What is Insomnia

What is Insomnia?

Insomnia is defined as difficulty in falling asleep, difficulty staying asleep, or waking up early in the morning and not being able to return to sleep. In general, people with insomnia sleep less or sleep poorly despite having an adequate chance to sleep. Poor sleep may lead to trouble functioning during the daytime.

Insomnia is not defined by the number of hours slept because “sufficient sleep” can vary from one person to another. Sleep requirements may also decrease with age. The question is how can i overcome insomnia?

Insomnia is the most common sleep complaint. While almost everyone has an occasional night of poor sleep, approximately 10 percent of adults have long-term or chronic insomnia.

This information will review the symptoms, causes, diagnosis of insomnia, and the treatment for insomnia.  

Insomnia Symptoms

The function of the Adenoid is to produce antibodies. The adenoid produces B-cells, giving rise to IgG and IgA plasma cells. In children aged 4–10 years, adenotonsillectomy does not appear to cause significant immune deficiency.

What happens when the Adenoid gets hypertrophy?

• Difficulty falling asleep or staying asleep
• Variable sleep, such as several nights of poor sleep followed by a night of better sleep
• Daytime fatigue or sleepiness
• Forgetfulness
• Poor concentration
• Irritability
• Anxiety
• Depression
• Reduced motivation or energy
• Increased errors or accidents
• Ongoing worry about sleep

For many people, the symptoms of insomnia interfere with personal relationships, job performance, and daily function. People with insomnia may have small differences in memory and problem solving compared with people without insomnia. However, they seem to have similar abilities on tests of general cognitive function, perception, verbal ability, attention, and complex thinking.

People with insomnia have an impaired sense of sleep. You may feel that you have not slept, even if testing shows that you have. You may also feel more fatigued than individuals without insomnia, even if testing indicates that you are less sleepy. This impaired sense of sleep may be related to a problem with the body’s sleep-arousal system, which normally helps you feel awake after sleeping and feel tired before going to bed.

One result of poor sleep is that you may become concerned that you will be sleep-deprived and will suffer from serious consequences of lost sleep. This concern may grow as you are unable to sleep, which in turn makes it increasingly difficult to fall asleep. It is important that you not get caught in this cycle and understand that you are sleeping more than it seems.

Insomnia Causes

Short-Term Insomnia lasts less than three months and is usually associated with stressors. Possible stressors include the following:

• Changes in the sleeping environment (temperature, light, noise)
• The loss of a loved one, divorce, or job loss
• Recent illness, surgery, or sources of pain
• Use or withdrawal from stimulants (caffeine), certain medications (theophylline, beta-blockers, steroids, thyroid replacement, and asthma inhalers), illegal drugs (cocaine and methamphetamine), or alcohol

Short-term insomnia often resolves when the stressor resolves

Situations that disrupt your normal sleep cycle can also cause insomnia. Some examples of this include:

• Jet lag – Traveling across time zones can cause insomnia, known as jet lag, may occur regardless of the direction of travel, although it is most pronounced when traveling west to east. Most people require several days to adjust their sleep patterns to the new time zone.
• Shift work – Individuals who work the night shift commonly experience insomnia. You may be sleepy at work and while driving home in the morning, but have difficulty staying asleep past noon. The sleep problems can be resolved by transferring from the night shift or by sleeping at the same time every day including weekends for several weeks.

Long-term insomnia (or chronic) insomnia lasts longer than three months and occurs at least three nights per week. Insomnia often occurs with other conditions, including:

• Mental health problems, such as depression, anxiety disorders (including panic attacks), and posttraumatic stress disorder
• Medical illnesses, especially those that cause pain, stress, or difficulty breathing
• Neurological disorders, such as Parkinson disease and Alzheimer disease
• Other sleep disorders, such as sleep apnea, restless legs syndrome, periodic limb movements, and circadian rhythm disorders
• Medications or illegal drug use Irregular sleep habits Insomnia can also occur on its own
• In some cases, it can begin in childhood or be passed along in families

Short Duration Sleep and Sleep Deprivation

Insomnia is frequently confused with short sleep requirement and sleep restriction:

• Sleeping for only a short period of time is common among people who have insomnia. However, some people normally require little sleep and can function without difficulty after sleeping for only a few hours. People who sleep less but have no residual daytime sleepiness or other symptoms are called short sleepers and do not have a sleep problem. In addition, you may need less sleep as you get older. Needing less sleep does not necessarily mean that you have insomnia unless you also have daytime symptoms, such as sleepiness or dysphoria.
• People who have a reduced time in bed (sleep restriction), as well as those with insomnia sleep for a short time, have difficulty functioning during the daytime. However, sleep-restricted people will fall asleep quickly and sleep normally if given the opportunity. Chronic loss of sleep, caused by spending fewer than eight hours in bed on most nights, is probably the most common cause of sleepiness. Patients with insomnia are unable to sleep normally when they are given the chance to sleep.

Insomnia Diagnosis

If you seek help for insomnia, your doctor or nurse will start by asking you how many hours you slept and what problems you have had with sleep, insomnia nursing diagnosis over a typical 24-hour period. Your bed partner or caregiver can help to answer these questions because you may not be aware of what happens while you sleep.

You may be asked to keep a daily sleep log, which is a record of sleep times for one to two weeks.

Your doctor insomnia specialist or nurse may ask other questions to determine the cause of your insomnia. A physical examination may be performed to determine if there are medical or neurologic conditions causing or worsening your sleep problems.

Laboratory tests may be recommended to help identify underlying medical or sleep disorders, best strains for insomnia​, although this is not required for everyone with insomnia. Laboratory tests may include polysomnography or actigraphy:

• Polysomnography – is a formal sleep study done in a sleep laboratory. It uses monitors that are attached to your body to record movement, brain activity, breathing, and other physiologic functions. This test may be used when an underlying sleep disorder is suspected or if your insomnia has not responded to treatment.
• Actigraphy – records activity and movement with a monitor or motion detector, generally worn on the wrist throughout the day and the test is conducted over one to two weeks at home to gather estimates about how much and at what time you are sleeping.

Circadian Rhythm Disorders

Circadian rhythms are changes in body functions, such as temperature regulation and sleep cycles, which occur for 24 hours. People with circadian rhythm disorders may experience insomnia and daytime sleepiness because their circadian rhythms follow an abnormal pattern.

Shift work sleep disorder – People who work late night shifts can have difficulty sleeping during the daytime. This is especially true for people who work rotating or permanent night shifts, who often revert to sleeping at night on days o to maintain contact with their family. Treatment often includes adopting a consistent daily sleep routine seven days per week.

Delayed sleep phase syndrome – Some people have a sleep-wake rhythm that is longer than 24 hours. These people want to go to bed later and sleep later every morning. However, this is usually not practical because of school or work requirements. Treatment usually includes trying to wake at an earlier, consistent time each day.

Advanced sleep phase syndrome – This is the opposite of delayed sleep phase syndrome and is more common in middle age and older adults. A person with this disorder may go to sleep in the early evening and wake much earlier than they wish. Attempts to stay up later do not always allow the person to wake later in the morning. Sleep can be normal if the person is willing to accept the early bedtime and wake time.
