomnia, particularly for teenagers and people in their 20s and 30s, but is by no means the only culprit. As mentioned before stimulants are also responsible for cases of insomnia. Even though caffeine near bedtime may not interfere with falling asleep, it may trigger awakenings later. Caffeine related ingredients are found in soft drinks, chocolate, coffee and strong tea. Nicotine is also a stimulant and it has been shown that smokers take longer to fall asleep and sleep more lightly than non-smokers. Ni cotine may be found in many commonly used drugs, including non-prescription drugs for weight loss, asthma and colds. Alcohol, which is sometimes used as a nightcap to induce sleep, may also act to make sleep more fragile throughout the night. Noise is also a cause for insomnia, passing traffic outside your window, jets flying by overhead, or your TV left on during your sleep may disturb your sleep even though you dont awaken completely. Some expert believe that having a white noise such as a fan or the static of a radio to mask the disturbing sounds can act as a shield against any kind of sudden noise that could jolt you out of sleep. Even when your eyes are closed, light still comes through and this again may not awaken you but will cause for a less stable state of sleep. Pain is also a reason for insomnia, disorders such as arthritis, back injury, headache and many other forms of discomfort may also upset sleep. A nationwide study of 8,000 patients seeking treatment at sleep disor der centers shows that physical problems such as trouble with breathing or over active leg muscles account for over half of all cases in chronic insomnia. This startling finding makes sleep specialists think that insomnia is not always an illness but a symptom, much like a fever or headache. Insomnia can take major tolls on a family with a member who suffers from insomnia the person can be irritable, anxious and have impaired concentration and
