睡眠健康：了解睡眠问题与评估

Original source overview

What is sleep?While you are sleeping your brain and body functions are still active. Sleep is a natural process that helps your body restore energy, supports learning and memory, and keeps you healthy.

It's not just the number of hours of sleep you get that matters. The quality of your sleep is also important. During the night, your brain cycles through different stages of non-rapid eye movement (non-REM) sleep and rapid eye movement (REM) sleep. If your sleep is often interrupted, you may not get enough time in certain stages of sleep. Poor-quality sleep does more than make you feel tired. It can affect your physical and mental health, thinking, and daily functioning.

What are sleep disorders?Sleep disorders are conditions that disturb your normal sleep patterns. There are many types of sleep disorders. Some general types include:

• Insomnia, which is trouble falling asleep or staying asleep. • Sleep-related breathing disorders such as sleep apnea, a condition in which you stop breathing for 10 seconds or more during sleep. • Sleep-related movement disorders such as restless leg syndrome (RLS), which involves tingling or prickling sensations in your legs, and a strong urge to move them. • Hypersomnia, which is extreme daytime sleepiness. This includes narcolepsy. • Circadian rhythm sleep-wake disorders, which are problems falling asleep or waking up at the right times. This may be due to shift work or jet lag. • Parasomnia, which is unusual behaviors during sleep or while falling asleep or waking up. This may include sleepwalking, talking, or eating during sleep.

Some people who feel tired during the day have a true sleep disorder, while others simply don't get enough sleep. The amount of sleep you need depends on your age, lifestyle, health, and sleep patterns. Most adults need about 7-9 hours each night.

What causes sleep disorders?There are different causes for different sleep disorders. They may include:

• Other health conditions, such as heart disease, lung disease, nerve disorders, or pain • Mental illnesses, including depression and anxiety • Medicines • Genetics

Sometimes the cause is unknown.

Other factors that may contribute to sleep problems include:

• Using caffeine or alcohol • Having an irregular schedule, such as working the night shift • Aging, since older adults may sleep less, spend less time in deep sleep, and wake easily

What are the symptoms of sleep disorders?The symptoms of sleep disorders depend on the specific disorder. Some signs that you may have a sleep disorder include that:

• You regularly take more than 30 minutes to fall asleep. • You regularly wake up several times and then have trouble falling back to sleep, or you wake up too early in the morning. • You often feel sleepy during the day, take frequent naps, or fall asleep at the wrong times during the day. • Your bed partner says that when you sleep, you snore loudly, snort, gasp, make choking sounds, or stop breathing for short periods. • You have creeping or tingling sensations in your legs or arms that are relieved by moving or massaging them, especially in the evening and when trying to fall asleep. • Your bed partner notices that your legs or arms jerk often during sleep. • You have vivid, dreamlike experiences while falling asleep or dozing. • You have episodes of sudden muscle weakness triggered by strong emotions. • You feel as though you cannot move or speak for a brief time when you first wake up.

How are sleep disorders diagnosed?To diagnose a sleep disorder, your health care provider will review your medical and sleep history and do a physical exam. You may also have a sleep study (polysomnogram). Most sleep studies monitor and record data about your body during a full night of sleep. The data includes:

• Brain wave activity • Eye movements • Breathing rate • Blood pressure • Heart rate and electrical activity in the heart and other muscles

Other types of sleep studies may check how quickly you fall asleep during daytime naps or how well you can stay awake during the day.

What are the treatments for sleep disorders?Treatments for sleep disorders depend on which disorder you have. They may include:

• Practicing good sleep habits and other lifestyle changes, such as eating a healthy diet and getting regular exercise • Reducing anxiety about sleep with cognitive behavioral therapy or relaxation techniques • Using a CPAP (continuous positive airway pressure) machine for sleep apnea • Using bright light therapy (in the morning) • Taking sleep aid medicines, or natural products such as melatonin

Always check with your provider before taking any medicine or supplement. Most sleep aid medicines are generally for short-term use.

Encyclopedic background — Wikipedia

The following selected excerpts provide background on “Sleep disorder”. This related background source does not cover every aspect of the specific topic “Sleep Disorders”; population-specific details and decisions should be checked in the original topic source. They are not a substitute for the source overview or current local clinical guidance. Each excerpt below comes from the fixed Wikipedia revision [W1].

Definition and overview [W1]

A sleep disorder, or somnipathy, is a medical disorder that disrupts an individual's sleep patterns and quality. This can cause serious health issues and affect physical, mental, and emotional well-being. Polysomnography and actigraphy are tests commonly ordered for diagnosing sleep disorders.

Sleep disorders are classified by the International Classification of Sleep Disorders into insomnia disorders, sleep-related breathing disorders (such as obstructive sleep apnea), central disorders of hypersomnolence (such as narcolepsy), circadian rhythm sleep disorders, parasomnias, and sleep-related movement disorders. When a person struggles to fall or stay asleep without an obvious cause, it is referred to as insomnia, which is the most common sleep disorder. Other sleep disorders include sleep apnea, narcolepsy, idiopathic hypersomnia (excessive sleepiness at inappropriate times), restless legs syndrome, jet lag disorder, rapid eye movement sleep behavior disorder, sleepwalking, and night terrors (also known as sleep terrors).

Sleep disruptions can be caused by various issues, including teeth grinding (bruxism). Managing sleep disturbances that are secondary to mental, medical, or substance abuse disorders should focus on addressing the underlying condition. Sleep disorders are common in both children and adults. However, there is a significant lack of awareness about sleep disorders in children, with many cases remaining unidentified. Several common factors involved in the onset of a sleep disorder include increased medication use, age-related changes in circadian rhythms, environmental changes, lifestyle changes, existing physiological problems, and stress. Among the elderly, the risk of developing certain sleep conditions is especially high. These include sleep-disordered breathing, periodic limb movements, restless legs syndrome, REM sleep behavior disorder, insomnia, and circadian rhythm disturbances.

Causes [W1]

A systematic review found that traumatic childhood experiences, such as family conflict or sexual trauma, significantly increase the risk of several sleep disorders in adulthood, including sleep apnea, narcolepsy, and insomnia.

An evidence-based synopsis suggests that idiopathic REM sleep behavior disorder may have a hereditary component. A total of 632 participants, half with idiopathic REM sleep behavior disorder and half without, completed self-report questionnaires. The study results suggest that people with the sleep disorder are more likely to report having a first-degree relative with the same sleep disorder than people of the same age and sex who do not have the disorder. More research is needed to further understand the hereditary basis of sleep disorders.

Obstructive sleep apnea is a common condition affecting 10-20% of middle-aged and older adults, characterized by repeated breathing pauses during sleep, leading to poor sleep quality, and excessive daytime somnolence and, sometimes insomnia. Common factors include obesity, narrow airways, and certain neuromuscular conditions that cause airway collapse during sleep.

Classification (ICSD-3, 2023) [W1]

Insomnia is the most frequent sleep disorder. It may occur on its own or be associated with other conditions such as mental disorders (such as stress, anxiety, or depression). It can also be associated with medical conditions such as asthma, diabetes, heart disease, pregnancy, and neurological disorders

Reading this topic in context

Use “Sleep Disorders” as a starting point for a focused discussion, rather than treating every statement in the broader encyclopedia article as applying to you. The original source overview and the background excerpts answer different questions: the overview explains the health topic for readers, while the encyclopedia supplies terminology and general context. Keep a record of which questions concern symptoms, a confirmed diagnosis, prevention, or an existing treatment. This helps a healthcare professional address the relevant issue without relying on an internet label.

Questions to take to a professional

1. Which sleep disorder is being considered?

2. What sleep diary, medicine review or testing would be useful?

Evidence, scope and next steps

The health-topic overview is attributed to MedlinePlus / the National Library of Medicine at the original topic link below. Wikipedia [W1] is a secondary background source; its references can support further reading, but their presence is not evidence that WellPrimer has independently reviewed every study. No clinical review, guideline certification or NLM endorsement is claimed. For screening intervals, diagnostic thresholds, pregnancy or child-specific advice and treatment choices, check current guidance in your country with a qualified professional. Do not start, stop or change a prescribed medicine based on encyclopedia excerpts. New or worsening symptoms need appropriate clinical assessment rather than more reading alone.
